Political scientist Lynton Keith Caldwell, a principal architect of
the National Environmental Policy Act of 1969 (NEPA) who also is
recognized as the “inventor” of the Environmental Impact
Statement (or EIS, NEPA's “action forcing” provision), is
widely regarded to be one of the twentieth century's most influential
scholars in the fields of environmental policy, politics, law, and
administration. Indeed, because of his groundbreaking work during the
1960s, he has been credited with founding the new subfield of
environmental policy, politics, and administration studies within the
wider scope of political science and public administration in the United
States. In that period, Robert Bartlett and James Gladden believe that
Caldwell “proposed the wholly new field of inquiry now known as
environmental policy studies” and that he was “alone in
focusing on the distinctive, integrative character of the concept
‘environment’ and its implications for politics, public
policy, and public administration.” Harold and Margaret
Sprout, the only other political scientists then pursuing a path similar
to Caldwell's, share this opinion, writing in 1978, “The long
neglect of environmental subjects by academic political scientists
[has been] verified … The roster of an interdisciplinary
conference, ‘Man's Role in Changing the Face of the
Earth’ (1955), sponsored by the Wenner-Gren and National Science
Foundations, included no political scientists. Two years later the
conference ‘Future Environments of North America’ sponsored by
the Conservation Foundation included only one, Professor
Caldwell.”
