was published in 1967. The book depicts Williamson as quiet to the point of secretive, and something of a womanizer. However, it also hails him as the last of the great diamond prospectors, who were able to find meaningful deposits and establish significant, successful mines without outside resources or support. While the book is known to have taken some liberties with the facts, it is one of the few biographical sources available. John Gunther in Inside Africa gives an account of a visit to the mine, describing Williamson as (partly on account of ill health) "an almost total recluse" whose one hobby was collecting first edition books. In 2011 Williamson was inducted into the Canadian Mining Hall of Fame. References Further reading Tassell, Arthur. African Mining Magazine. "Williamson - A Bright Future Ahead?".
