Dar attended schools in New Canaan CT and graduated from the Hotchkiss school. After graduating,from Yale, Dar went on to earn an MBA from the University of Chicago’s Booth School of Business in 1966 and pursued a career in business and management that included stints at Union Carbide and Hubbell.

He was also president of a furniture company called Formatron. Darwin did important consulting work and was the author of The Noble Enterprise, a book about the surprising turnaround of a major Canadian company that used effective strategies to uplift and inspire its workforce towards shared purpose and values, and thus better productivity and product.

A loving husband of 58 years, Dar and his surviving wife, Barbara (also known as “Ara”), moved from New Canaan to Avon, Connecticut in 1979 and began living in Phippsburg and Bath, Maine in the late 1990s. They loved spending the winter months in Englewood, Florida where they built a strong network of friends together through their involvement with The Venice Unity Church. A lover of the Outdoors, Darwin introduced his children to camping, hiking, and boating. Although hampered with numerous health problems through the last decade and a half of his life, Darwin never lost his positive spirit, and had the ability to earn the affection of every acquaintance he met. He is survived by his wife, Ara; his four children, Darwin (Kristin), Thomas (Tammy), Timothy, and Mary; his four grandchildren Avery, Parker, Kelly and Annika and by his sister Marie.
