The Baker Street Foundation is a foundation founded and operated by the family of Robert M. Miner, the late co-founder of the software multinational Oracle Corporation, and his widow, Oakville Ranch Winery owner Mary Miner. 
It has no public mission statement nor website. It makes a number of grants to San Francisco-based parks, arts, education, medicine and social relief organizations.  The foundation provides funding to several left-of-center organizations including Planned Parenthood, Earthjustice, Safe and Sound, and National Organization for Women. 
The Baker Street Foundation was granted non-profit status in April 1995, shortly after the death of Robert M. Miner, co-founder of Oracle, from cancer.  The Miner family was ranked number 170 on the Forbes “Richest American Families” list in 2014 with an estimated wealth of $1.1 billion, but fell from the list in later years. 
The foundation holds assets with a fair market value of $90,832,386 at the end of 2017.  The entirety of the foundation’s funding comes from the Miner family and returns on investment assets contributed by the Miners.
Grants to Earthjustice, Safe and Sound, National Organization for Women (NOW), University of San Francisco School of Law – Immigration Clinic, and Planned Parenthood are indicative of the foundation’s left-of-center tilt. Nicola Miner, a director for Baker Street Foundation and daughter of Robert and Mary Miner, and her husband, Robert Mailer Anderson, hosted a $35,800 per-plate fund raising dinner for President Barack Obama and support the Natural Resources Defense Council and Planned Parenthood. 
Mary Miner is the widow of Robert Miner, a co-founder of Oracle. In addition to her role of co-founder of the Baker Street Foundation, she owns the Oakville Vineyards in Napa County and is a director of Mmm Management, a financial advisory firm in San Francisco. 
Nicola Miner is the oldest child of Mary and Bob Miner and is married to author Robert Mailer Anderson, a member of the San Francisco Jazz Center.  In addition to her role with the Baker Street Foundation she serves on the Board of Trustees of Earthjustice, and previously as a director of the Presidio Trust, San Francisco University High School, The San Francisco Ballet, and The San Francisco Museum of Modern Art. She is an instructor at the College of San Mateo and President of Miner Anderson Family Foundation. Both are members of the Democratic Party. 
Luke Miner, the son of Robert and Mary Miner, is a data scientist and co-founder of Tunebend, a music application for smartphones. 
Helen Sedwick is an attorney at Bennett Valley Law, a firm that she founded in 2007, representing entrepreneurs and small businesses. She has sat on the board of the Baker Street Foundation since 2002. She has wrote a book titled The Step-by-Step Guide to the Legal issues of Self-Publishing. 
Roy Bukstein, CFO and director of the foundation, is also CFO of Mmm Management and RNM Properties , both of which are Miner family-controlled organizations. He served as CFO and treasurer of Oracle Corporation from 1980 through 1988, during which time he worked with Robert Miner. 
Total income for 2017 was $1,405,436  versus $5,161,232
(includes $487,438 in non-cash contribution from Mary Miner) in 2016.  Expenses for 2017 were $6,919,176 (including $5,977,827 in grants)  versus $5,027,163 (including $4,553,588 in grants) in 2016.
