Dacor is a former American manufacturer of scuba diving gear which was founded 1953 by Sam Davison Jr. in Evanston, Illinois as "The Davison Corporation", from which Dacor was coined by using the initial syllables, "Da" and "cor".[1][2]

Dacor was one of the five original United States diving gear makers: U.S. Divers, Healthways, Voit, Dacor, and Swimaster. Dacor merged with Mares. DaCor was patented by U.S. Patent 3,128,481 in 1955 by Sam Jr, founder and president. His brother, Donald Davison, was vice president and worldwide sales. After their deaths in the late 1980s, Sam's wife Joan became CEO of the company, and later sold to Mares.

Star Wars sound designer Ben Burtt used a Dacor scuba regulator to create the heavy breathing of the notorious antagonist Darth Vader.
