Samuel Cornette Collins (September 28, 1898 in Kentucky – June 19, 1984 in Washington, DC.[1]) was an American physicist. He developed the first mass-produced helium liquefier, the Collins Helium Cryostat.

Powered by a two-piston expansion engine, his refrigerators provided the first reliable supplies of liquid helium in quantities of several hundred to several thousand liters. Among other uses, these refrigerators were used to liquefy and transport helium and deuterium for the first hydrogen bomb explosion, Ivy Mike in 1952.[2]

He was awarded the John Price Wetherill Medal in 1951 and the Rumford Prize in 1965.
