Among the division's various programs, the best known in the scientific world was its program in low-temperature physics. The Bureau had been involved in cryogenic research since 1904 when it obtained a hydrogen liquefier, but it was not until 1948, when it obtained a helium liquefier, that low-temperature physics research began in earnest. Built up by Brickwedde and supported by Condon, the low-temperature physics laboratory became one of the best in the world. It attracted a number of outstanding scientists.
