Sidekick status does Wallace an injustice. He was a visionary scientist in his own right, a daring explorer and a passionate socialist. This year's conferences and exhibitions marking a century since his death in 1913 (see go.nature.com/icpkp8) provide an excellent opportunity to reappraise his huge scientific legacy, which ranged from discovering natural selection to defining the term species, and from founding the field of evolutionary biogeography to pioneering the study of comparative natural history.
