Oran Kenneth Gragson (February 14, 1911 – October 7, 2002) was an American businessman and politician. He was the longest-serving mayor of Las Vegas, Nevada, from 1959 to 1975. Gragson, a member of the Republican Party, was a small business owner who was elected Mayor on a reform platform against police corruption and for equal opportunity for people of all socio-economic and racial categories. Gragson died in a Las Vegas hospice on October 7, 2002, at the age of 91. The Oran K. Gragson Elementary School located at 555 N. Honolulu Street, Las Vegas, NV 89110 was named in his honor. Howard Walter Cannon (January 26, 1912 – March 5, 2002) was an American politician. He served as a United States Senator from Nevada from 1959 until 1983 as a member of the Democratic Party. In 1956, Cannon ran for the United States House of Representatives to succeed Republican incumbent Clarence Clifton Young, who ran for the U.S. Senate, but lost the Democratic primary to former Congressman Walter Baring, who then won the general election. In 1958, he was elected to the United States Senate, unseating Republican Senator George W. Malone with 58% of the vote.. Cannon was nearly defeated in his first re-election bid in 1964, holding off Republican Lieutenant Governor Paul Laxalt in one of the closest Senate elections ever.
