Innovation & Flight

New York, NY

Filmmaker Cecil B. DeMille lived at this New York address from 1906 to 1913, in the years before he headed west to help invent Hollywood. In 1913 he directed 'The Squaw Man,' celebrated as the first feature-length film made in Hollywood, launching a career of some 70 pictures. Famed for lavish spectacles like 'The Ten Commandments,' DeMille became one of the defining showmen of American cinema.

Brush Creek Township, OH

In the hills of Adams County, Ohio, Cedar Run once powered a small industrial world. The first mill here rose in 1811 to serve a nearby iron furnace, part of the charcoal-iron trade that dotted the Appalachian foothills before the furnace went cold in 1840. Milling continued when Fisher and Stewart raised a new grist mill in 1844, and a generation later its owners traded the fickle water wheel for a steam engine, its tall brick smokestack marking the arrival of a new industrial age.

San Antonio, TX

Evangelist David Pennington organized this Disciples of Christ congregation in 1883 and built its first sanctuary here in 1884, just as the arrival of the railroad set San Antonio booming. The church grew with the city, helped found the Mexican Christian Institute to minister to refugees fleeing Mexico's revolution, and organized a Spanish-speaking Disciples congregation. A pioneer of religious broadcasting, it aired the city's first radio worship in 1924 and its first televised services in 1954.

Washington County, OR

This rose garden was dedicated in April 1986, weeks after the Space Shuttle Challenger broke apart shortly after launch on January 28, 1986, killing all seven aboard. Its plaque lists the crew—including teacher Christa McAuliffe, chosen to be the first ordinary citizen in space—and carries her words, "I touch the future; I teach." The disaster was witnessed live by millions of schoolchildren.

Apalachicola, FL

This Apalachicola garden preserves the memory of Dr. Chapman, a physician and self-taught botanist who lived in the little Gulf Coast town for much of the 19th century. From this remote outpost he catalogued the plant life of the American South, producing a landmark flora that earned him recognition well beyond Florida. His careful fieldwork made a small port town an unlikely center of botanical science.

Chapman Ranch, TX

In 1919 Philip Chapman bought nearly 35,000 acres of the King Ranch's Laureles Division and sent his son to carve it into tenant farms. The venture grew into a company town with schools, a hospital, and its own power plant, and by the late 1920s Chapman Ranch was billed as the world's largest mechanized farm, testing new equipment and breeding a prized long-staple cotton. The town faded by 1941, though the family still ranches the land.

Camp Wood, TX

Before he was the most famous man in the world, Charles Lindbergh was a barnstormer called "Slim" who flew a surplus World War I biplane to Texas so he could say he'd flown there. In March 1924 he landed near Camp Wood and, attempting to take off the next day, harmlessly crashed into Warren Puett's store—an incident the townsfolk forgave and remembered fondly. Weeks later he entered Army flight training at San Antonio, and in 1927 made his history-making solo flight from New York to Paris.

Lancaster, PA · est. 1983

Charles Demuth, born in Lancaster in 1883, became one of America's foremost modernist painters, working from the family home where he spent most of his life. His crisp, geometric "Precisionist" canvases like "My Egypt" and the poster-portrait "I Saw the Figure 5 in Gold" translated grain elevators, factories, and city signs into a distinctly American visual language. Though he traveled widely, he returned always to Lancaster, where he died in 1935.

Bonham, TX

Born in Bonham in 1916 to musical parents, Charlie Christian developed a distinctive single-string guitar style that helped pioneer the electric guitar as a lead instrument. He joined Benny Goodman's band in 1939 and played with jazz greats and at Carnegie Hall before tuberculosis took his life at just twenty-five.

Louisville, KY

This memorial gateway honors Charles Hermany (1830–1908), who spent nearly half a century as chief engineer of the Louisville Water Company. In an era when waterborne disease killed thousands in American cities, Hermany helped pioneer sand-filtration methods that made public water supplies markedly cleaner and safer. Erected in 1930, the gateway marks the enduring importance of the men who built the unseen infrastructure of a growing industrial city.

