Albert Roach Hibbs (October 19, 1924 – February 24, 2003) was an American mathematician and physicist affiliated with the Jet Propulsion Laboratory (JPL).

[3][4] While working as a staff member at JPL, in 1955 Hibbs received a PhD in physics from Caltech with a thesis on "The Growth of Water Waves Due to the Action of the Wind".

He became head of JPL's Research and Analysis Section, and in this role, he was the systems designer for America's first successful satellite, Explorer 1, in 1958.

[9][11][8] As a prominent member of the Southern California Skeptics, Hibbs was awarded a Fellowship from the Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP).

In 1947, Hibbs and Roy Walford took time off from graduate and medical school, respectively, to go to Reno and Las Vegas to beat the casinos at roulette.

[4] Hibbs enjoyed making kinetic sculpture as a hobby[8] and was fascinated by miniaturised, independently operating machines—a field where he once again collaborated in a well known idea-experiment of Feynman's.

Hibbs suggested that certain repair machines might one day be reduced in size to the point that it would, in theory, be possible to (as Feynman put it) "swallow the doctor".

He died in February 2003 from complications following heart surgery at Huntington Memorial Hospital in Pasadena, California.
