Loran Arthur De Wolfe
The first M.Sc. in Geology was awarded to Loran Arthur De Wolfe, in April, 1903. He spent his whole life in education, at the Nova Scotia Teacher's College and in government, and was a major player in the development of the educational system of the province. I have not been able to find the title of this thesis, but in 1904 he published a lengthy paper on "The Structure and succession at North Sydney and Sydney Mines, C.B." which may be derived from that thesis.
According to a list of graduates in the calendar for 1907-08, DeWolfe received the second Master of Science degree awarded by Dalhousie. The first, in 1898, went to Ebenezer H. Archibald for work in Physics. He went on to Harvard and thence to the University of British Columbia, where he was head of the Chemistry department from 1920 to 1927.
