Oliver K. Kelley

Olavi Koskenhovi "O.K." (28 June 1904 - 28 March 1987) immigrated from Finland in 1921 at age 17 and changed his name to Oliver K. Kelley (O.K. Kelley).[1] In 1940, Kelley became the engineer in charge of Automatic Transmission Development General Motors Corporation.[2]

Early Life and Career

Kelley was born in Salo, Finland, on June 28, 1904. He was educated at Chicago Technical College, where he received B.S. and M.E. degrees graduating in 1925. Kelley worked for Nash Motor, Milwaukee, as a draftsman. In 1929 Kelley began working for the G.M.C. Truck and Coach Division, where he worked on transmission problems, including air-shift synchromesh bus transmissions, hydraulic torque-converter bus transmissions, and infinitely variable friction drives. In June 1936, Kelley joined Earl A. Thompson's engineering group at the General Motors (GM) Engineering Department. This group combined a fluid coupling with a unique hydraulically controlled, automatically shifting 4-speed planetary transmission, introduced as an option on 1940 Oldsmobiles as Hydra-Matic, the world's first mass-produced fully automatic transmission.[3]

In 1957, after 17 years as head of the transmission group, Kelley became chief engineer at Buick Motor Division.[4] In 1960 Kelley went into GM's newly created Defense Systems Division as director of military vehicular systems[5] In 1966-1967 Kelley was the E. S. executive assistant to the V.P.)[6] Kelley Retired 1 Sept 1967[7] after 40 years with GM. Kelly died March 28, 1987[8] at the age of 82 in Bloomfield Hills, Michigan.

Notable Achievements

In 1940, upon the departure of Earl A. Thompson, Kelley became the head of the GM transmission group[9] where he was involved in developing, the Buick Dynaflow, Chevrolet Powerglide, Chevrolet Turboglide, and Buick Flight Pitch Dynaflow and Triple Turbine transmissions.
