David Greatrix is an air force brat and Prairie boy who did most of his early growing up in Canada’s capital (Ottawa) and in Germany (Lahr), in addition to spending a good number of his formative years as a child and adult in Winnipeg. As a young adult, Greatrix studied and worked towards making his mark as a professional in the challenging field of aerospace engineering. After a number of years in the aerospace industry, he spent the subsequent twenty-five years of his career as a professor of aerospace engineering at a university located in a major urban center in Canada. Greatrix published a well-received textbook on aerospace propulsion in 2012 (Powered Flight). In 2018, Greatrix published his second book, Farewell to the Good Old Days, a cautionary tale that arose out of his own experiences in an up-and-down academic career. In 2021, Greatrix published his third book, Why Various Canadian Institutions Royally Suck, which is a political and historical narrative that is to some degree a sequel to Farewell to the Good Old Days.
