John O'Fallon (November 17, 1791 – December 17, 1865) was a businessman, philanthropist, and military officer, a nephew of the explorer William Clark. During the 19th century he rose to become the wealthiest person in St. Louis, Missouri.[1] The cities of O'Fallon, Illinois and O'Fallon, Missouri are named after him.[2] In 1857, he donated over $1 million to establish the O'Fallon Institute at what is now Washington University in St. Louis.[3]
