Cyber Heroes of the Past


This started as a series of articles for ThemNews, the bimonthly journal of Thematics Southern Africa, covering (in most cases) one Cyber Hero at a time who has contributed to the development of the computer. The first monograph appeared in June 2005. Some of the articles have been published in international philatelic magazines, like Thema and Topical Time.
