LSE Students' Union made international headlines in the late 1960s during the well-documented LSE student riots in 1966–67 and 1968–69. In 1967, David Adelstein, president of the Students' Union, and Marshall Bloom, president of the Graduate Students' Association (that then existed as a parallel Union for postgraduates), were suspended from the School for taking part in a protest against the appointment of Walter Adams as Director of the School, in which a porter died of a heart attack. Adams had previously been in Rhodesia and was accused of complicity in the regime's white minority rule. The suspensions were reversed five days later, after students began a hunger strike in opposition to the move. An American citizen, Bloom committed suicide in 1969 when he was called up to fight in Vietnam.
