His investment was a brilliant young hat maker, Harry Rolnick, who was operating a small hat factory. E.R. Byer was one of Rolnick's customers and was so impressed by his professionalism, and devotion to quality that in 1927 the firm of Byer-Rolnick was founded in Dallas, Texas. The company produced men's felt hats in Western and Dress stylings, both were marketed under the newly created brand name "Resistol Hats," meaning to resist- all weather.
