Charles D. Gambrill FAIA (1834–1880) was an American architect in practice in New York City from 1860 until his death in 1880.
In Snell's studio Gambrill worked alongside several others, including his former classmate Henry Van Brunt.
In 1857 Gambrill and Van Brunt left Boston for New York City, where they joined the atelier of Richard Morris Hunt, the first American architect to attend the Beaux-Arts de Paris.
[2][3] In October of the same year Gambrill formed a new partnership with Henry Hobson Richardson, also a Harvard graduate and the second American architect to study in Paris.
Though not in debt, Gambrill had suffered personal financial losses and had been in poor physical and mental health for some time, having threatened suicide in the past.