Loretto, PA · est. 1947

Charles M. Schwab rose from humble beginnings in this Cambria County region to become one of the titans of American steel, so gifted that Andrew Carnegie reportedly said he knew more about steel than any man alive. At the height of his fortune Schwab kept a grand estate near Loretto, later given over to St. Francis College. His story tracks the explosive growth of the steel industry that powered America's rise as an industrial giant.

Pittsburgh, PA · est. 1998

Here in 1888 the young inventor Charles Martin Hall's method of producing aluminum by electrolysis was first put to commercial use by the Pittsburgh Reduction Company — the firm that would grow into industrial giant Alcoa. Before Hall's breakthrough, aluminum was a rare and costly novelty; his process made the lightweight metal cheap and abundant. What began as a Pittsburgh experiment turned aluminum into a staple of the modern age.

Thompson Township, OH

In the years after the Civil War, American ingenuity was racing to turn laboratory chemistry into world-changing industry, and few breakthroughs matched what a young Ohioan achieved in a woodshed laboratory. Working just after his college years, Charles Martin Hall discovered an inexpensive electrolytic method to extract aluminum, a metal that had until then been rarer and costlier than silver. His process transformed aluminum from a precious curiosity into an everyday material and seeded a major American industry.

Westfall Township, PA · est. 1948

In this house on the Delaware, from 1887 until his death in 1914, lived Charles Sanders Peirce—scientist, logician, and the founder of the philosophy known as pragmatism. Often called America's most original philosopher, he produced much of his groundbreaking work here in relative isolation and poverty. His ideas on logic, meaning, and inquiry would deeply influence later American thought.

Doylestown, PA · est. 1999

Charles Sheeler became one of America's leading modernists, developing a cool, machine-inspired style known as precisionism that found beauty in factories, skyscrapers, and the plain geometry of Bucks County barns. From 1910 to 1926 he rented the Worthington House in Doylestown, where he produced influential early paintings and photographs. His clear-eyed vision helped define how modern America saw its own industrial and rural landscapes.

Carson City, NV

This was the home and observatory of Charles William Friend, Nevada's first weatherman, astronomer, and seismologist. Born in Prussia in 1835 and drawn to California by the 1849 Gold Rush, Friend settled in Carson City in 1867 and opened a jewelry and optical store. He built Nevada's first observatory here, equipped through the help of U.S. Senator William Stewart, and in 1887 founded the state's first weather service, directing a network of volunteer stations whose data is still cited today.

Palos Township, IL

This blunt Department of Energy plaque marks "Plot M," the spot where waste from the pioneering nuclear research at nearby Site A was buried between 1943 and 1949. The six corner markers it describes fence off the resting place of radioactive material left over from the earliest experiments of the atomic age. Placed in 1978, it is both a safety notice and an artifact of how a young science handled its own byproducts.

Palos Township, IL

On the bluffs of Cook County's forest preserves, this quiet site once hummed with the opening chapter of the atomic age. After Enrico Fermi's team achieved the world's first controlled nuclear chain reaction under the University of Chicago's stands in 1942, the work moved here to "Site A," where the reactor was rebuilt as CP-2 and joined by CP-3, the first heavy-water-moderated reactor. These wartime facilities anchored the Argonne research that grew into a national laboratory.

Childress, TX

During World War II the U.S. Army Air Forces opened a bombardier and navigation school on some 2,400 acres west of Childress, active by October 1942. Cadets trained in intense 18-week courses, and 'skip-bombing' practice at Lake Childress drew crowds, while the base hosted the first 'All-American Precision Bombing Olympics' in 1943. More than a tenth of all U.S. bombardiers—4,791 men—trained here before the field closed in December 1945 and became the town's municipal airport.

Storey County, NV

First located in 1859, the Chollar was one of the Comstock Lode's leading mines, consolidating with the Potosi in 1865 to form the storied Chollar-Potosi. The Nevada mill was built here in 1887 to work low-grade Chollar ore, and it holds a notable double distinction: it was the last mill on the Comstock to use the old Washoe pan amalgamation process, yet the first to generate and use its own electric power.

Monessen, PA · est. 1999

The steel town of Monessen produced more than iron and glass — it gave the world a Nobel laureate. Christian B. Anfinsen, born here in 1916, became a biochemist whose work on the enzyme ribonuclease helped reveal how a protein's chain of amino acids alone determines its folded, functional shape. That insight, honored with the 1972 Nobel Prize in Chemistry, came during decades leading a laboratory at the National Institutes of Health before he turned to teaching at Johns Hopkins.

