On July 19, 1990, the Richard Nixon Library and Birthplace in Yorba Linda, California opened as a private institution with the Nixons in attendance. They were joined by a large crowd of people, including Presidents Ford, Reagan, and George H. W. Bush, as well as their wives, Betty, Nancy, and Barbara.[262] In January 1994, the former president founded the Nixon Center (today the Center for the National Interest), a Washington policy think tank and conference center.[263][264]
