Abstract
The author, who edited The Frontier in History: North America and Southern Africa Compared (1981) with the late Leonard Thompson, tells how he first met Thompson and later organized with him a series of graduate student seminars comparing the North American and southern African frontiers. He then discusses the publication of their book, which appeared the same year as George Fredrickson's White Supremacy, and how their work (together with Fredrickson's research) has influenced comparative frontier studies today.
