In 1854 he joined the
Ethnological Society of London because of his interest in racial differences and from 1859 to 1862 was the honorary secretary. However many members of this society disliked his attacks on humanitarian and missionary societies and the anti-slavery movement. So in 1863, with the help of the explorer
Richard Burton, he set up the
Anthropological Society of London, becoming its first president. His paper ''The Negro's place in nature'' was greeted with boos and hisses when given at the
British Association meeting in 1863 because of its defence of slavery in the
Confederate States of America and belief in the
plurality of the human species. He established the
Anthropological Review as the organ of the society and by 1867 the membership of the Society had reached 500. However, by 1867 allegations by one of the members
Hyde Clarke of financial irregularities in his running of the society caused his temporary resignation as president, though he returned in 1868 when Clarke was expelled. This took a toll on his health and in 1869 he died of an inflammation of the brain. The society shortly afterwards started discussions to merge with the Ethnological Society. == Death ==
