The United States passed a milestone October 28, 2015. Few people noticed. We now have a new record for US Presidents not dying in office.
George Washington was inaugurated April 30, 1789. All Presidents lived to finish their time in office for 51 years and 339 days. William H. Harrison died April 4, 1841.
Mr. Harrison was the first of the zero factor Presidents. From 1840 until 1960, any man elected President, in a year ending in zero, died in office. In recent times, Ronald W. Reagan and George W. Bush survived the zero factor. Maybe the middle initial made a difference.
John F. Kennedy made an unwise trip to Dallas TX on November 22, 1963. No President has died in office since then. 51 years and 340 days went by on October 28, 2015. Barack H. Obama is assumed to be happy about this.
While no Presidents have died in the last 52 years, there was one that did not finish his term. Richard M. Nixon resigned from office August 9, 1974. He did live another 20 years. Pictures for this feature are from The Library of Congress.
