In 1932, Pierre and Gracieuse Elissondo purchased the Glass House and 103 acres from the estate of Loretta Glass, the last Glass family member to live there. Known as Pete and Grace, they raised their two children and many foster children in the home and operated a restaurant there, The Farmhouse Inn, from 1932 to 1938. In 1948 they moved out of the Victorian house but kept it as a rental property. After their parents' deaths, Clement and Elaine became the acting landlords. Over the years, the house was leased to a series of tenants and used as a rest home, a Montessori school, a real estate office, and office space for numerous professionals. The Elissondo family owned and preserved the Glass House for 66 years until the property was sold in 1998 and eventually acquired by the City of San Ramon for use as a museum. Pierre and Gracieuse were immigrants from the Basque region of southwest France. Their son Clement was born in France, and their daughter Elaine, born on October 9, 1933, a year and a half after they moved into the house, was the only child born in the Glass House.
