William DeRyee
Corpus Christi, Nueces County, Texas
Marker Inscription
Chemist, geologist, and photographer William DeRyee was born as William Düry in Würzburg, Bavaria. He was educated at the Gymnasium and Lateinschule in Würzburg, then went on to study at the University of Munich. He participated in the 1848 uprising against King Ludwig I, but when it was suppressed, he left with other dissidents to settle in Tennessee. Here he married his wife, Dorothea Mylius from Saxony, in 1849. They had five children. He also changed his name to “DeRyee”. After establishing highly effective cottonseed mills, he gathered the attention of many copper mine operators and they hired him to investigate their mines. He and his family relocated to New Braunfels, where he developed and demonstrated new photography techniques alongside other German immigrants. During the Civil War, DeRyee served under The Confederacy as a state chemist to help develop materials for weapons and to find sources of nitrates for the military. He also invented smokeless explosives, and materials for marine torpedoes, but these did not see use in the Civil War. After the war, he moved to Corpus Christi, and opened the DeRyee and Bingham Drugstore. In 1867, after a yellow fever epidemic took his son, Emil, as well as physicians in town, William DeRyee developed remedies for the fever, including an effective antiseptic. He later represented Nueces County at the world cotton exposition in New Orleans in 1885. He went on to publish important geological research for the state. DeRyee is remembered as a major scientific leader in Texas history. (2015)

The Story
Born William Düry in Würzburg, Bavaria, this chemist, geologist and photographer fled to America after the failed 1848 uprising against King Ludwig I, remaking himself as William DeRyee. He built cottonseed mills, investigated copper mines, and pioneered photographic techniques among Texas's German immigrant community before serving the Confederacy as a state chemist developing nitrates and explosives. After the Civil War he opened a Corpus Christi drugstore and, during the 1867 yellow fever epidemic that killed his own son, developed remedies and an effective antiseptic.
Why it matters
DeRyee embodies the scientific ambition that European political refugees carried into 19th-century Texas, shaping the state's early industry, medicine and geology.
The story behind this marker
AI contextThe era
The middle decades of the 19th century sent a remarkable wave of educated Europeans across the Atlantic, and many of them landed in Texas. In 1848, revolutions swept the German states as reformers demanded constitutions, free speech, and an end to the old order of kings and princes. When those uprisings were crushed, thousands of the men who had risked everything for them — students, professors, chemists, engineers — chose exile over prison. They carried into America not just their politics but their learning, and Texas, with its German settlements like New Braunfels, became one of the places where that learning took root.
This was also an age when science was becoming intensely practical. Chemistry, geology, and the brand-new art of photography were leaping out of the lecture hall and into industry, medicine, and everyday commerce. A single well-trained mind could turn its hand to cottonseed milling one year, mineral surveying the next, and photographic experiments after that. The line between "scientist" and "inventor" and "entrepreneur" was gloriously blurry.
Into that world stepped a young Bavarian named William Düry, born in Würzburg and schooled in its classical academies before he studied at the University of Munich. Texas in his lifetime would pass through frontier statehood, a brutal civil war, and the fevers and hardships of Reconstruction — and he would leave his fingerprints on all of it.
People & events
William Düry was a man remade by history and by his own hand. Educated in Würzburg and Munich, he threw himself into the 1848 uprising against King Ludwig I of Bavaria. When it failed, he fled with other dissidents and settled in Tennessee — and there, in 1849, he began a new life in every sense: he married Dorothea Mylius, an emigrant from Saxony, started a family that would grow to five children, and changed his name to "DeRyee." A new country, a new name, a new man.
His talents refused to sit still. He built highly effective cottonseed mills, which drew the attention of copper-mine operators who hired him to investigate their mines — a chemist and geologist turned industrial consultant. Relocating to New Braunfels, he fell in with the community of German immigrants and developed and demonstrated new photography techniques among them, in the earliest, most experimental days of the medium.
When the Civil War came, DeRyee served the Confederacy as a state chemist, working to develop materials for weapons and to locate sources of nitrates for the military. He devised smokeless explosives and materials for marine torpedoes, though these did not see use in the war. Afterward he moved to Corpus Christi and opened the DeRyee and Bingham Drugstore. Then, in 1867, tragedy and duty collided: a yellow fever epidemic swept the town, killing physicians and taking his own son, Emil. DeRyee turned his chemistry against the disease, developing remedies and an effective antiseptic. Years later, in 1885, he represented Nueces County at the world cotton exposition in New Orleans, and he went on to publish important geological research for the state.
