Erwin Angus began his public service with the Government of Ontario, but returned to Jamaica to join the foreign service as the Jamaican representative to Latin America and the United States. He then transferred to the Ministry of Mining and Natural Resources, serving as secretary to the National Bauxite Commission and writing the original paper which helped establish the Jamaica Bauxite Institute. He also helped form the State Petroleum Corporation to secure the nation’s energy resources in the height of the 1970s oil crisis.
Angus later became the chair of the Maritime Institute of Jamaica, successful extending it across the entire Caribbean. The institute is now known as the Caribbean Maritime University. After leaving public service in 1986, Angus became the managing director of Mayberry Investments Limited -- a position he still holds today. He was granted Jamaica’s Order of Distinction (commander class) in 1976 and became a Justice of the Peace in 1977.
