Heinrich G. Schlichter (or Henry Schlichter, as author of publications in English) obtained the Doctor of Science (DSc) degree and became a writer on the geography and prehistory of Africa. One of his papers, "The geography of South West Africa; with a bibliography of South West Africa from 1884 to 1891", was read at the 1891 meeting of the British Association for the Advancement of Science and published in the Scottish Geographical Magazine that same year. It consisted of a comprehensive general overview, based largely on earlier publications, describing expeditions to the region between the Orange River and the Kunene and Okavango Rivers, including its flora, fauna and native inhabitants. That part of the paper dealing with the meteorology of the region was published separately in the Quarterly Journal of the Royal Meteorological Society (1891).
A number of other papers by Schlichter dealt with the prehistory of present Zimbabwe. In "The ruins of Mashonaland" (Geographical Journal, 1893) he reviewed J.T. Bent's* book, Ruined cities of Mashonaland. That same year he published "Historical evidence as to the Zimbabwe ruins" (ibid, 1893), in which he expressed the belief that the ruins were of pre-Christian Arab origin. Six years later, in his "Travels and researches in Rhodesia" (ibid, 1899) he described his explorations in Mashonaland and Matabeleland during 1897.
Schlichter edited and translated Problems of nature, researches and discoveries of Gustav Jaeger, MD (London, 1897). Other publications by him included papers on "Ptolemy's topography of eastern equatorial Africa" (1891), "The pygmy tribes of Africa" (1892), "The determination of geographical longitude by photography" (1893), and "Ueber den Namen Simbabye und seine Bedeutung" (On the name Simbabye and its meaning, 1893).
