Dr Norman Morrison was born in Dewetsdorp in the Orange Free State in 1928, and holds degrees in electrical engineering and applied mathematics. He lived in the United States for 30 years, from 1956 to 1986. He worked in US military defence for thirteen years, including four years at Bell Labs on ballistic missile defence, where he first learned about tracking filters.
After returning to South Africa in 1986, he taught applied mathematics at the University of Cape Town for twenty years until 2007.
From 2008 to 2013, he was employed by Armscor (South African Department of Defence) and assigned to work with Reutech, located in the Stellenbosch Industrial Park. The project involved the development of a new type of TWS radar that was to operate in conjunction with surface-to-air missiles provided by Denel Aerospace, located in Centurion, Pretoria.
Out of this work came a book entitled Tracking Filter Engineering: The Gauss-Newton and Polynomial Filters – that was published by the IET (UK).
