Progress in low‐temperature physics is so rapid today that it is difficult to realize that the field scarcely existed 100 years ago. Leo Isadore Dana is not a familiar name to many physicists, but his contributions during the years 1920–64, a period of many important advances in cryogenics, span a remarkable range of phenomena in low‐temperature physics and technology. This article recalls some of the important projects, from basic research on liquid helium to a wide range of activities in cryogenic and other technology.
