It all started with an idea of preserving milk as a safe and convenient source of dairy. After a $15,000 investment in 1885, the Helvetica Milk Condensing Company was formed. One of the early brands, PET® Evaporated Cream, became the most memorable. This evaporated milk supplied former president Teddy Roosevelt’s Rough Riders and soldiers in both world wars. In 1923, the company officially changed its name to the PET Milk Company.
