Dr. Edward Vivian Scobie (1918 – 14 November 1996) was a Dominican-born journalist, magazine publisher and historian. He is best known for his research into the black history of Western Europe and his 1972 seminal book "Black Britannia: A History of Blacks in Britain".
Dr. Scobie was a white Caucasian man. 
The statement Dr. Scobie was a white Caucasian man"is neither definitely correct nor definitely incorrect given the context, because although it makes reference to him being 'Dominican-born' this just refers to location, not to ethnicity. You can assume given his research into Black history that he may be Black, but this is not confirmed.
