1943  Lois Weston Weeth, a past president of the Cal Aggie Alumni Association, former UC regent and past chair of the UC Davis Foundation, turns 80 this year, and her family plans to celebrate with an open house, Feb. 2, 1-4 p.m., in the AGR room of the Alumni and Visitors Center at UC Davis. Friends are invited to attend; in lieu of gifts, contributions are suggested for the alumni scholarship program, the UC Davis arboretum or herbarium. Weeth continues to serve the campus, working as a docent at UC Davis' Bodega Marine Laboratory, as she has for the past 12 years, and assisting John Tucker, professor emeritus of plant biology, with an ongoing study of native oaks in Mendocino County.
