Glenn Keith Landguth

Glenn Keith Landguth, P.E.—a humble and devoted family man, accomplished engineer, and lifelong servant to his community—passed away peacefully on June 4, 2026, in Kirkland, Washington. He was 84 years old.

Born on June 27, 1941, in Seattle, Washington, Glenn grew up in a home grounded in love, hard work, and service—values instilled by his parents, Keith Charles and Emma Eleanor Landguth. These early lessons shaped a life defined by integrity, curiosity, and generosity.

A 1959 graduate of Lake Washington High School, Glenn went on to earn a Bachelor of Science in Aeronautics and Astronautics from the University of Washington in 1963, where he also participated in ROTC. Shortly thereafter, he was commissioned as an officer in the United States Air Force, serving honorably from 1963 to 1968 and achieving the rank of Captain. His military service instilled a discipline and steadiness that remained with him throughout his life.

On January 11, 1964, Glenn married the love of his life, Judy Ann McDaniels, at Rose Hill Presbyterian Church in Kirkland. Their 57-year marriage was a partnership marked by devotion, humor, and unwavering support. Judy’s passing in 2021 was a profound loss that Glenn carried with deep tenderness.

Following his military service, Glenn began a distinguished 35-year career as a Stress Analysis Engineer at The Boeing Company. From 1968 until his retirement in 2003, he contributed to major aerospace programs including the early AWACS program, the Minuteman ICBM missile program, and the iconic 747 Commercial Airliner program. His leadership and innovation earned him numerous honors, including Engineering Technology Employee of the Quarter (1987), Industry Engineer of the Year (1998), and multiple awards from the Washington Society of Professional Engineers. He achieved his Professional Engineer designation in 1980 and spent decades giving back to his profession through volunteer leadership, mentorship, and advocacy.

Glenn’s life was rich with interests that reflected his curiosity and craftsmanship. He enjoyed hydroplane racing, model building, gardening, photography, vintage cars, music, and repairing anything that needed fixing. He delighted in understanding how things worked—and in teaching others the same. His Christian faith was central, and he served faithfully in roles such as Deacon, Sunday School Teacher, and Youth Ministry Supporter. He also gave generously of his time to organizations including Young Life, MATHCOUNTS, and the Vintage Chevrolet Club of America, where he enjoyed writing articles and editing newsletters.

Above all, Glenn cherished his family. He is survived by his sister, Nancy Eleanor Bock; his children, Cindy Ann Dusin and Clark Randon Landguth; their spouses, James Robert Dusin and Barbara Suzanne Landguth; and a large, loving family of three grandsons, three granddaughters, and five great-grandchildren—with another on the way—who adored their Grandpa (Papa) and Great-Grandpa. His legacy lives on in their lives, their stories, and the values he modeled so consistently: Christian faith, integrity, curiosity, and kindness.

Glenn will be remembered as a man who loved deeply, served faithfully, and lived with purpose. His presence was steady, his humor gentle, and his generosity abundant. Though he will be profoundly missed, his impact endures in the family he nurtured, the community he strengthened, and the countless lives he touched.

A memorial service will be held at Maltby Community Church, 21111 86th Ave SE, Snohomish, WA 98296, on Saturday, July 11, 2026, at 2:00 in the afternoon. All are welcome to attend.
