Leonard Andrews died at home on March 24, 2026, surrounded by his family after a lengthy illness. Leonard was born on August 23, 1944, in Baltimore, Maryland, to Mary and Chester Andrews. He was also raised by his Aunt Helen Kufel and his grandmother, Jadwiga, who would have a cold Coke and pierogi waiting for him after school. He attended Calvert Hall College High School and Loyola College of Maryland and was very proud of his Jesuit education. He met his beloved wife, Judy (Mayhew) Andrews, at Case Western Reserve University, where they both earned Ph.Ds. in chemistry. In 2024, Len received an Outstanding Alumni Award from Case Western. In his 40s, Len also earned a master’s degree in computer science from the Harvard Extension School. Len and Judy wed in 1970 and moved to Tucson, Arizona, where Len completed a postdoctoral fellowship in the Department of Chemistry at the University of Arizona. They took full advantage of all Tucson had to offer, regularly hiking the mountains outside the city and collecting cacti. In 1973, Len and Judy moved to the Boston area, where Len spent 37 years working at GTE Laboratories, later Verizon. They raised their two daughters in Wayland, Massachusetts, before relocating to Seattle, Washington in 2013. Len had many interests, including astronomy, travel—particularly to France, wine, his beloved Baltimore Orioles and the New England Patriots, and golf. Above all, his true passions were his family and service to others. He stayed in close contact with the family he grew up with in Baltimore, as well as his nieces and nephews and their children. He loved connecting with the young people in his life and regularly asked about their studies, interests, and future plans. Len dedicated countless hours to his church and community. In Massachusetts, he served as board president of A Place to Turn in Natick, a local food bank, and as president of the United Way of Tri-County. He was also active in leadership at St. Zepherin’s Parish in Wayland and regularly attended Hartford Street Presbyterian Church with Judy. In Seattle, Len was active in the Puget Sound Chapter of the American Chemical Society, serving on its diversity committee, and he was president of the St. Benedict Parish conference of the St. Vincent de Paul Society. He also held leadership roles at St. Benedict Parish in Wallingford and regularly attended Woodland Park Presbyterian Church, where he was the resident technological wizard. Len was a dedicated and loving father to his two daughters, Becky (Scott) Andrews and Emily (Jim) Andrews, and a doting grandfather to Magdalena, Colin, and Elliot. He was preceded in death by his parents and his brother, Melvyn. Len is survived by his wife, daughters, and grandchildren. A Memorial Mass for Len will be held on May 16, 2026 at 11:00 a.m. at St. Benedict Catholic Church, Seattle, Washington. A reception will immediately follow at Ivar's Salmon House, 401 NE Northlake Way, Seattle, WA 98105. In lieu of flowers, the family asks that donations be made to St. Vincent de Paul of Seattle King County (https://svdpseattle.org/) or A Place to Turn (https://www.aplacetoturn-natick.org).
