Military

Corman was a cadet officer at UCLA with the Reserve Officer Training Corps,^[1] and he was made a second lieutenant in the U.S. Marine Corps in June 1943.^[2]

In 1944, he told of the death of a Japanese soldier he witnessed in the Mariana Islands while his Marine unit was guarding a food supply. The Marines held their fire until the Japanese "began pawing over the [food] in the darkness, and then opened fire." One Japanese "fell wounded over a crate of salmon cans. His companions fled."^[3] Corman continued:

Suddenly we heard the tap of a grenade. We ducked into our foxholes just before the explosion and were unhurt. In the morning we found the Jap had decapitated himself. In his wallet was a magazine clipping of a picture of Japanese-American soldiers fighting with United States forces in Italy.^[3]

City Council

In 1957 Corman, supported by labor and Democratic votes, was elected to a four-year term represent Los Angeles City Council District 7, over Kay Bogendorfer, a Republican.^[4] In that year, this newly established San Fernando Valley district was bounded on the south by Riverside Drive on the east by Coldwater Canyon and Woodman avenues and on the west generally by Balboa Boulevard. It had been moved from Downtown Los Angeles after Councilman Don A. Allen was elected to the State Assembly.^[5] Corman did not finish his term, being elected to Congress in 1960.

Congress

Representative Corman and other members of the House Committee on Science and Astronautics visit the Marshall Space Flight Center on March 9, 1962 to gather first-hand information of the nation's space exploration program.

"In with President Kennedy and out with President Carter," he would say after he left the United States Congress. He served in the House of Representatives from 1961 to 1981.^[6] Corman served as the chair of the Democratic Congressional Campaign Committee from 1976 to 1981. Until Sean Patrick Maloney’s defeat in 2022, Corman was the most recent chairman of the DCCC to lose re-election.^[7]

Corman voted in favor of the 24th Amendment to the U.S. Constitution,^[8] the Civil Rights Act of 1964,^[9] the Voting Rights Act of 1965,^[10] the Medicare program,^[11] the Civil Rights Act of 1968,^[12] and alongside fellow Democrat Martha Griffiths and Republicans Charles Adams Mosher and Ogden Reid, was one of the main co-sponsors of the House version of Ted Kennedy's Health Security Act universal healthcare bill in 1971.^[13]

In 1980, Corman was narrowly defeated for re-election by Los Angeles School Board member Bobbi Fiedler.^[14]

Later career

After his Congressional service, he opened a lobbying firm, Corman Law Offices, in Washington, D.C., with a partner, William Kirk. Their clients included MCA Inc., American Newspaper Publishers Association and National Structured Settlements Trade Association.^[15] The firm merged with Silverstein & Mullens in January 1990. Corman represented Texas Air Corporation president Frank Lorenzo in his contested takeover of Continental Airlines. He stopped representing the National Committee to Preserve Social Security and Medicare because of its "high-pressure fund-raising methods and alarmist pronouncements."^[16]

In 1985 he was elected president of Americans United for Separation of Church and State.^[17]
