Richard Nixon's 100th birthday noted with ceremony in California YORBA LINDA, Calif., Jan. 6 (UPI) -- Tricia Nixon Cox will lead a ceremony in California Sunday marking the 100th birthday of her late father, President Richard Nixon, the Nixon Foundation said. Cox and a number of dignitaries gather at Nixon's birthplace in Yorba Linda where the admission charge was being waived to mark the centennial. Cox will formally present a White House memorial wreath, and speakers including former White House assistant Bruce Herschensohn will pay tribute to the 37th president of the United States, the foundation said in a written statement. The event also includes a Marine Corps band and a 21-gun salute. President Nixon was the only U.S. president to resign while in office, but was also remembered for accomplishments including easing Cold War relations with China and the Soviet Union. Nixon died in 1994.
