Scottish cartographer and explorer. One of the most accomplished geographers ever sent to explore Africa, Alexander Keith Johnston the Younger was born at Edinburgh, on November 23, 1844, the son of a distinguished father who ran an Edinburgh business specializing in the publication of atlases and reference works. The young Johnston worked for his father, then briefly for the rival firm of Stanford, studied German cartographical methods with Augustus Petermann, and then became a map curator at the Royal Geographical Society (RGS). His considerable geographical and cartographical writings included a study of the Nile problem when it was still uncertain where the river's sources lay. Johnston garnered practical experience as a surveyor for the Paraguayan government on the border with Brazil in 1873.
