John Standard did not invent the refrigerator. He registered his patent for an improved refrigerator design on June 14, 1891. John Standard was an African American inventor from Newark, N.J., responsible for the patent on an improved refrigerator cooling system. John Standard found a way to improve the existing design of refrigerators by developing a non-electrical and unpowered design.
Credit for the invention of the electric refrigerator should go to Fred Wolf and Nathaniel Wales. In 1913, refrigerators for home and domestic use were invented by Fred W. Wolf of Fort Wayne, Indiana with models consisting of a unit that was mounted on top of an ice box.[6] In 1914, engineer Nathaniel B. Wales of Detroit, Michigan, introduced an idea for a practical electric refrigeration unit, which later became the basis for the Kelvinator.
Kelvinator later merged with Nash and then with Hudson to become AMC.
William C. Durant, founder of General Motors and Chevrolet founded the Frigidaire Company in 1918 to mass-produce refrigerators.
