Why is "Alexander Murdoch Mackay" trending?

Wikipedia Overview

Alexander Murdoch Mackay was a Scottish Presbyterian missionary to Uganda also known as Mackay of Uganda. After studying math, drafting and other technical subjects at several universities, Mackay, at age twenty-five, decided to dedicate his life to Christian missionary work, and saw this as a great opportunity to put his technical skills to beneficial use. He was assigned to serve in Uganda by the Church Missionary Society in 1876. While serving as a missionary he performed religious and educational services for the native people of that country; however, his mission was often at risk due to the almost constant tribal wars that surrounded the mission, often instigated by Arab traders and Muslim tribes. During the Emin Pasha Relief Expedition Henry Morton Stanley visited Mackay at the Usambiro mission for a short period where he received aid and local information from him. Mackay worked with David Livingstone and Sir John Kirk to help bring an end to the brutal Arab slave trade in central Africa.
