Sir William Peterson was Principal of McGill University for a period of twenty-four years, one quarter of its century of life. During that time many honours came to him. He occupied the presidency of many learned societies; he was knighted in 1915; he received honorary degrees from the leading universities of Britain, America and Canada; he was Chairman of the Board of Trustees of the Carnegie Foundation for the Advancement of Teaching; he won great distinction as a scholar and a writer. It would be unwise here to attempt to estimate the significance of his work as Principal of the University. We are perhaps too close to judge it with correctness or with justice. The McGill he left in 1919 was not the McGill he found in 1895. In the intervening years its development on the sure foundations that had already been laid was extraordinary and unprecedented for a university. Among the external evidences of growth during that time are the McGill Union, the centre of student activities; the Conservatorium of Music, with courses leading to the degree of Bachelor and Doctor of Music; the establishment of a Department of Dentistry, now grown to the stature of a Faculty; the acquisition of the Joseph property at the southwest corner of the Yard, and the new Molson and Law properties, consisting of 25 acres, the site of the Molson Stadium, and of the gymnasium and student residences of the future; the new Medical building; the establishment and development of the Graduate School, and of the Departments of Commerce, Social Service and Physical Education, and above all, the addition of Macdonald College with its vast acres at Ste. Anne de Bellevue, where the work of the Faculty of Agriculture, Household Science and the training of teachers is carried on. In these twenty-five years the number of students more than doubled. Financially, too, there was a change. In 1895 endowments amounted to over a million and a half of dollars, in 1919 they were over twelve millions, a sum to which the citizens' response to the appeal for funds in 1911 largely contributed; the income in 1895 was two hundred thousand dollars and the disbursements one hundred and eighty thousand; in 1919 the income and disbursements each amounted to approximately one million dollars. In addition to these visible evidences of progress many new and improved courses were established; the teaching staff was greatly increased, and the reputation of the University was enhanced at home and abroad. Externally and internally the newer and greater McGill bears testimony to the energy and determination of Sir William Peterson during his twenty-four years' occupancy of the Principalship. With the criticisms of his administration--that as Principal Sir William was an Imperialist first and afterwards a Canadian, and that in making professorial appointments he did not often consider Canadian scholars, with at least equal qualifications--we are not here concerned.
