Presidents of the club in the second half of the 20th century included actress and Ambassador Shirley Temple Black, California Supreme Court Justice Ming Chin, and UCSF Chancellor Julius Krevans. Club members include prominent national leaders like former Secretary of State George Shultz and former Defense Secretary William Perry, as well as citizens from professions such as business, law, medicine, teaching, the arts, technology and journalism. The club has hosted numerous world-class speakers including many U.S. presidents and other major political leaders in the United States and abroad, business leaders, and influential social activists. Speakers receive no honoraria. In 2002, The Commonwealth Club launched Inforum, dedicated to serving the needs of people in their 20s and 30s interested in non-partisan public affairs. In 2007, the Club created Climate One to bring together academics, industry, and activists on all sides of energy and climate change issues for discussion and planning. The club has its headquarters in San Francisco. Though the majority of its programs are in San Francisco, Silicon Valley, Marin County and Lafayette (in the East Bay area northeast of San Francisco), it also hosts occasional events in Sacramento, Southern California and Washington, D.C. A second, small office serving Silicon Valley is in Milpitas, California. In September 2017, the Club celebrated the opening of its first owned headquarters, a 24,000 square ft, $33 million building, on the San Francisco waterfront at 110 The Embarcadero. The building was designed by Leddy Maytum Stacy, a San Francisco architectural firm and winner of the American Institute of Architects 2017 Firm Award. The building is specifically designed to be a civic forum, with auditoriums, the Meyer Sound Constellation system, Copper Loop hearing technology, informal conversation areas, audio-video production facilities, digital information screens and other unique elements to serve the Club's mission. It is also a historic restoration of a building that was the first headquarters of the International Longshoremen's Union. The Club's HQ is environmentally sustainable, with features including cooling with outside air, paneling with wood reclaimed from the original building on the site, LED lighting and tile and carpeting with recycled content. It is also located close to public transit facilities serving the Bay Area. The list of notable speakers and speeches numbers in the thousands and includes domestic and foreign political and military leaders, Nobel prize-winning scientists, authors, activists, and artists. A book of important club speeches, "Each a Mighty Voice", was published in 2004 by Heyday Books.
