Winganhauppauge
Also known as: Pasternack, Dr. Richard, House

Why it's listed
Overlooking Lower Winganhauppauge Lake in Islip, Long Island, this brick house was completed in 1941 for Dr. Richard and Elsa Pasternack. Architect Randolph Evans, known for the original Brooklyn College buildings, first sketched a Tudor Revival design, but after consultation with the owners it became a French Provincial residence. A two-and-one-half story center block with end chimneys sits between two curved single-story wings, all beneath a steep slate hipped roof. Steel casement windows, arched openings and red oak floors remain, along with a built-in audio system and the home laboratory spaces Dr. Pasternack used. He was Pfizer's first research director and secured over thirty patents, including work on vitamin C synthesis and purified penicillin production. The house, now on 3.9 acres of a former ten-acre property once belonging to the Knapp family, was listed for its architecture and its link to Pasternack. The period of significance runs from 1941 to 1965, when the Pasternacks sold the property.
Significance in brief: The nomination argues the house is significant under Criterion C as a mid-twentieth century French Provincial residence designed by Randolph Evans, known for the original Brooklyn College buildings. It is also significant under Criterion B as the most important surviving building associated with Dr. Richard Pasternack, Pfizer's first research director, whose work helped make the company a leading pharmaceutical producer.
