The helium liquifier, designed by the Cryogenic Engineering Laboratory of NBS, was one-tenth the size of that proposed for the Navy Bureau of Aeronautics. D. B Mann (left), liquid helium project leader, designed the liquification process equipment. B. W. Birmingham (right), Assistant Chief of the Cryogenic Engineering Laboratory, carried out studies of the feasability of helium liquification and transportation at or near its liquid density.
