Ray Gilbert Kummerow, 89, of Bainbridge Island passed away Friday, January 18th, 2019 at Harrison Medical Center, Bremerton, Washington. Born in Chicago, Illinois he was the son of the late Harold and Ruth Kummerow. As a teenager, Ray worked for the Idaho Forestry Department, where he became interested in the US Naval Academy (USNA) from working alongside WW2 vets. Ray studied Mathematics, engineering, and Russian linguistics at the USNA and chose a commission into the US Marine Corps upon graduation in 1952. Ray served in Korea for one year joining the 3rd Battalion, 9th Marines, 3rd Marine Division, and became the Platoon Commander of a Weapons Company there. His service following Korea included teaching nuclear, biological, and chemical warfare to incoming officers at Quantico. Ray developed a physical training program that included hand-to-hand combat, bayonet fighting, obstacle courses, and testing. He then taught Mathematics at the USNA. During the Vietnam War, Lieutenant Colonel Ray Kummerow assumed command of the 3rd Battalion, 7th Marines in August 1969. Ray was wounded during the Summer Offensive in the Heip Duc Valley region of the Que Son Mountains. Ray cites General Lewis Walt, former assistant commandant of the Marine Corps, as his inspiration. “’I did my best’ is what he said when describing his service. It was always about the marvelous people I served with or commanded. The Marine Corps, its heritage and its achievements, are nothing but the people.” Ray married his first wife, Patricia Bergin, and had three children: Sean, Sheila, and Tim. Ray met his second wife, Phyllis, onboard a US Naval ship crossing the Pacific Ocean. They had three sons: Phillip, Eric, and Grant. Ray and Phyllis were married for 50 years at the time of her passing in 2018. Ray retired from the Marine Corps in 1975 as a Colonel, and in 1979 the family moved to Bainbridge Island, Washington. Ray taught Mathematics at several universities in the Puget Sound area, and then worked for the Boeing Company for 20 years. He held multiple project positions in project/program management and systems engineering roles in Aerospace, Commercial Airplanes, and Boeing Computer Services, becoming a mentor for many at Boeing. Ray’s passion for teaching and mentoring extended long after retirement. Always with great energy, focus, and enthusiasm he guided and inspired others as they pursued leadership careers as entrepreneurs, academic thought leaders, and industry specialists. Semper Fi Ray is survived by his five sons Sean, Tim (and wife Ping) Bergin, Phillip (and wife Deborah), Eric, Grant (and wife Diane). His daughter Sheila (and husband Jack) Garbade, along with his beloved grandchildren; Blair (and husband Matt) Martlaro, Lindsay, Aidan, James, and Claire.
