Choate House was built in 1867 by shoe manufacturer Samuel Baker in what is now Pleasantville, New York.
Choate added a wing as a private sanitarium to accommodate patients being treated for mental and nervous disorders.
His widow, wanting to turn the house over to her newly married son as a wedding gift, decided to live in the wing after moving it down the hill to its present location near Bedford Road.
The job of detaching the wing and moving it began on New Year’s Day 1909 and was completed in summer.
[clarification needed] The wing from Choate House is now a campus welcome center known as "Marks Hall."