Philadelphia, PA · est. 2005

Opened in May 1861 as the first U.S. Army hospital of the Civil War, the Christian Street Hospital became a place of medical discovery as well as healing. Here Drs. S. Weir Mitchell, William Keen, George Morehouse, and colleagues studied nerve injuries among wounded soldiers, using electricity and drugs to pioneer the treatment of neurological disorders. The hospital closed in 1865 as the war ended.

Liberty Township, PA · est. 1947

Christopher Latham Sholes was born near here in 1819 and learned the printing trade as a young man in Danville before heading west to Wisconsin at twenty. There he tinkered his way to a machine that would reshape communication and the workplace: the typewriter, for which he received his first patent in 1868. His invention put the printed word within reach of every office and eventually opened new employment to a generation of workers.

Danville, PA · est. 1948

Born in the Susquehanna Valley in 1819, Christopher Latham Sholes learned the printer's trade in Danville before heading west to Wisconsin as a young man. There, tinkering with type and machinery, he devised the first practical typewriter, receiving his initial patent in 1868. His invention put the familiar keyboard into offices across the world and helped open clerical work to a new generation of workers.

Weslaco, TX

The Rio Grande Valley's red-meat grapefruit was born of the region's saline-alkaline soil, bred from Thompson Pink budded onto sour orange rootstock. In 1929 nurserymen A. E. Henninger of Mission and Dr. J. R. Webb of Donna each found red fruit in their orchards; they cast lots, and Henninger won the right to patent his "Ruby Red" as U.S. Plant Patent No. 53, while Webb's "Red Blush" proved equally popular. Both rose-fleshed, red-tinged varieties became sweet, early-ripening favorites.

Dare County, NC

In 1942, with German U-boats prowling the Atlantic shipping lanes just offshore, the Civil Air Patrol opened North Carolina's first Coastal Patrol Base half a mile to the southeast. Flying their own small planes, civilian pilots scanned the water for submarines and stood ready to support the military's defense of the coast. Their volunteer patrols filled a dangerous gap in the nation's early wartime air cover.

Port Lavaca, TX

In February 1863 local inventor E. G. Singer tested a torpedo with a novel spring-action ignition system on the shores of Lavaca Bay. With partner Dr. J. R. Fretwell, Captain David A. Bradbury, and other Lavaca citizens, Singer won Confederate authority to manufacture underwater and land mines at an experimental works here. His devices were installed in rivers across the South, from Mississippi's Yazoo to Alabama's Mobile Bay, and helped defend the Matagorda Bay area throughout 1863.

Temple, TX

Claudia Potter graduated from the University of Texas Medical Branch in 1904 as the only woman in her class and just the sixth woman to finish the program. Hired in 1906 by Dr. Arthur C. Scott, she became the first woman line physician for the Gulf, Colorado and Santa Fe Railway and an anesthetist at the Temple Sanitarium—earning far less than her male peers. Regarded as Texas's first full-time anesthesiologist and the first to give nitrous oxide by machine, she trained many nurse anesthetists and helped build Scott and White into a leading surgical center over 41 years.

Temple, TX

Claudia Potter, one of eight children of a Denton County family, earned her degree from the University of Texas Medical Branch in 1904 and joined Temple's Scott and White Hospital as its first woman doctor. Over a 41-year career she became a pioneering specialist in the young field of anesthesiology, widely respected before retiring in 1947. She died in 1970, a day short of her 89th birthday.

Town of Aurora, NY

Clifford Robert Pettis (1877–1927) was a pioneering figure in New York's early conservation movement, rising to serve as the state's Superintendent of Forests. Working in the decades after the 1885 creation of the Adirondack and Catskill Forest Preserves, foresters like Pettis helped establish state tree nurseries, large-scale reforestation, and the scientific management of woodlands at a time when American forestry was still a young profession. This memorial in the Town of Aurora honors his life's work during the conservation era that followed the unchecked logging of the Gilded Age.

