Andrew Mark Crabtree MBA ’63 of Issaquah, Wash., passed away in his home at University House on Dec. 12, 2011, with his family present. He was born Feb. 3, 1925. His final years were marked with numerous health problems, but throughout it all he maintained a cheerful and optimistic outlook on life. The love for his family, and by his family, instilled in him a very strong will to live, inspiring him to pursue new treatment options even the day before his death.

Born and raised in Kansas, the only child of Bessie and Arthur Crabtree, Mark was preceded in death by his infant son Mark and by his wife Ann Faup, the love of his life for 65 years. His three surviving children are Michele Cage and Shawn Crabtree, both of Issaquah, and Yolande Wackerman, of Menlo Park, Calif.; his eight grandchildren; and one great-grandchild. His service in the United States Air Force and his civilian work as an industrial engineer brought him much personal satisfaction.
