Wallace Alfred Russel Wallace
1823 - 1913
Wallace was an accomplished field collector. Despite the disastrous fire that destroyed his Amazon treasures, he continued collecting, amassing 125,000 specimens during his eight years in the Malay Archipelago (modern Malaysia, Borneo Indonesia and New Guinea).

He forced the theory of evolution by natural selection into the limelight when he wrote to Darwin on the subject, and presented the theory jointly with him in 1858. He also developed a theory of biogeography.
