History.— Yonkers’ history goes back to 1639, when the so-called Keskeskeck Purchase, including approximately the present area of the city, was made from the Indians by the Dutch West India Company. Title passed through the New England Company in 1646 to Adriaen van der Donck, first lawyer and historian of New Netherland, from whose title (jonkheer) the city’s name is derived. Frederick Philipse (q.v.) acquired much of the van der Donck land in 1672 and succeeding years and built the first Philipse manor house here in 1682. In 1779, the third and last lord of the manor lost his lands because of loyalty to the crown during the American Revolution. Philipse Manor, a fine colonial building, now open to the public and administered by the New York State Education Department in collaboration with the American Scenic and Historic Preservation Society, houses the priceless Cochran Collection of 69 portraits of presidents of the United States, painted by Gilbert Stuart and other leading artists.
Yonkers was incorporated as a village in 1855 and as a city in 1872.
