John E. Irving
John Ernest Irving CM (January 1, 1932 – July 21, 2010) was a Canadian businessman, the youngest son of the industrialist K. C. Irving of the Irving family. Born in New Brunswick, Jack Irving, as he was called, along with his brothers J.K. and Arthur and their three families, share the ownership and operating responsibility for what is known informally as the Irving Group of Companies. Following their father's death in 1992, ownership and responsibility for the Irving companies was divided as follows:

 James K. Irving (J.K.) – Ownership of and responsibility for Brunswick News and J.D. Irving, Limited a conglomerate which has interests in several industries including forestry, pulp and paper, tissue, Super-calendered paper, building supplies, frozen food, transportation, shipping lines, and shipbuilding. Arthur Irving – Ownership of and responsibility for Irving Oil, its retail stores, oil refineries, oil tankers and distribution terminals and other facilities. John E. Irving (Jack) – Ownership of and responsibility for construction, engineering, and concrete and  steel fabrication companies as well as Commercial Properties, Source Atlantic and Acadia Broadcasting, Limited. All companies within the Irving conglomerate, including Irving Oil and J.D. Irving, Limited are vertically integrated and buy services and products from other companies within the conglomerate, thereby maintaining profits within their operations. Jack Irving gained a reputation as being the most reflective of the Irving family, and was known for being far less aggressive than his older brothers when it came to business, choosing instead to listen intently and leave the talking mostly to them. Many credit this to a kidnapping incident in 1982. Though he was found unharmed, the kidnapping left him aware of his own mortality and a shift in his personality was noted. An avid conservationist of ecological and cultural areas, Jack Irving was a strong supporter of the arts in Atlantic Canada. Irving died at the age of 78 on July 21, 2010, following a brief illness. His survivors include his wife, Suzanne Cameron; two sons, John K. F. and Colin D. Irving (deceased 2019); and a daughter, Anne Cameron I. Oxley. John K. F. Irving succeeded him in his business interests. See also
