Marking the largest charitable gift in its 33-year history, the Bolinas Museum has received a $140,000 donation from former board member and art enthusiast Mary “Mimi” Griffin-Jones, who died last year. The funds will go toward the museum’s endowment and will help implement key infrastructure improvements, such as climate control and fire suppression, that will safeguard the museum’s 3,000 objects and art pieces. “For a small institution like us, it makes a big difference,” said Jennifer Gately, the executive director of the museum, which began in an old Quonset hut and which is now a cluster of downtown buildings that house the town’s most prized historical documents, archives and fine art. It has long been in need of a modernizing makeover, Ms. Gately said. The donation arrived amid efforts to catalogue the entire collection database, a years-long process aimed at digitalizing pieces and documents for the benefit of online public viewing and research. “It seems to be a moment right now for the museum,” Ms. Gately said. “Perhaps we can capitalize on that and see some real progress toward beginning to create a proper home for our art.” Ms. Griffin-Jones served on the board from 1994 to 2000, supporteing the museum for over 20 years while spending weekends in her family’s cottage on Wharf Road. One of the Stanford School of Medicine’s first female graduates and a career pediatrician, she took life-drawing classes in Bolinas, where she cultivated a deep love for nature. The museum will honor her life and legacy at this year’s annual Third of July Benefit Cocktail Party.
