“On Nuclear Energy: Its Potential for Peacetime Uses” by Donald J. Hughes, published in 1957 by Harvard University Press, is a significant book that explores the potential applications of nuclear energy for peaceful purposes in the mid-20th century. At a time when the world was still grappling with the implications of the atomic bomb, Hughes, a prominent nuclear physicist and one of the signers of the Franck Report (which advocated against the military use of the atomic bomb), sought to shift the focus towards the constructive uses of this new technology.
