Irene L. Brown PhD passed away November 14, 2019, she was 87. Irene was born in St. Joseph, Missouri in 1932 and moved to Los Gatos, California when she was 16. She graduated from Los Gatos High School and subsequently received her BS and MS in Biology from San Jose State University where she met Robert Brown who she married in 1955. She received her PhD in Biology from Stanford in 1971. Irene touched the lives of many in the community and inspired generations of colleagues and students with her scientific knowledge, scrupulous writing and editing, quick wit, warm heart and joy in spending time outdoors. Everyone who knew Irene can recount organisms she identified for us, mysteries she explained, homegrown apples and figs she shared, or life lessons she imparted; most of us can recount all four. She did all of those things with a chuckle and a twinkle in her eyes. We knew she was sharing the things she loved, and we were inspired to love them, too. Irene was a profoundly rigorous scientist.
