Amos Gager Throop was an American businessman and politician in Chicago, Illinois during the 1840s and 1850s. Most famously he was known for being a staunch abolitionist prior to the Civil War. He served as a Chicago alderman from the 4th Ward from 1849 through 1853. In Chicago, he lost two campaigns to be that city's mayor in 1852 and 1854. In both elections he was the nominee of the little-known Temperance Party, facing tough opposition from the Democratic Party. At the time of the Great Chicago Fire Throop was the City Treasurer of Chicago. He was instrumental in securing financing from New York to rebuild the wooden frontier town into a city of brick and mortar. Grateful Chicagoans renamed Main Street to Throop Street. Many years later and after moving to California, he was finally elected mayor—of Pasadena, California in 1888.
