The early career of G.H. Hardy

G.H. Hardy’s early career can be demarcated by his election to Trinity College in 1901 and by the beginning of his collaboration, in 1911, with J.E. Littlewood. During this time he wrote a textbook of enduring importance, established a reputation as an analyst, wrote five papers on set theory, contributed to the Educational Times and wrote several book reviews. He also began to play a role in political and social issues via his membership in the Apostles and the London Mathematical Society, as well as through his work to abolish the Tripos examinations. I will discuss Hardy’s mathematical work during this early period including his work on integration, his textbook, A Course of Pure Mathematics, and his five set theory papers.