Corry, PA · est. 1987

From 1888 to 1928 the Climax plant in Corry turned out more than a thousand geared steam locomotives—rugged, slow-moving engines designed to haul heavy loads up steep, rough, temporary track. Logging railroads across the United States and abroad relied on them to reach timber that conventional locomotives could never touch.

Gloucester, MA

On a small granite hump in Gloucester Harbor called Ten Pound Island, the U.S. Coast Guard opened one of its earliest air stations in May 1925, putting seaplanes to work spotting rum-runners and answering distress calls along a busy New England coast. This monument honors the officers and airmen who turned an experimental idea — flying boats in the service of lifesaving and law enforcement — into a permanent arm of the service. It marks the birthplace of a continuous Coast Guard aviation tradition that endures today.

Erie, PA · est. 2001

Erie native Philip Cochran carved out a reputation as one of World War II's most colorful airmen. He first drew notice flying P-40 fighters in North Africa, then commanded the 1st Air Commando Group during the 1944 Allied campaign in Burma, pioneering the use of gliders and light aircraft to insert troops deep behind Japanese lines. A colonel at 33, he earned the Distinguished Service Medal and Britain's Distinguished Service Order—and inspired cartoonist Milton Caniff's characters Flip Corkin and General Philerie.

Harrodsburg, KY

A Mercer County native and Marine veteran of World War II and Korea, Colonel George Morgan Chinn (1902–1987) became one of the nation's foremost authorities on automatic weapons. His firsthand study of weapons in combat produced the five-volume Navy-sponsored work The Machine Gun, and as a Vietnam-era consultant he helped develop grenade launchers later used through the Persian Gulf War. In 1960 he also served as director of the Kentucky Historical Society and wrote extensively on pioneer Kentucky.

Orlando, FL

This Orlando park honors Joe Kittinger, an Air Force test pilot celebrated as a pioneer of the edge of space. In the Project Excelsior high-altitude balloon program around 1960, he rode an open gondola to the stratosphere and made record-shattering parachute jumps, gathering data that helped make crewed spaceflight survivable. Decades later, in 1984, he became the first person to cross the Atlantic solo in a gas balloon.

Goshen Township, OH

In the skies over southern Europe during World War II, the 15th Army Air Force flew long, dangerous missions from bases in Italy, escorting heavy bombers deep into enemy territory. John J. Voll, a young man from Goshen, Ohio, rose to become the highest-scoring fighter ace of that entire air force, downing twenty-one enemy aircraft from the cockpit of his P-51 Mustang. In an era when air power was still coming into its own, pilots like Voll turned the sleek, long-range Mustang into one of the most decisive weapons of the war.

Arlington, TX

Raised in Arlington, Neel Kearby earned a business degree and joined the Army Air Corps, rising to command the 348th Fighter Group in the Pacific during World War II. Flying the bulky P-47 Thunderbolt he had drilled his pilots to fight aggressively, he ran up 22 aerial victories—including a record six enemy planes downed in a single mission on October 11, 1943, which earned him the Medal of Honor. He was killed in action over New Guinea in March 1944.

Cambridge, MA

In October 1958, MIT fraternity pledge Oliver R. Smoot was laid end-over-end 364 times to measure the Harvard Bridge over the Charles River, giving the world a delightfully absurd unit: the Smoot, equal to his own five-foot-seven height. The bridge came out to '364.4 Smoots plus one ear,' and the paint marks his Lambda Chi Alpha brothers laid down have been faithfully repainted by generations of pledges ever since. This plaque, dedicated to Smoot, MIT Class of 1962, marks the 50th anniversary of a prank that outlived its pranksters' expectations.

Philadelphia, PA · est. 2006

At 3747 Ridge Avenue in Philadelphia, the computer age turned commercial. Here BINAC passed its verification tests in 1949 as the world's first commercial, electronic, stored-program digital computer, followed in 1951 by the customer acceptance of UNIVAC I. Both machines were led by J. Presper Eckert and John W. Mauchly, the same duo who had built the pioneering ENIAC.

Euless, TX

Euless's sandy, well-drained soil made it a natural cradle for commercial horticulture, an industry pioneered here beginning in the 1800s. Kentucky native Ambrose H. Boyd founded Tarrant County Nurseries in 1879, and his son John helped organize the state's nurserymen's association; Arch N. Cannon, trained under Boyd, launched Euless Nurseries in 1897 and bred his own fruit and rose varieties, including the "Cannon's Wonderful" and a rose named "Louise." Shipping stock across the region, these families made nursery growing the area's most profitable enterprise well into the twentieth century.

