Alexander Manoogian (; June 28, 1901 – July 10, 1996) was an Armenian-American industrial engineer, businessman, entrepreneur and philanthropist who spent most of his career in Detroit, Michigan. He was the founder of the Masco Corporation, which in 1969 was listed on the NYSE (XNYS:MAS). In 1954, he patented and brought to market the first successful washerless ball valve faucet, the Delta faucet, named for the faucet cam shaped like the fourth letter of the Greek alphabet. He and his wife Marie donated the Manoogian Mansion to the city of Detroit, which uses it as the official residence of the Mayor of Detroit. In addition to donations to local universities, the Manoogians donated substantial amounts of money to churches, educational institutions and charities of the Armenian Diaspora to preserve and continue their culture. Career Arriving in Bridgeport, Connecticut, in 1920, Manoogian began working as a machinist. He also worked for short periods in Rhode Island and in Massachusetts. In time, he was joined by his parents, two brothers and two sisters. Manoogian and his family moved to Detroit, Michigan, in 1924, attracted to opportunities in the booming auto industry. After gaining more experience, in 1929 he founded the Masco Screw Company, later known as Masco Corporation.
