Rumford's Soup was an early effort in scientific nutrition. It was invented by Benjamin Thompson, Reichsgraf von Rumford, circa 1800 and consumed in Munich and greater Bavaria, where he was employed as an advisor to Charles Theodore, Elector of Bavaria. It was used as a ration for the poor, for Bavarian workhouses and military workhouses, and prisoners. Count Rumford has been credited in many instances for "establishing the first real soup kitchen."

Sir Benjamin Thompson, Count Rumford, FRS was a British physicist, born in Colonial Massachusetts, and inventor whose challenges to established physical theory were part of the 19th-century revolution in thermodynamics. He served as lieutenant-colonel of the King's American Dragoons, part of the British Loyalist forces, during the American Revolutionary War. After the end of the war he moved to London, where his administrative talents were recognized when he was appointed a full colonel, and in 1784 he received a knighthood from King George III. A prolific designer, Thompson also drew designs for warships. He later moved to Bavaria and entered government service there, being appointed Bavarian Army Minister and re-organizing the army, and, in 1792, was made a Count of the Holy Roman Empire.
