The kits story begins in the late 1800s when The Burroughs Wellcome medical manufacturing company began packaging medications and dressings in small cases for use in the field. These medical kits were used by the likes of Admiral Peary and Theodore Roosevelt, and with such great men carrying this product the word of its quality spread fast. At the turn of the century, with the development of cars, trucks, railways, and telephones and telegraphs, Burroughs Wellcome was invited to a forum. The world was changing, medicine was changing, and a certain customer needed a mass production of standardized antiseptics, medications, and dressings. And so Burroughs Welcome created what would become the Pac-Kit. Of course, the Pac-Kit would later develop into its own company by the 1940s. When, in 1970s, the federal government expanded its role in the regulation of medical products, Pac-Kit was the advisor for the creation and implementation of the Quality Assurance program.
