Background
Roskill was born on November 10, 1933 in London, United Kingdom; the son of Stephen W. and Elizabeth C. H. (Van den Bergh) Roskill.
Mark's passion for art history might have been preordained. His father was the official naval historian, and his mother - one of the first women to be trained at the Slade, painted and collected painting throughout her life.
Roskill came to the United States in 1959.
