William P. Henszey (December 24, 1832 – March 23, 1909) was an American industrialist, partner and Chief Engineer of the Baldwin Locomotive Works. He was a notable designer of locomotive engines.
Henszey joined Baldwin in 1859 as a draftsman, served as an engine designer and as Chief Engineer, and became a partner in 1870.[1][2][3] He eventually owned a 20% share in the firm.[1] Because his ownership share was so large, at his death the other partners decided to reorganize the firm as a joint stock company.[1]
Henszey as born in Philadelphia.[1] He married in 1857 to Anna B. Hitchcock.
Henszey's mansion, Red Leaf, on 6 acres in Wynnewood, Pennsylvania, designed by Furness & Evans, was his family home from 1881 until his death in 1909.[4] The original manor house burned in the 1890s, and was replaced with a home in Tudor Revival style about 1900. The mansion was converted into apartments in 1946.[5]
