Samuel Collins (physicist)

Samuel Cornette Collins (September 28, 1898 – June 19, 1984) was an American chemist, physicist, and engineer.

He taught at Carson-Newman College, the University of Tennessee, Tennessee State Teachers College, and the University of North Carolina, and joined the Massachusetts Institute of Technology as a research associate in the chemistry department in 1930.

After World War II, he returned to MIT, joining the department of mechanical engineering.

"[5] Collin's refrigerators, powered by a two-piston expansion engine, provided the first reliable supplies of liquid helium in quantities of several hundred to several thousand liters.

[6][7] Among other uses, these refrigerators were used to liquefy and transport helium and deuterium for the first hydrogen bomb explosion, Ivy Mike in 1952.
