Ambrose Monell (1873 – May 2, 1921) was an American industrialist and military commander. He served as the first president of the International Nickel Company and was the namesake of the alloy known as Monel.[1]
Monell became an instructor at the School of Mines upon graduation.[7] He later joined Carnegie Steel Company as a metallurgical engineer and quickly rose through the ranks to become the company's Chief Metallurgical Engineer and assistant to the president by 1902. He was named one of the "Carnegie Boys" by Quentin R. Skrabec Jr. as having made an impact on American industry.[8] That year, he was named president of the newly incorporated International Nickel Company.[4]
Monell received a patent in 1906[9] on the manufacture of a nickel-copper alloy that became known as Monel alloy 400,[10] setting off a century of inventions in the alloy industry.[11] The alloy was named after Monell, but one l had to be truncated because at that time, family names were not allowed to be used as trademarks.[12]
In 1917, Monell resigned from the company to become a colonel on the staff of the American aviation services in France.[14] He died on May 2, 1921, at age 47.[14] The New York Times speculated that his death had to do with "strain of war" as he never returned to active business life and spent time at a sanitarium in Beacon, New York.[14][17]
Monell was identified by Harvard Business School as one of the "Great American Business Leaders of the 20th Century."[5]
He left an estate of $15,000,000 (equivalent to $442 million in June 2022 dollars) at the time of death.[20] His widow, Maude Monell Vitelsen, who later married Norwegian-American industrialist, G. Unger Vetlesen, established the Ambrose Monell Foundation in 1956.[4][21]
