In 1895, Ernest Bryant and Ezra Smith, two businessmen from Oskaloosa, Iowa, shared with Lennox their plans for a furnace using riveted steel for the heating surface. The furnaces used to heat homes at that time were made entirely of cast iron, which had a tendency to warp and crack after extended use and could cause smoke and coal gases to seep into houses. Bryant, Smith, and Lennox entered into an agreement in which Lennox made the iron castings used for the grates, fronts, and other parts of their steel furnaces. When Bryant and Smith were unable to pay Lennox for the iron castings after losing their financial backing, Lennox took over their patents and reworked their original design. Marketing the furnaces under his own Torrid Zone brand name, Lennox' furnace business grew and became a success.
Lennox sold his furnace business in 1904 to a group of local Marshalltown businessmen, led by David Windsor Norris, a local business and civic leader and owner of the local newspaper, the Marshalltown Times Republican. According to company records, the sales price was $57,789.14. Norris began operating the company under the name Lennox Furnace Company. The company grew across the United States throughout the first half of the 20th century, expanded into the air conditioning industry in the early 1950s, and was renamed Lennox Industries. Expanding further into commercial refrigeration and international markets, Lennox Industries became Lennox International Inc. in 1984. After 95 years of private ownership by the Norris family, the company now known as Lennox International made its initial public offering in 1999 and is currently traded on the New York Stock Exchange under the symbol "LII."
