The auditorium was designed by renowned Bay Area architects John Galen Howard, Frederick Herman Meyer and John W. Reid, Jr. and built in 1915 as part of the Panama–Pacific International Exposition. The auditorium hosted the 1920 Democratic National Convention, the San Francisco Opera from 1923 to 1932 and again for the 1996 season, the National AAU boxing trials in 1948, and it was the home of the San Francisco Warriors of the National Basketball Association from 1964 to 1967. An underground expansion, named Brooks Hall, was completed in 1958 under the Civic Center Plaza, immediately north of the Civic Auditorium. The famous Mother of All Demos was presented here during the 1968 Fall Joint Computer Conference, and the World Cyber Games 2004 were also held here. In 1992, the San Francisco Board of Supervisors voted to rename the auditorium after the rock concert impresario Bill Graham, who had died the previous year in a helicopter crash. Long before Bill Graham came along, James T. Graham managed the Civic Auditorium from 1954 to 1970 and booked some of the biggest names in show business there. During Jim's tenure, the Civic Auditorium hosted Elvis Presley, Judy Garland, Ray Charles, the Tijuana Brass, Donovan, the Jefferson Airplane, the Mamas and Papas, The Temptations and Gladys Night & the Pips, Jose Feliciano, Bobby Darin and more, which prompted San Francisco Chronicle columnist Herb Caen to opine that they named the Civic Auditorium after the wrong Graham. Jim Graham signed the Warriors to a contract at the Civic in 1962 when they first moved from Philadelphia to San Francisco. The Warriors would play their first few seasons at the Civic before they moved to the Cow Palace, a larger venue. Jim was manager there when Brooks Halls was built as a convention center underground in the Civic Center, adjacent to the Auditorium. Dedicated on April 11, 1958, Jim Graham also managed Brooks Hall, where he booked American Medical Association conventions, the Harvest Festival, the San Francisco Gift Show and more. Under Jim Graham's management, the Civic Auditorium also hosted Barnum & Bailey circuses, the San Francisco Roller Derby, Golden Gloves Boxing matches, professional wrestling, Holiday on Ice, the Ice Capades, car shows, the International Dog Show, the Black and White Ball and the Folderol. In addition, Jim Graham was manager of the Auditorium when President Dwight D. Eisenhower gave a speech there on Aug. 23, 1956, on the 100th anniversary of the founding of the Republican Party, and when a fundraising gala was held there on June 1, 1968 for Democratic presidential hopeful Senator Robert Kennedy, a few days before he was assassinated in Los Angeles on June 5, 1968. At the time, the "Civic Auditorium" was ground zero in San Francisco for conventions and entertainment events. There was no other major venue for large gatherings, outside of the Cow Palace, which was considered ill-equipped for such events despite the fact that it was larger. Later, the Civic Auditorium arena would continue to host concerts by many other famous artists, spanning many different genres. It is owned by the City of San Francisco and since 2010 has been operated by Another Planet Entertainment.
