In January 1896 Reeves left New Zealand for London, where he was
Agent General (1896–1905) and
High Commissioner (1905–08). While he was in Britain Reeves became a friend of a number of left-wing intellectuals, such as
George Bernard Shaw,
H. G. Wells, and
Sidney and
Beatrice Webb, all leading members of the
Fabian Society. He was also a member of the
Coefficients dining club of social reformers. Reeves became Director of the
London School of Economics (1908–19) and President of the
Anglo-Hellenic League (1913–25). He also headed the committee organising the
First Universal Races Congress in London in 1911. Finally, he was chairman of the board of the
National Bank of New Zealand from 1917 to 1931. Reeves's more influential writings include his history of New Zealand,
The Long White Cloud (1898) and
State Experiments in Australia and New Zealand (1902). He also published a number of poems, such as "The Passing of the Forest" and "A Colonist in his Garden". Reeves married
Magdalen Stuart Robison in 1885. She was a
feminist who later joined the Fabian Society. They had two daughters, the feminist writer
Amber Reeves (born 1887) and Beryl (born 1889), and one son, Fabian Pember Reeves (1895–1917), who was killed in the
First World War, aged 21, as a Flight Lieutenant in the
RNAS. Reeves three times declined offers of a
knighthood. ==Works==
