• March is Women’s History Month

    Did you know Elwood Haynes’ wife, Bertha, was also a “Pioneer”? After her husband destroyed the family kitchen with an experiment for his horseless carriage, Bertha insisted he move his “shop” elsewhere. This set in motion the creation of the first gas-powered automobile. Her distaste for polishing cutlery also prompted him to develop stainless steel silverware for her personal use. Thank you, Mrs. Haynes, for being an inspiration for inventions that improve our daily lives and for supporting your husband to establish a company that still bears your name today.
