Zobrist of the Harry S Truman Library, Independence, Missouri;
Richard L. Ray of the National Atomic Museum, Albuquerque;
and Spencer Wilson, Professor of History at the New Mexico
Institute of Technology, who also doubles as the head of the
Socorro Historical Society. I would also like to offer a special
word of appreciation to Dana Asbury of the University of New
Mexico Press and to Dorothy Wonsmos, head of the Interlibrary
Loan Division, Zimmerman Library, University of New Mexico.

Personal interviews provide the most rewarding aspect of re-
search in modern American history. I would like to thank the
following people for taking time to share their recollections with
me: Herbert L. Anderson, Hans A. Bethe, Berlyn Brixner, Ted
Brown, Norris Bradbury, Holm Bursum, Jr., Roy W. Carlson, Sam
P. Davalos, Neil Dilley, Frank DiLuzio, Hymer L. Friedell, Robert
W. Henderson, Louis Hempelmann, Jr., Jack M. Hubbard,
McAllister Hull, Jr., Leo M. Jercinovic, Kermit H. Larson, Dor-
othy McKibbin, John Magee, George Marchi, Lilli Marjon, James
F. Nolan, Frank Oppenheimer, Lois Page, Thomas Treat, Stan-
islaw M. Ulam, Marvin and Ruby Wilkening.

Mel Merritt, Al Solomon, and Charles Wood always had val-
uable advice on whom to interview next. Louis Hempelmann,
Jack M. Hubbard, Kermit Larson, John Magee, Noel Pugach, Jack
Reed, Richard Robbins, Jr., and Donald Skabelund did yeoman
work in giving a critical reading to various sections of the
manuscript.

Kenneth T. Bainbridge critiqued an entire draft and provided
valuable personal insights. I would also like to thank Kermit
Larson for lending me his copies of the UCLA Trinity surveys,
Mrs. Stafford Warren for allowing me to read her husband's rem-
iniscences, Kenneth T. Bainbridge for letting me read his Co-
lumbia oral history, and Barton C. Hacker for lending me the
draft version of his "Elements of Controversy: A History of Ra-
diation Safety in the Nuclear Weapons Testing Program." I would
like to credit L. George Moses and George Lubick of Northern
Arizona University, Flagstaff, and Alfred Castle and William Gibbs
of the New Mexico Military Institute in Roswell for permitting
me to test out some of my early ideas on their unsuspecting
students. Marion Honhart and, especially, Penelope Katson should
be lauded for their efforts in deciphering my handwriting, some
of which, I discovered, I couldn't read myself.
