Colonel Sir John Wallace Pringle (c1863-1938)
1883 Became a lieutenant in the Royal Engineers. As an army officer, Pringle fought in the Third Anglo-Burmese War, 1885–1886.
In the Uganda Railway survey between 1891 and 1892, Pringle was second in command to James Macdonald. The survey's findings confirmed that the caravan route to the Great Rift Valley was the best path for the line, followed by the easiest gradient to be found over the Mau Escarpment and down to Lake Victoria. Macdonald and Pringle recommended construction of a three-foot six inch gauge railway. They suggested that Kikuyuland would be a suitable place for whites to live, and their civilizing effect would drive out slavery, but the railway was needed to give access to the new colony.
Became a Fellow of the Royal Geographical Society and received the Gill Memorial from this society in 1895 for his work on the Uganda railway survey.
In 1896, he was appointed as the superintending engineer on the survey and construction of the Hyderabad-Godavari Valley Railway which comes under the Nizam's Guaranteed State Railway.
