2004: Ronald Reagan, the 40th president of the United States from 1981–89, dies at the age of 93 in Bel Air, Calif., of pneumonia, brought on by Alzheimer's disease. Reagan, who rose to fame as a radio, television and film actor before entering politics, also served as the governor of California between 1967 and 1975. Some of his most notable films include 1940's "Knute Rockne, All American," 1942's "Kings Row" and 1951's "Bedtime for Bonzo." As a president, Reagan became known for sweeping new political and economic initiatives, such as reducing tax rates to spur economic growth, deregulating the economy and reducing government spending. His time in office also saw the end of the Cold War, the beginning of the War on Drugs, and the revelation of the Iran-Contra affair.
