He was born in Portland, OR on Dec. 26,1937 to Theodore "Ted" Piele and Helen Hanson Piele. Don grew up in Vancouver, WA, graduating from Hudson's Bay High School in 1956.

This annual competition, held in schools from 45 states and 12 countries, ran until 1993. In 1992, he established the USA Computing Olympiad to train and select high school teams to compete in the International Olympiad in Informatics and over the next 17 years led U.S. teams to Olympiads all over the world.
