John Thomas Wilder was born in Hunter, New York, in the Catskill Mountains and moved west at age 19 to begin a career as a millwright in Columbus, Ohio. By 1857, he had settled in Indiana, where he founded a successful iron foundry. Wilder became nationally known for his hydraulic inventions, including a patented water wheel, and for designing and building mills.
When the Civil War began, Wilder organized an artillery company and cast two cannons in his own foundry before being commissioned as captain of the 17th Indiana Infantry. He quickly rose to colonel and, in February 1863, took command of the mounted infantry unit that became famous as Wilder's Lightning Brigade. (See the previous post for more about the brigade's history and its connection to Tunnel Hill.)
After the war, Wilder settled in Rockwood and later Chattanooga, Tennessee, where he operated blast furnaces, founded an ironworks company, and manufactured railroad rails. He served briefly as mayor of Chattanooga before returning to business full time.
Wilder died in Jacksonville, Florida, on October 20, 1917, while on his annual winter vacation. He is buried in Forest Hills Cemetery in Chattanooga, and Wilder Tower at Chickamauga and Chattanooga National Military Park honors him and the stand made by his Lightning Brigade during the Battle of Chickamauga.
