Dr. Thomas Chalmers Robertson (15 September 1907 – 11 January 1989) was an author, ecologist and conservationist from South Africa. He was also a war correspondent, and Jan Smuts’s anti-Nazi propagandist during World War II. He was driven by three things: his mission to save the soil (and grasses of Southern Africa), his insatiable quest for knowledge (being regarded by some as a genius), and his equally insatiable hedonism.
