Herbert Earl Grier

Herbert Earl Grier (July 3, 1911 — March 17, 1999) was an American electrical engineer. His professional activity in the 1930s to 1940s included co-invention, with Harold Edgerton and Kenneth Germeshausen, of a miniature stroboscope and handheld flash. During World War II, Grier built a firing mechanism that was used in the Fat Man bomb.

After he, Edgerton and Germeshausen created EG&G in 1947, Grier was involved in nuclear tests including Operation Sandstone and Operation Ranger. In EG&G, Grier was the president until 1976, and served as a consultant from 1983 to 1994. Apart from electrical engineering, he took part in NASA safety boards, between the 1970s and 1980s, that assessed Skylab and the preparation of the first Space Shuttle. He was awarded the NASA Distinguished Service Medal in 1985, andin 1989 the National Medal of Science.

Grier was born on July 3, 1911 in Chicago, Illinois. At the age of eleven, Grier and his family left Chicago to live in New York City. For his post-secondary education, Grier graduated with a Bachelor of Science and Master of Science from the Massachusetts Institute of Technology in the early 1930s.

Grier started his career as an electrical engineer for MIT from 1934 to 1947. During this time period, Grier co-invented a miniature stroboscope alongside Harold Edgerton and Kenneth Germeshausen in 1934. Years later, Grier and his colleagues created a Kodak handheld flash for newspaper photographers in 1940. While working on aerial photography for Edgerton during World War II, Grier joined the Manhattan Project and built the firing mechanism used in the Fat Man bomb.

After forming EG&G with Edgerton and Germeshausen in 1947, Grier was involved in nuclear testings between the late 1940s and early 1950s. These included Operation Sandstone, Operation Ranger and Operation Ivy. With EG&G, Grier was the company's president until 1976 and was a consultant from 1983 to 1994. Other executive roles Grier had were president of GEC Geonuclear Company from 1965 to 1983 and chairman of Reynolds Electrical & Engineering Company from 1969 to 1971. Outside of electrical engineering, Grier was selected for a 1973 NASA advisory board on safety that reviewed Skylab. He also led a 1980 safety committee that assessed the preparation of the first NASA Space Shuttle.

Grier was a recipient of the NASA Distinguished Service Medal in 1985 and the National Medal of Science in 1989.

Grier died on March 17, 1999 in La Jolla, California. He was married and had three children.
