Leroy Randle "Roy" Grumman (4 January 1895 – 4 October 1982) was an American aeronautical engineer, test pilot, and industrialist. In 1929, he co-founded Grumman Aeronautical Engineering Co., later renamed Grumman Aerospace Corporation, and now part of Northrop Grumman.〔("The Embattled Farmers." ) ''Time'', 11 September 1944.

==Early life==
Born in Huntington, New York, Grumman's forebears had Connecticut roots and owned a brewery. When he was a child, his father, George Tyson Grumman, owned and operated a carriage shop and later worked for the post office.〔Treadwell 1990, p. 19.〕〔Fetherston, Drew. "Raising Grumman: How Leroy Grumman and Jake Swirbul built a high-flying company from the ground up." ''Newsday,'' 19 April 1998. Retrieved: 22 March 2009.〕 From an early age, "Red Mike" (a nickname he gained because of his red-blond hair)〔 demonstrated an interest in aviation, and in his 20 June 1911 high school salutatory〔 address at Huntington High School, Grumman predicted that "()he final perfection of the aeroplane will be one of the greatest triumphs that man has ever gained over nature."〔Kessler 1985, p. 47.〕〔Skurla and Gregory 2004, p. 26.〕
Grumman went on to earn a Bachelor of Science degree in mechanical engineering from Cornell University in 1916.〔 He landed his first job in the engineering department of the New York Telephone Company. After the United States entered World War I, he enlisted in the U.S. Naval Reserve in June 1917 as a machinist's mate, 2nd class, and was sent to Columbia University for a course on "subchaser" engines.〔〔〔Thruelsen 1976, p. 19.〕
