James Renwick Jr. designed some of the most important buildings of nineteenth-century New York and Washington, including Grace Church, the Smithsonian Institution Building, St. Patrick's Cathedral, and the Corcoran Gallery.

The Smallpox Hospital was one of his earliest major commissions. He was just 35 when he began designing it.

In 1853, Archbishop John Hughes engaged Renwick to design St. Patrick's Cathedral on Fifth Avenue. The following year, Renwick began designing the Smallpox Hospital on Blackwell's Island.
