Henry Walter Bates, F.R.S., 1825-1892 and Alfred Russel Wallace, F.R.S., 1823-1913 These two Victorian naturalists, friends of Charles Darwin, have strong associations this part of Leicester. Bates was born a hundred yards or so from the site of this museum, and met Wallace when the latter was teaching at the Collegiate School just off the London Road. In 1844-1846, the two joined forces in our expedition to the Amazon in 1849. Wallace returning in 1852 & Bates in 1859, the year in which Darwin's “Origin of Species” was published. In 1858 Wallace discovered, independently of Darwin, the principal of natural selection as a key factor in evolution. Bates on the Amazon, discovered over eight thousand new species of animals, mostly insects, and it gave the first explanation of what is now known as Batesian Mimicry.
