Dr. Thomas Alexander Lambie (1885- 14 April 1954) was a missionary medical doctor noteworthy for becoming an Ethiopian citizen, being responsible for several early medical efforts in Ethiopia (including the founding of two hospitals). He also worked as a medical doctor in Sudan, Nigeria and Palestine, where he died.
Dr. Lambie was born in Pittsburgh, United States. He worked as a missionary with his family in Sudan among the Nuer and Anuak people, and then sailed up the Baro River into Ethiopia in 1918, becoming the first American missionaries in Ethiopia. He began work in Sayo, Welega, and Gore in Illubabor Province.
Dr. Lambie removed a small beetle that had crawled into Governor Ras Tessema Nadew's ear that was causing great pain. Ras Nadew's gratitude led him to write a letter of commendation and an introduction to the prince regent, Ras Tafari (later Emperor Haile Selassie). When the Lambie family traveled to Addis Ababa, Ras Tafari requested that Dr. Lambie build a hospital there, offering him a tract 12 acres in size at Gullele outside the city. Upon his return to the United States, Dr. Lambie approached his board for help with this endeavor; although they recognized the need for a hospital the board was unable to provide him with the necessary funds, which led Lambie to embark on a fund-raising tour of his country. It was while visiting a small town in Ohio that he encountered W.S. George,a successful businessman who provided him with US$ 70,000 to found the hospital. Construction on the hospital began in 1922, which became the biggest building in Ethiopia at the time.
In 1928, having initially launched the Abyssinian Frontiers Mission in 1927, then merged it with SIM (at that time "Sudan Interior Mission") in Ethiopia, Dr. Lambie negotiated permission to begin mission work south of Addis Ababa, as far as Sidamo. This was a delicate procedure because Ras Tafari was subject to strong pressures from some in the Ethiopian Orthodox Church.
