Toastmaster toaster invented by Charles P. Strite and manufactured by the Waters-Genter Company of Minneapolis circa 1921. The Toastmaster was the world’s first automatic, pop-up electric toaster that could heat both sides of a slice of bread simultaneously, eliminating the need for manual flipping.  The two side levers allowed users to submerge the bread and initiate the heating process, as well as to set the toasting time according to personal taste.
