Alphonse [Alfonso] Arcelin (1936 - 17 August 2009) was a Haitian doctor, anthropologist, and human rights defender who resided in Banyoles, Catalonia, Spain. In the early 1990s, he initiated a lone campaign to demand the removal and repatriation of the taxidermied body of an African man, who had been on display at Darder Museum of Nature and Science (Spain) since the early 20th century. In the lead up to the 1992 Olympics, which were set to take place in Barcelona, he sent letters to Spanish politicians, the press, international bodies and to heads of African governments to raise awareness of the indignity of the display, and the deragotary naming of the man as ""El Negro de Banyoles"". He is quoted as saying “How can the world come here to honor unity, when a Black man’s body lies dishonored in a museum nearby?”. His efforts precipiated a worldwide call for the display to removed, and triggered threats to boycott the Olympics if action was not taken. Following the removal of the display, Arcelin continued to call for the repatration of the unknown man's remains to his continent of origin, in the process enduring racism, isolation, and personal attacks in Catalonia. However, in 2000, his efforts, along with those of Federico Mayor Zaragoza (UNESCO) and Kofi Annan (United Nations) bore fruit, with one of the first human ancestor repatriations to Africa.
