2015 is the 50th anniversary of the establishment of the Bay Conservation and Development Commission, which for a half century has successfully protected and preserved San Francisco Bay. The legislation establishing BCDC was accomplished by the grassroots Save the Bay Movement, launched in 1961 by three extraordinary Berkeley women. The Berkeley Public Library commemorates these events with two talks by Berkeley City College historian Chuck Wollenberg, discussing Berkeley’s role in the emergence and accomplishments of the Save the Bay Movement and the city’s larger influence on the Bay Area’s environmental consciousness. The sessions will be in the Berkeley History Room of the main library from 2-3:30, Saturdays June 20 and June 27. Free admission.
