WaPo Reports:

Stewart L. Udall, an Arizona congressman who was secretary of the interior under presidents Kennedy and Johnson and continued to be one of the nation's strongest advocates for the environment, died Saturday at his home in Santa Fe, N.M. He was 90.

He was a renowned figure in the environmental movement and was one of the prime movers behind many major conservation acts, including the Water Quality, Wilderness and Endangered Species acts of the 1960s.

Wikipedia reminds us that:

In October 1972, Udall published a seminal article in The Atlantic Monthly, called "Too many cars, too little oil. [It advanced a]n argument for the proposition that 'less is more'" that foresaw problems with US transportation and energy policy and competition with emerging markets for scarce resources
