Douglas Knox Armstrong, fondly known as Knox to friends and family, died on Feb. 18, 2013 peacefully after a short illness, at the age of 89, at Valley Hospital in Ridgewood, N.J.

Born in Rockland, July 25, 1923, Knox grew up in Massachusetts and Maine. He was a graduate of Newton High School and Dartmouth College. During the Second World War Knox served in the Navy as a Lieutenant J.G. in the Pacific Theater. After the war he enjoyed a long career in the publishing field in New York City. He served as publisher for Chemical Week Magazine and Dunn’s Review. During this time Knox and his wife resided and raised their children in Saddle River, N.J.

During his life Knox enjoyed many long hours of bridge with friends. He and his wife were both avid golfers and together played frequently in Rockland. Above all, Knox loved Friendship. His time spent on the water and on the islands of Muscongus Bay were very precious to him.

Knox is survived by his wife Marion of Mahwah, N.J.; daughter Allison of Biddeford; son Scott and his wife Dianne of Newtown, Conn.; three grandsons Christopher, Colin and Patrick, and sister Judith Lambert of Portland.

A celebration of life will be held this summer on a date yet to be determined. Those who wish to make a memorial contribution may do so to the Friendship Library, 3 Main St., Friendship, ME. 04547.
