In 1903, Richard S. Reynolds went to work for his uncle (tobacco king R.R. Reynolds) where they used thin sheets of tin-lead to wrap cigarettes & loose tobacco to protect them from moisture.
In 1919, after mastering the technique with foil, R.S. Reynolds opened his own business, the U.S. Foil Co. in Louisville, KY.
Candy makers found that the tin wraps gave a tighter seal to the hard candy than wax paper, so they started buying the wraps too.
When the price of aluminum began to drop in the late '20s, R.S. Reynolds adapted the tin-lead wrap to use aluminum. At the time, aluminum was a fairly new metal and hadn't really been used.
Reynolds believed that the lightweight and noncorrosive metal was the wave of the future and expanded is business to be the first to offer home owners such things as: aluminum siding, windows, boats, pots & pans and kitchen utensils.
His most popular product, however, was the 1947 development of 0.0007 inch thick aluminum foil. It conducted heat rapidly, was lightweight, non-rusting, nontoxic, paper thin and sealed in moisture. When refrigerating foods it turned out to be odor-proof and light-proof.
Few products for the home were more rapidly and positively welcomed than aluminum foil.
