 As a partisan of Jevonianism, Edwin Cannan is perhaps best known for his logical dissection and destruction of Classical theory in his famous 1894 tract "A History of the Theories of Production and Distribution".Although Cannan had personal and professional difficulties with Alfred Marshall, he was still "Marshall's man" at the LSE from 1895 to 1926.During that time, particularly during his long stretch as chairman after 1907, Edwin Cannan shepherded the LSE away from its roots in Fabian socialism into tentative Marshallianism.
