Frederick Herbert Sill (1874 – July 17, 1952) was an American Episcopalian priest and educator.
He graduated from Columbia University in 1894 and from General Theological Seminary in 1898, the same year he was ordained.
In 1900, he became a monk of the Order of the Holy Cross and founded the Kent School on the Housatonic River in 1906.
[4] He promoted the philosophy of self-help and stewardship by asking students, many of whom scions of prominent families, to participating in housework or help with farming to raise produce for the school.
Sill was the coxswain of the Columbia varsity crew of 1895 that won the first Intercollegiate Rowing Association regatta at Poughkeepsie, New York, and he coached the crew team of Kent School, leading it to victory in regattas across New England.
