Under the stimulus of hydrogen bomb development, liquid hydrogen technology advanced rapidly in the first part of the 1950s. A historical review of the scientists and their efforts in advancing this technology from thermonuclear research is presented. The development of the National Cryogenic Engineering Laboratory and mobile liquid hydrogen equipment during this period is discussed. Cryogenic information exchange conferences sponsored by the National Cryogenic Engineering Laboratory are also...
