Roberta Wohlstetter, American political scientist, historian, and academic (b. 1912)
Roberta Mary Morgan, better known by her married name of Roberta Wohlstetter (August 22, 1912 – January 6, 2007), was one of America's most important historians of military intelligence. Her most influential work is Pearl Harbor: Warning and Decision. The former Secretary of Defense, Donald Rumsfeld, is said to have required that his aides read it. Indeed, it was brought up during discussions of intelligence failures leading to the successful al-Qaeda attack on the World Trade Center and Pentagon.She was the daughter of Edmund M. Morgan, Jr., a noted Harvard law professor who helped to simplify the federal rules of civil procedure and to modernize the U.S. code of military justice. Her husband was the late nuclear strategist Albert Wohlstetter.

She was awarded the Presidential Medal of Freedom by President Ronald Reagan jointly with her husband in 1985. Reagan said:

Roberta Wohlstetter, a generation ahead of her time, asserted her influence in areas dominated by and, in some cases, reserved for men. She rose above all obstacles and has had a profound influence. Her inquiries went to the heart of the system of our society, focusing on essential questions. Her analysis of the problems of terrorism, intelligence, and warning and, with Albert [Wohlstetter], the problem of nuclear deterrence broke new ground and opened new alternatives for policymakers. I daresay that she has blankly enjoyed posing the same penetrating questions to her husband that she has to the intellectual and political leaders of the country. And that is certainly one explanation for the clarity and persuasiveness of his own voluminous words on strategy, politics, and world affairs.

Wohlstetter worked for the RAND Corporation, a nonprofit research organization based in Santa Monica, California, from 1948 to 1965 and continued to be a consultant through 2002.

Roberta Morgan Wohlstetter died at 4:00 a.m. on January 6, 2007 at New York Hospital in New York City. She was 94 years old. She was survived by her daughter Joan Wohlstetter-Hall.
