I am compiling a list (with images) of all honours received by Wallace for his work. The list is incomplete at present.
1868 (30 November): Royal Medal of the Royal Society. (Awarded "For his labours in practical and theoretical zoology". He was nominated by T. H. Huxley)
1870: Gold Medal, Société de Géographie.
1890 (1 December): Darwin Medal of the Royal Society. (Awarded "For his independent origination of the theory of the origin of species by natural selection". Wallace was the first recipient of this medal).
1892 (23 May): Founder's Medal of the Royal Geographical Society. (Awarded "...in recognition of the high geographical value of his great works, 'The Geographical Distribution of Animals,' 'Island Life,' and 'The Malay Archipelago.'")
1892 (24 May): Gold Medal of the Linnean Society (now known as the Linnean Medal).
1908 (1 July): gold Darwin-Wallace Medal of the Linnean Society of London. (Wallace was the first recipient of this medal, and his was the only gold version ever made).
Wallace's Darwin-Wallace medal.
1908 (30 November): Copley Medal of the Royal Society. (Awarded "On the ground of the great value of his numerous contributions to natural history, and of the part he took in working out the theory of the origin of species by natural selection." This is the highest award of the Royal Society.)
1908 (14 December): Order of Merit. (The order has been described as "quite possibly, the most prestigious honour one can receive on planet Earth." There may be only 24 living individuals in the order at any given time, not including honorary appointees, and new members are personally selected by the reigning monarch.)
1879 (28 July): Freedom of the City of London.
1882 (29 June): LL.D. (Doctor of Laws) from Trinity College, University of Dublin. (On the recommendation of Rev. Samuel Haughton, senior lecturer in geology)
