9.William Henry Harrison

William Henry Harrison (February 9, 1773 – April 4, 1841) was the ninth President of the United States (1841), an American military officer and politician, and the first president to die in office. The oldest president elected until Ronald Reagan in 1980, and last President to be born before the United States Declaration of Independence, Harrison died on his 32nd day in office[1] of complications from pneumonia, serving the shortest tenure in United States presidential history. His death sparked a brief constitutional crisis, but that crisis ultimately resolved many questions about presidential succession left unanswered by the Constitution until passage of the 25th Amendment.
Before election as president, Harrison served as the first territorial congressional delegate from the Northwest Territory, governor of the Indiana Territory and later as a U.S. representative and senator from Ohio. He originally gained national fame for leading U.S. forces against American Indians at the Battle of Tippecanoe in 1811, where he earned the nickname "Tippecanoe" (or "Old Tippecanoe"). As a general in the subsequent War of 1812, his most notable contribution was a victory at the Battle of the Thames in 1813, which brought an end to hostilities in his region.
After the war, Harrison moved to Ohio, where he was elected to the United States Congress, and in 1824 he became a member of the Senate. There he served a truncated term before being appointed as Minister Plenipotentiary to Colombia in May 1828. In Colombia, he spoke with Simon Bolívar about the finer points of democracy before returning to his farm in Ohio, where he lived in relative retirement until he was nominated for the presidency in 1836. Defeated, he retired again to his farm before being elected president in 1840.

40.Ronald Reagan

Ronald Wilson Reagan (/ˈreɪɡən/; February 6, 1911 – June 5, 2004) was the 40th President of the United States (1981–1989), the 33rd Governor of California (1967–1975) and, prior to that, a radio, film and television actor.

Reagan was born in Tampico in Whiteside County, Illinois, reared in Dixon in Lee County, Illinois, and educated at Eureka College in Eureka, Illinois, with a Bachelor of Arts degree in economics and sociology. Upon his graduation, Reagan first moved to Iowa to work as a radio broadcaster and then in 1937 to Los Angeles, California. He began a career as an actor, first in films and later television, appearing in over 50 movie productions and earning enough success to become a famous, publicly recognized figure. Some of his most notable roles are in Knute Rockne, All American, Kings Row, and Bedtime for Bonzo. Reagan served as president of the Screen Actors Guild, and later spokesman for General Electric; his start in politics occurred during his work for GE. Originally a member of the Democratic Party, he began to support Republican Party candidates in the early 1950s and eventually switched to theRepublican Party in 1962. After delivering a rousing speech in support of Barry Goldwater's presidential candidacy in 1964, he was persuaded to seek the California governorship, winning two years later and again in 1970. He was defeated in his run for the Republican presidential nomination in 1968 as well as1976, but won both the nomination and election in 1980, defeating incumbent Jimmy Carter.

As president, Reagan implemented sweeping new political and economic initiatives. His supply-side economic policies, dubbed "Reaganomics", advocated reducing tax rates to spur economic growth, controlling the money supply to reduce inflation, deregulation of the economy, and reducing government spending. In his first term he survived an assassination attempt, took a hard line against labor unions, and ordered an invasion of Grenada. He was reelected in a landslide in 1984, proclaiming that it was "Morning in America". His second term was primarily marked by foreign matters, such as the ending of theCold War, the 1986 bombing of Libya, and the revelation of the Iran-Contra affair. Publicly describing the Soviet Union as an "evil empire",^[1] he supported anti-communist movements worldwide and spent his first term forgoing the strategy of détente by ordering a massive military buildup in an arms race with the USSR. Reagan negotiated with General Secretary of the Communist Party of the Soviet Union Mikhail Gorbachev, culminating in the INF Treaty and the decrease of both countries' nuclear arsenals.

Reagan left office in 1989. In 1994, the former president disclosed that he had been diagnosed with Alzheimer's disease earlier in the year; he died ten years later at the age of 93. He ranks highly in public opinion polls of U.S. Presidents and is credited for generating an ideological renaissance on the American political right.
