in 1949 Chemist Emanuel Goldberg developed the first plastic pipette jars, going on to found the Nalge Company, which Goldberg named using his wife's initials: Natalie Levey Goldberg. In the 60s, their labware scientists - who were also big into hiking - took their Nalge laboratory bottles to carry water on backpacking trips, taking advantage of the bottles leak-proof and lightweight qualities.
In the 70s, the Carry In/Carry Out trend emerged when conservationists began discouraging campers from a common at the time disposal practice of burning or burying cans and glass containers. At that point, Nalge bottles had caught on with the hiking and adventuring subculture giving their then president the idea of marketing their labware products as high-quality hiking and camping essentials. With that, Nalgene Outdoor was born.
