About Eger V. Murphree

Eger V. Murphree Born Nov 3 1898 - Died Oct 29 1962

Method of and Apparatus for Contacting Solids and Gases Catalytic Cracking Patent Number(s) 2,451,804

Inducted into National Inventor's Hall of Fame in 1999

Eger Murphree, former president of Exxon Research & Engineering Co. (ER&E), was one of four Exxon inventors who created the fluid catalytic cracking process.

When ER&E’s’s first commercial cat cracking facility went on-line in 1942, the U.S. had just entered World War II and was facing a shortage of high-octane aviation gasoline.

Invention Impact

This new process allowed the U.S. petroleum industry to increase output of aviation fuel dramatically over the next three years. Fluid cat cracking also aided the rapid buildup of butadiene production. Butadiene was needed for ER&E’s process for making synthetic butyl rubber, a new technology vital to the Allied war effort.

Inventor Bio

Murphree was born in Bayonne, New Jersey, moving as a youngster to Kentucky. At Kentucky University, he graduated with undergraduate degrees in chemistry and mathematics in 1920, and then with a master’s degree in chemistry in 1921. After teaching high school and working for several years, in 1930 he joined what was then Standard Oil of New Jersey. From 1947 to 1962, he served as president.

Murphree, who was a member of the committee that organized the Manhattan Project, was widely recognized as a leader in the fields of synthetic toluene, butadiene and hydrocarbon synthesis, fluid cat cracking, fluid hydroforming, and fluid coking.


Eger Vaughan Murphree (November 3, 1898 – October 29, 1962) was an American chemist, best known for his co-invention of the process of fluid catalytic cracking.

He was involved in the early Manhattan Project as a member of the S-1 Uranium Committee.

He worked at Exxon (previously Standard Oil), and served from 1947 to 1962 as its VP of research and engineering.

Among his awards were the Perkin Medal in 1950.
