Raymond Matthew Fuoss (September 28, 1905 – December 1, 1987) was an American chemist who researched mainly on electrolytes, polyelectrolytes, and polymers.

[3] While at Brown, Fuoss was the recipient of the ACS Award in Pure Chemistry.

[4] The award came with a monetary prize of $1000 for his achievement of producing the "first comprehensive theory of electrolytic solutions.

"[1] Due to limited financial resources for university research during the Great Depression in the mid-1930s, Fuoss was contacted by the General Electric Research Laboratory, where he worked until the end of the Second World War.

[2] Fuoss eventually retired from Yale University in 1974 but continued active research in electrolytes.
