Stewart Udall, 90, conservationist and cabinet member

Stewart L. Udall, an ardent conservationist and a son of the West, who as interior secretary in the 1960s presided over vast increases in national park holdings and the public domain, died Saturday at his home in Santa Fe, N.M. The last surviving member of the original Kennedy cabinet, he was 90. Mr. Udall had been in failing health after a fall last week, according to a son, Senator Tom Udall of New Mexico. Though he was a liberal Democrat from the increasingly conservative and Republican West, Stewart Udall said in a 2003 public television interview that he found in Washington "a big tent on the environment." The result was the addition of vast tracts to the nation's land holdings and–through his strong ties with lawmakers, conservationists, writers and others–work that led to landmark statutes on air, water and land conservation.
