Hayden became one of the more "famous" members of the Chicago Seven in large part due to his love life: he was married to Jane Fonda from 1973 to 1990. After being imprisoned for taking part in the Freedom Rides, he wrote the manifesto for the Students for a Democratic Society, a student leftist activist group. He was a vocal anti-war activist and a prolific author as well, and later served in both houses of the California state legislature: in the State Assembly from 1982 to 1992, and in the State Senate from 1992 to 2000. He died in 2016.
