In her most recent book, History's People: Personalities and the Past, historian Margaret MacMillan takes a provocative look at the people who have helped to shape our world. She delves into their character, the risks they took and sometimes the diaries they kept. It is a book that breathes life into the idea that there is an intimate connection between history and biography. The 2015 Massey Lectures will be broadcast on the CBC Radio One program Ideas, from November 2 - 6.
