Life and career
Cassidy was born in New York City, the child of Irish immigrants. The family moved to Philadelphia shortly afterwards. His father died when he was ten.
Cassidy attended Central High. Upon graduating, he studied law in the offices of Benjamin H. Brewster, and was admitted to the bar in 1849. He was immediately successful, and proved popular with the Moyamensing Hose Company, and was elected to the state House for the 1851 term. In 1852, Cassidy was elected Solicitor for the District of Moyamensing. By 1856, Cassidy was already considered a local political boss, and his influence helped elect Richard Vaux city mayor. He himself ran for District Attorney against William B. Mann, originally winning and inducted into office, but later losing after a judge ruled for Mann.
During the Civil War and afterwards, he was a staunch supporter of Union and federal coercion. He became a local leader of Democratic party politics. His support helped Robert E. Pattison become Governor—the state's only Democratic governor between the Civil War and the Great Depression—and Pattison in turn appointed Cassidy state Attorney General.
