William B. Ogden (1805-1877) was an American lawyer, entrepreneur, and politician who served as the first Mayor of Chicago in 1837. Born in New York State and educated at Columbia College, he moved to Chicago in 1835. After helping establish the city's initial governance framework as its first mayor, he became a pioneer in American railway development, co-founding the Illinois Central Railroad and the Chicago and North Western Railway. His contributions to Chicago's early growth and midwestern transportation infrastructure made him a foundational figure in American urban history.
