Bill Haast (December 30, 1910 – June 15, 2011) was the owner and operator, from 1947 until 1984, of the Miami Serpentarium, a tourist attraction south of Miami, Florida, where he extracted venom from snakes in front of paying customers. After closing the Serpentarium, he opened the Miami Serpentarium Laboratories, a facility in Punta Gorda, Florida that produced snake venom for medical and research use. Haast extracted venom from venomous snakes from the time he was a boy.
