Charles Yerkes

Charles Tyson Yerkes (/jɜːrkiz/ YUR-keez; June 25, 1837 – December 29, 1905) was an American financier, born in Philadelphia. He played a major part in developing mass-transit systems in Chicago and London.

Yerkes was born into a Quaker family in the Northern Liberties, a district adjacent to Philadelphia, on June 25, 1837. His mother died of puerperal fever when he was five years old and shortly thereafter his father was expelled from the Society of Friends for marrying a non-Quaker. After finishing a two-year course at Philadelphia's Central High School, Yerkes began his business career at the age of 17 as a clerk in a local grain brokerage. In 1859, aged 22, he opened his own brokerage firm and joined the Philadelphia .

By 1865 he had moved into banking and specialized in selling municipal, state, and government bonds. Relying on his bank president father's connections, his political contacts, and his own business skill, Yerkes gained a name for himself in the local financial and social world. He was on the verge of entering Philadelphia society when disaster struck.

While serving as a financial agent for the City of Philadelphia's treasurer Joseph Marcer, Yerkes risked public money in a colossal stock speculation. This speculation ended calamitously when the Great Chicago Fire sparked a financial panic. Left insolvent and unable to make payment to the City of Philadelphia, Yerkes was convicted of larceny and sentenced to thirty-three months in the dreaded Eastern State Penitentiary, notorious for its system of solitary confinement.
