John Notman was a Scottish-born American architect and landscape architect based in Philadelphia. He designed buildings, cemeteries, churches and country estates in the Mid-Atlantic region of the United States and helped popularize Italianate architecture in the United States.

The Italianate style was a distinct 19th-century phase in the history of Classical architecture. Like Palladianism and Neoclassicism, the Italianate style combined its inspiration from the models and architectural vocabulary of 16th-century Italian Renaissance architecture with picturesque aesthetics. The resulting style of architecture was essentially of its own time. "The backward look transforms its object," Siegfried Giedion wrote of historicist architectural styles; "every spectator at every period—at every moment, indeed—inevitably transforms the past according to his own nature."
