William Balfour Baikie was a surgeon, naturalist, linguist, writer, explorer, and government consul who played a key role in opening Africa to the Europeans. As an explorer he mapped and charted large sections of the Niger River system as well as the overland routes from Lagos and Lokoja to the major trading centres of Kano, Timbuctu and Sokoto. As a naturalist, major beneficiaries of his work included Kew Gardens and the British Museum for the rare and undiscovered plant and animal species and yet today he remains largely unknown. On 10th December, 1864 Baikie was on his way back to London and was living in his temporary quarters in Sierra Leone. There he worked to regain his health and to complete the various reports and publications expected by the Colonial and Foreign Offices. He had been away from England for seven years and living conditions in West Africa had caused his health to suffer. While his wife and children waited for his return 600 miles away in Lokoja, the city in Nigeria he had founded, his father waited for his return to Kirkwall, Orkney. Baikie would never return to his wife, nor ever see his father again. In two days, he would be dead and buried at Sierra Leone before his fortieth birthday. In his short life Baikie became such a hero among the Nigerian people 150 years ago that white visitors to the region today are still greeted warmly as 'Baikie'. After studying at University of Edinburgh he was assigned to the Royal Hospital Haslar where he worked with the noted explorers Sir John Richardson and Sir Edward Perry. Baikie's reputation as a naturalist, and the sphere of influence provided by Richardson and Perry, allowed him to enter the elite British scientific community where he also worked alongside the most famous naturalist of the time, Charles Darwin.
