The DuPont Company opens a mill in Keokuk, Iowa to produce gunpowder. Although dynamite was more widely used for construction purposes, coal-miners preferred black powder because it only loosened the coal instead of pulverizing it to dust the way dynamite did. With so many factories and steam locomotives using coal to create steam power, and homes using coal for heat, the need for coal was great and would continue so for years to come. The plant produced gunpowder until 1948, a time that marked the beginning of the modern auto collision repair industry, and the emergence of DuPont as a major supplier of automotive refinish paint products.
