Lived in Tucson
Why he's famous: Politics — U.S. House of Representatives
Notable accomplishment: Udall was a member of the U.S. House of Representatives from Arizona. He then became the 37th U.S. secretary of the Interior, under Presidents Kennedy and Johnson. During that time, he added four new parks, six national monuments, eight seashores and lakeshores, nine recreation areas, 20 historic sites and 56 wildlife refuges to the National Park system.
In 1961, Udall persuaded President Kennedy to add 15,000 acres to the west unit of the Saguaro National Monument, today part of the national park that bookends Tucson on the east and the west.
Udall created the first federal bike path and the first jogging trail at a time (1961) when newspaper accounts had to explain the term "jogging."
