The Society of the Claw was a Princeton University organization created by the Class of 1894. Society members pledged to attend Princeton reunions annually, either for five-year periods or during their lifetimes. Members received a charm for their watch chains which included a genuine tiger claw to remind them of their pledge. The Society's principal long-term accomplishment was the proposal and subscription of the bronze stars placed on university dormitories in memory of World War I war dead.