Its place in the American story
DeRyee's life is a compact history of how immigration built American science. The "Forty-Eighters" — the refugees of 1848 — are one of the great overlooked infusions of talent in the national story. Barred from remaking their homelands, they helped remake ours, seeding American towns with trained chemists, engineers, journalists, and teachers. DeRyee is that pattern in a single biography: a Bavarian revolutionary who became a leading man of science in Texas.
His career also shows how thoroughly a scientist of that era served whatever society he lived in — for better and for worse. He put his chemistry to work milling cotton, prospecting for copper, developing munitions for the Confederacy, and then, when fever came, fighting an epidemic that struck his own household. The same knowledge that could make explosives could also make an antiseptic. That breadth was typical of the 19th-century man of science, whose expertise was a tool the whole community — and the war — reached for.
And the yellow fever chapter connects to a national struggle that lasted the rest of the century. Epidemic fevers repeatedly devastated Southern and Gulf Coast towns, and doctors did not yet understand how the disease spread. Local practitioners improvising remedies and antiseptics were on the front line of a fight that medicine would not truly win until decades later.
If you visit
This memorial in Corpus Christi honors a life rather than a single event, so let it prompt you to imagine the several worlds one man moved through. Stand here and picture the sweep of it: a classical education in Bavaria, a barricade in a failed revolution, a name changed on American soil, and a working life that ran from cottonseed mills to a Gulf Coast drugstore counter.
As you read, notice how many different callings the marker gives him — chemist, geologist, photographer, miller, druggist, inventor. It's a useful reminder that the tidy job titles we use today didn't confine people in the 19th century. The most interesting figures of that age tended to be all of those things at once.
Corpus Christi wears its layered history along the bay and through its older streets, and DeRyee is one of the threads that ties the city to the wider immigrant story of Texas. Pair a visit here with the city's other 19th-century and maritime sites, and carry with you the human detail at the heart of it: that his most compassionate work — remedies and an antiseptic against yellow fever — came in the same epidemic that took his son.

Louis de Planque
Corpus Christi, TX
Prussian-born Louis de Planque came to the Rio Grande borderlands during the Civil War, when Confederate cotton pouring through Brownsville and Matamoros made boomtowns of both. He photographed Union and Confederate troops alike and weathered devastating hurricanes in 1867 and 1875 that twice destroyed his studios. Rebuilding each time, the flamboyant "Don Luis" spent his final decades as Corpus Christi's celebrated portrait photographer, training his wife Eugenie to carry on the business.
William Henderson Maltby
Corpus Christi, TX
Ohio-born William Henderson Maltby came to Corpus Christi in 1859 to help his brother publish the Ranchero, beginning a lifelong career in the frontier press. He served the Confederacy as an artillery officer until his battery was captured in 1863, survived the 1867 yellow fever epidemic that killed his first wife, and in 1877 co-founded the Corpus Christi Free Press, forerunner of the Corpus Christi Caller.
Jalufka-Govatos House
Corpus Christi, TX
James Jalufka, born in 1879 to Moravian Czech immigrants in Lavaca County, became a prominent South Texas cotton grower and a veteran of both the Spanish-American War and World War I. Around 1905 he built this house in Corpus Christi's "Old Irishtown" neighborhood. In 1944 it passed to Pete and Minnie Lee Govatos, part of the city's Greek community, before eventually being rescued from disrepair and moved to Heritage Park.
The Ranchero
Corpus Christi, TX
In 1859 circus-promoter-turned-civic-leader Henry Alonzo Maltby launched a four-page weekly newspaper in Corpus Christi that mixed editorials, poetry, recipes, and a register of local cattle brands. When war came, the Maltby brothers threw the paper behind the Confederacy; William was captured defending Mustang Island while Henry fled with his press to Mexico and then Brownsville, where a Union colonel briefly suppressed it. After the war the Ranchero kept up its defiant opposition to federal military rule until Maltby sold it in 1870, the year Reconstruction-era occupation of Texas ended.
