Van Ellis Huff (1894 – 1987) was a University of Florida trained engineer who popularized residential use of a combination jalousie window.
Drawing inspiration from common wooden slat windows he'd become familiar with in the Bahamas, he designed a hand-cranked glass, aluminum and screen window version that found widespread use in temperate climates before the advent of air conditioning.
[1] Fitted also in cooler regions in porches and sunrooms, jalousies became a multimillion-dollar industry and the company Huff had built to manufacture them prospered.
However, amid complaints over underbidding and his salesmen's tactics, Huff sold his share in 1956 and retired.
[1] Huff is sometimes referred to inaccurately as the "inventor" of the jalousie window.
