SANTA MONICA, Calif. — Famed ’60s anti-war activist Tom Hayden, whose name became forever linked with the celebrated Chicago 7 trial, Vietnam War protests and his ex-wife actress Jane Fonda, has died. He was 76. He died Sunday after a long illness, said his wife, Barbara Williams. He suffered a stroke in 2015.

Hayden, once denounced as a traitor by his detractors, overcame his past and won election to the California Assembly and Senate where he served for almost two decades as a progressive force on such issues as the environment and education. He was the only one of the radical Chicago 7 defendants to win such distinction in the mainstream political world.

He remained an enduring voice against war and spent his later years as a prolific writer and lecturer advocating for reform of America’s political institutions.
