Andrew Dickson White, the first President of Cornell University and himself a Bonesman, is said to have encouraged the formation of a "secret society" on campus. In the early years, the fraternities were called the "secret societies", but as the Greek system developed into a larger, more public entity, "secret society" began to refer only to the class societies, except for the Sigma Phi Society on campus. In the early twentieth century, Cornell students belonged to sophomore, junior, and senior societies, as well as honorary societies for particular fields of study. Liberalization of the 1960s spelled the end of these organizations as students rebelled against the establishment. The majority of the societies disappeared or became inactive in a very short period, and today, the four organizations which operate on campus are: Sphinx Head (founded in 1890), Der Hexenkreis (founded in 1892), Quill and Dagger (founded in 1893), and Order of Omega (founded in 1959). Dartmouth College Dartmouth College's Office of Residential Life states that the earliest senior societies on campus date to 1783 and "continue to be a vibrant tradition within the campus community". Six of the eight senior societies keep their membership secret, while the other societies maintain secretive elements. According to the college, "approximately 25% of the senior class members are affiliated with a senior society." The college's administration of the society system at Dartmouth focuses on keeping track of membership and tapping lists, and differs from that of Yale's, though there are historical parallels between the two colleges' societies. Dickinson College The Raven's Claw is an all-male senior honorary society at Dickinson College. It was founded in 1896, making it the first society unique to Dickinson College. Membership is limited to seven senior men who are selected by the seven previous members. The new members are chosen based on a variety of factors, these include campus leadership, a solid academic record, and athletic participation. New members are inducted through a "Tapping Ceremony" which is held on the "Old Stone Steps of Old West". The ceremony is traditionally conducted during the commencement weekend. They are called "claws" or "white hats", denoting the white caps they wear around campus to signify unity and loyalty. While the members of the group are known, the majority of their actions and traditions are concealed. The group prides itself in serving the Dickinson College and Carlisle, Pennsylvania communities through discreet service activities. The