Dallas, TX

Long-distance communication reached Dallas in 1872, when telegraph lines arrived alongside the Houston & Central Texas Railroad, followed by the city's first telephone line in 1878. Two decades later the Southwestern Telegraph and Telephone Company built a toll relay office on this site in what was then the separate city of East Dallas, switching every long-distance call and linking the growing city to the wider world. By 1905 the little "toll building" had already been outgrown, a sign of how quickly the telephone had woven itself into everyday Dallas life.

Valley Spring, TX

O.C.J. Phillips arrived as the first settler in 1853, and the crossroads communities of Whistleville and Bugscuffle eventually merged into Valley Spring, which gained a post office in 1878. The little Hill Country settlement's proudest native son was James Field Smathers (1888–1967), credited as an inventor of the electric typewriter. It is a place where frontier origins and modern invention meet.

Nanticoke, PA · est. 1998

In 1913, the coal division of the D L & W Railroad built an unusual experiment in worker housing north of Nanticoke. Twenty-two identical poured-concrete double houses, arranged around a central park, drew on emerging modern design ideas to shelter miners of the Truesdale Colliery. The community was short-lived, abandoned by 1924, its bare concrete shells left standing.

Lincolnton, NC

Connie M. Guion, born near Lincolnton in 1882, became a pioneering woman in American medicine, earning a national reputation through nearly five decades of work at Cornell's medical clinic from 1922 to 1970. She broke barriers in a profession that had long excluded women, becoming one of the first women to hold major posts in academic medicine.

Conroe, TX

Conroe's telephone service began in 1899 inside Gilbert's Drug Store, where a local exchange grew out of a long-distance line running up from Houston. George Madeley soon bought the operation and ran it from his building on this site, and by the late 1920s it had grown into a busy switchboard staffed by toll, rural, and local operators. A dial system arrived in 1954, carrying the small-town exchange into the modern era.

Esmeralda County, NV

This building was the nerve center of Goldfield's communications from 1908 to 1963, during and after the great gold rush that briefly made Goldfield the largest city in Nevada. Between 1904 and 1910 the district boomed with more than 15,000 residents, four railroads, and mines producing millions. Flood in 1913 and a fire that leveled 53 downtown blocks in 1923—which this structure survived—hastened the town's long decline.

Dallas, TX

The inventor Robert Munger, already holding patents for improvements to cotton ginning, moved to Dallas in 1885 and used this building as the showroom for the machinery company he ran with his brother. After merging into the Continental Gin Company in 1900, the firm shipped cotton-gin equipment nationwide and remained a major Dallas business until 1962.

Grand Saline, TX

Land for this cemetery was deeded in 1886 by James Richardson, on whose grant the Corinth community had grown, with the oldest legible stone dating to 1874. Among those buried here are six known Civil War veterans and members of the founding families whose fieldstones and cedar trees still mark the earliest graves. The renowned aviator Wiley Post grew up in the Corinth community, and his parents, grandparents, and other kin — including his circuit-preacher grandfather, Rev. Thomas M. Post — rest here.

Merkel, TX

Cornelia Fort, born into an affluent Nashville family in 1919, discovered flying at twenty-one and within a week had logged over 2,000 miles; by 1941 she was an instructor. She was aloft with a student over Hawaii when Japanese planes struck Pearl Harbor, landing safely under fire, and soon joined Nancy Harkness Love's Women's Auxiliary Ferrying Squadron. On March 21, 1943, ferrying a BT-13 in formation toward Dallas, her plane was struck and went down in Mulberry Canyon — making her, records indicate, the first American woman pilot to die on active military duty.

San Angelo, TX

Dr. Boyd Cornick had survived tuberculosis himself, and in 1907 he built thirty cottages here to treat others with the methods he trusted: rest, a dry warm climate, and careful diet — a sharp break from period remedies like hot cane juice, honey and wine, or even arsenic. Patients traveled to San Angelo from across the country. Cornick went on to draft Texas' first sanitary code and helped bring about the state's first tuberculosis sanitarium at nearby Carlsbad.

