LOS ANGELES — Murray Fromson, a longtime CBS News correspondent and former Associated Press reporter known for his work during the Korean and Vietnam wars, has died at age 88.

Fromson, who had suffered from Alzheimer’s disease for several years, died in his sleep Saturday morning in Los Angeles, said his son, Derek Fromson.

During his 35-year career in broadcast news, Murray Fromson covered the Vietnam War and the fall of Saigon, the armistice talks in Korea, the end of the U.S. occupation in Japan, and the Apollo space program.

Fromson worked for the Associated Press for several years in the 1950s before he went to work at NBC News and then became a longtime CBS News correspondent.

He also covered two presidential elections, three summit meetings between Richard Nixon and Leonid Brezhnev of the former Soviet Union, and “Bloody Sunday,” a day of racial violence in Selma, Alabama, in 1965.

Fromson and his colleagues at CBS News also won two Overseas Press Club awards for reporting on the fall of Saigon.

He was a founding member of the Reporters Committee for Freedom of the Press, a nonprofit organization that provides legal representation and resources to protect the rights of journalists.

“I’m very proud of the fact that committee has lasted almost 50 years and we have defended journalists all over the country,” Fromson said during a 2015 interview for the University of Southern California’s Living History Project. “It is one of the proud moments of my life.”

Fromson also served as a deputy campaign manager in 1978 when California Gov. Jerry Brown, a Democrat, was vying for his second term.

He joined the faculty of the University of Southern California in 1982 and later served as the director of the university’s Annenberg School for Communication and Journalism.

Fromson also served as a judge for the Pulitzer Prizes in journalism in 2003 and 2004.
