Lawrence Hill is the son of a white mother from Chicago (‘a kickass civil rights activist’) and a black father (‘most recently from Washington DC … urban, educated, lower middle class’), but grew up in Toronto. Blood: The Stuff of Life, the ninth of his books, originated as the Canadian Broadcasting Commission’s Massey Lectures, an annual series of broadcasts inaugurated in 1961 as a forum where major contemporary thinkers could address important issues of our time. The Australian equivalent is the ABC’s Boyer Lectures.
