In Loving Memory: Stan Ecklund


Stanley Duane Ecklund passed away peacefully on April 8, 2025, at the age of 86, surrounded by his family after a short battle with pancreatic cancer. A devoted husband, father, grandfather, scientist, and friend, Stan will be remembered for his steady presence, deep faith, and kind heart.
Born in Minneapolis, MN, to Arnold and Mabel Ecklund, Stan graduated from Roosevelt High School and earned a B.S. from the University of Minnesota. He completed a Ph.D. in high-energy physics at Caltech in 1967. He dedicated his career to particle physics, working at several major laboratories, including Fermilab and the Stanford Linear Accelerator Center (SLAC), where he contributed to groundbreaking research and accelerator design over nearly three decades.
Stan married Marian Holmgren in 1964, and together they raised three sons: Karl, Kreig, and Kier. They lived in Illinois and California, most recently in San Jose. Stan was a longtime member of Foothill Covenant Church, where he sang in the choir, led Bible studies, and served faithfully for 45 years.
He is preceded in death by his wife, Marian; his parents; and sister, Audrey Gustafson. He is survived by his sons and their spouses, six grandchildren, and many nieces, nephews, and dear friends.
