would assume the office of president. Tyler obliged and was sworn into office on April 6, 1841. Congress convened, and on May 31, 1841, after a short period of debate in both houses, passed a joint resolution, which confirmed Tyler as president for the remainder of Harrison’s term. The precedent that Congress set in 1841 was followed on seven occasions when an incumbent president died, and it was written into the Constitution in 1967 through Section One of the Twenty-fifth Amendment. Legacy Historical reputation Among Harrison's most enduring legacies is the series of treaties that he negotiated and signed with Indian leaders during his tenure as the Indiana territorial governor. As part of the treaty negotiations, the tribes ceded large tracts of land in the west which provided additional acreage for purchase and settlement by the nation. Harrison's long-term impact on American politics includes his campaigning methods, which laid the foundation for modern presidential campaign tactics. Harrison died nearly penniless, and Congress voted his wife Anna a presidential widow's pension of $25,000, one year of Harrison's salary (equivalent to about $ in ). She also received the right to mail letters free of charge. Freehling refers to Harrison as "the most dominant figure in the evolution of the Northwest territories into the Upper Midwest today". Harrison, age 68 at the time of his inauguration, was the oldest person to assume the U.S. presidency, a distinction he held until 1981, when Ronald Reagan was inaugurated at age 69. Harrison's son John Scott Harrison represented Ohio in the House of Representatives between 1853 and 1857. Harrison's grandson Benjamin Harrison of Indiana served as the 23rd president from 1889 to 1893, making William and Benjamin Harrison the only grandparent-grandchild pair of presidents. Honors and tributes Several monuments and memorial statues have been erected in tribute to Harrison. There are public statues of him in downtown Indianapolis, Cincinnati's Piatt Park, the Tippecanoe County Courthouse, Harrison County, Indiana, and Owen County, Indiana. Numerous counties and towns also bear his name. The Village of North Bend, Ohio, honors Harrison every year with a parade to celebrate his birthday. The Gen. William Henry Harrison Headquarters in Franklinton, Ohio, commemorates Harrison. The house was his military headquarters from 1813 to 1814. On February 19, 2009, the U.S. Mint released the ninth coin in the Presidential $1 Coin Program, bearing Harrison's likeness. Notes See also Curse of Tippecanoe List
