Thomas Chalmers Robertson

Dr. Thomas Chalmers Robertson was a writer, 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 of Southern Africa, his insatiable quest for knowledge, and his equally insatiable hedonism.
The T.C.Robertson Nature Reserve situated on the outskirts of the town of Scottburgh, KwaZulu-Natal is named after him, and he played a role in the development of Ilanda Wilds.
According to Dictionary.com, Robertson coined the term "white nationalism" in his 1948 essay titled Racism Comes to Power in South Africa: The Threat of White Nationalism. However, Merriam-Webster has noted usage of the two-word phrase as early as 1925.