Corvallis, OR

This tree began as a seed flown around the Moon during the Apollo 14 mission in 1971, part of an experiment to test whether the journey would affect its germination. The seeds returned to Earth and were grown into seedlings distributed as "Moon Trees," and this Corvallis tree is one of them. It stands as a quiet monument to space-age curiosity.

Catasauqua, PA · est. 1997

On the Fourth of July, 1840, Welsh ironmaster David Thomas fired up a furnace in Catasauqua that finally proved anthracite coal could smelt iron on a commercial scale. Earlier attempts had failed, but Thomas's hot-blast furnace for the Lehigh Crane Iron Company soon turned out 50 to 60 tons of pig iron a week, and the works grew to six furnaces before closing in 1930. The success helped shift American iron production away from charcoal and toward the hard coal of Pennsylvania's mountains.

Austin, TX

Completed in 1960, this three-unit building was commissioned by University of Texas English professor Thomas Cranfill as a home and studio for his partner, photographer and author Hans Beacham. It was designed by Harwell Hamilton Harris, a leading figure in American regional modernism who had directed UT's School of Architecture in the early 1950s. Its board-and-batten redwood siding, exposed concrete block, and light-filled open plan reflect Harris's belief in honest materials and a close bond between a building and its landscape.

San Mateo County, CA · est. 2006

On the morning of October 29, 1953, a British Commonwealth Pacific Airlines DC-6B bound from Sydney to San Francisco crashed into Kings Mountain, killing all nineteen people aboard — the deadliest aviation accident in San Mateo County history. Among the dead was William Kapell, one of America's most gifted young concert pianists, returning from an Australian tour. Though the exact cause was never resolved, the disaster fed into the tightening of aviation safety practices in the years that followed.

Meadville, PA · est. 1982

Formed from Allegheny County in 1800 and named for Colonel William Crawford, Crawford County grew up around Meadville, which in 1788 became the first permanent settlement in northwestern Pennsylvania. The county proved a seedbed of American firsts: the nation's first direct primary election was held here in 1842, and it became a cradle of both the oil industry and the modern zipper. Meadville anchored settlement in a corner of the state that was still wild frontier when the town was founded.

New Orleans, LA

Cucullu Row is the oldest intact row of houses in the French Quarter, six brick rowhouses built in 1828 for the merchant Simon Cucullu. But the corner's history runs deeper: here stood the 1730 celestial observatory of the architect-scientist Pierre Baron, followed by the Condé Market of 1782 and a fish market that grew until the great fire of 1788 swept the complex away. For nearly a century, from 1877 to 1970, Desporte Pharmacy served the neighborhood from these buildings.

Baltimore, MD

This plaque honors two very different Baltimore figures. Curt Richter, longtime head of the psychobiology laboratory at Johns Hopkins, did pioneering research on the body's internal "biological clock." Beside him is remembered Garry Moore, the genial host of 1950s and 1960s television variety shows.

Brady, TX

When World War II demanded thousands of new pilots, Brady mayor Harry Lamar Curtis secured his town's airfield as a national defense airport and won federal money to enlarge and pave it. A contract flight school relocated from Dallas's Love Field in 1941 and became Brady Aviation School, training more than 10,000 cadets under West Texas's clear, uncrowded skies before it closed in August 1944. The cost was not only financial: twenty-one cadets, six instructors, and a personnel officer died in training accidents here.

New Orleans, LA

Architect Nathaniel C. 'Buster' Curtis designed this house in 1963 for his own large family, and it stayed with the Curtises for half a century. Boldly modern in a city famed for its older styles, it was the first modernist house in New Orleans and the first work by the noted firm Curtis & Davis to reach the National Register. The city named it a landmark in 2010, and the National Register listing followed in 2014.

Village of Irvington, NY

In an age when a message could only cross the ocean as fast as a ship could carry it, the New York financier Cyrus W. Field spent years and several heartbreaking failures trying to lay a telegraph cable across the floor of the Atlantic. His persistence paid off in 1866, when a working line finally linked North America and Europe and let words leap between continents in minutes rather than weeks. Field made his home in the Hudson River village of Irvington, which honored its most famous resident by naming this road for him and dedicating it in December 1931.
