Kerry was also a member of the "skull and bones" society.
In his sophomore year, Kerry became the chairman of the Liberal Party of the Yale Political Union, and a year later he served as president of the union. Amongst his influential teachers in this period was Professor H. Bradford Westerfield, who was himself a former president of the Political Union.[30] His involvement with the Political Union gave him an opportunity to be involved with important issues of the day, such as the civil rights movement and the New Frontier program. He also became a member of Skull and Bones Society, and traveled to Switzerland[31] through AIESEC Yale.[32][33]
Under the guidance of the speaking coach and history professor Rollin G. Osterweis, Kerry won many debates against other college students from across the nation.[34] In March 1965, as the Vietnam War escalated, he won the Ten Eyck prize as the best orator in the junior class for a speech that was critical of U.S. foreign policy. In the speech he said, "It is the spectre of Western imperialism that causes more fear among Africans and Asians than communism and thus, it is self-defeating."[35]
Kerry graduated from Yale with a bachelor of arts degree in 1966. Overall, he had below-average grades, graduating with a cumulative average of 76 over his four years. His freshman-year average was a 71, but he improved to an 81 average for his senior year. He never received an "A" during his time at Yale; his highest grade was an 89.[36]
