Wallace Carothers

Seaford, Sussex County, Delaware

Marker Inscription

At this site in 1928, Wallace H. Carothers (1896-1937) began his pioneering studies into the chemistry of giant molecules. He soon confirmed that high molecular weight molecules consist of repeating units of simple molecules (monomers) linked together by chemical bonds to form long chains (polymers), as first proposed in 1920 by German chemist Hermann Staudinger. Carothers excelled at creating polymers, and his work quickly led to the E.I. du Pont de Nemours and Company's highly successful commercial production of neoprene, the first synthetic rubber made in the Unied States (1932), and nylon, the world's first totally synthetic textile fiber (1939).

The Story

At the DuPont laboratories, chemist Wallace Carothers began pioneering studies here in 1928 into 'giant molecules,' confirming that long chains of repeating units — polymers — could be built by design. His research led swiftly to neoprene, the first American synthetic rubber, in 1932, and in 1939 to nylon, the world's first fully synthetic textile fiber. Carothers laid the scientific groundwork for the age of plastics before his death in 1937.

Why it matters

Carothers's work launched the modern synthetics industry, and inventions like nylon transformed everyday life, wartime materials, and the American economy for the century to come.

Birthplace of Nylon (DuPont, 1939)

Seaford, DE · est. 1995

On the eve of World War II, a DuPont laboratory in Seaford turned a decade of fundamental chemical research into the world's first fully synthetic fiber. Spun from materials drawn out of coal, air, and water, nylon promised strength and elasticity to rival silk, and its December 1939 debut opened an age of synthetics that reshaped clothing, industry, and everyday life.

Submarine Monument

Anne Arundel County, MD

This monument marks one hundred years of the United States Navy's submarine service, a force that began at the dawn of the twentieth century when the Navy acquired its first commissioned submarine and grew into one of the most demanding and secretive branches of American sea power. From primitive early boats to the nuclear fleet of the Cold War and after, submariners have carried out their duty largely unseen, enduring cramped quarters, crushing depths, and long silent patrols. Standing in Maryland near the heart of Navy tradition, the memorial deliberately widens its dedication beyond the sailors themselves to the families who wait ashore and the support personnel who keep the boats at sea.

Aberdeen Proving Ground Memorial

Aberdeen, MD

Aberdeen Proving Ground opened in 1917 as the U.S. Army's premier weapons and ordnance testing site on the Chesapeake Bay, soon joined by the neighboring Edgewood Arsenal, which became the center of the nation's chemical warfare research. For more than a century the soldiers, civilian scientists, and contractors stationed here have tested artillery, armor, and munitions—demanding and often dangerous work that has cost lives across generations. This monument gathers all of them—uniformed and civilian alike—into a single act of remembrance.

Milestone in Radio History

Charles County, MD

On a small island in the Potomac in December 1900, Reginald Fessenden and his assistant Frank Very did something no one had done before: they sent understandable human speech through the air on radio waves, from one tall mast to another. Until that moment wireless meant only the dots and dashes of Morse code; here, the spoken word itself first traveled without wires. It was the quiet beginning of everything from broadcast radio to the mobile phone.
