Lynn “Buck” Compton, one of the World War II soldiers from Easy Company who was chronicled by historian Stephen Ambrose and portrayed by actor Neal McDonough in HBO’s miniseries Band of Brothers, died Saturday, according to the Los Angeles Times. The former Los Angeles deputy district attorney and California Court of Appeals judge had suffered a heart attack last month. He was 90 years old.

When Compton was 22 years old, he was one of the Americans who parachuted into Nazi-occupied France on D-Day, June 6, 1944. By the time the fighting ended, he’d earned a Silver Star and a Purple Heart for his service.

Before the war, he’d been a starter on the UCLA football team that played in the Rose Bowl in 1943 and was a star baseball player. After the war, he became an L.A. cop and a respected attorney. In 1969, he was one of the lawyers who successfully prosecuted Sirhan Sirhan for the assassination of Robert Kennedy. He was appointed by then-governor Ronald Reagan to the Court of Appeals in 1970 and sat on the bench for 20 years. In 2008, he co-authored the book, Call of Duty: My Life Before, During, and After the Band of Brothers.

His wife, Donna, died in 1994, and he is survived by two daughters and four grandchildren.
