Historian Dick van Lente managed to track down a nifty paean to the pioneers of nuclear power, a tribute too many for my book. (I found I could get hold of some issues of Life Magazine but not all.) He writes (p. 64):
Life on August 8, 1955, reflected on the hope of the atomic age as it had been imagined immediately after Trinity. Tellingly, the magazine chose Trinity as its touchstone, not Hiroshima or Nagasaki. Life featured a photo of several men (“rapt young nuclear engineers”) who are the “future executives of a new industrial age – an age powered by the inexhaustible resources of atomic energy.”
