Carl C. Jantzen and John C. Zehntbauer founded the Portland Knitting Company in 1910 as a retail store selling knitted products (i.e. sweaters, hosiery, jackets). Carl Jantzen later invented an automated circular knitting machine that allowed the company to make light-weight materials for swimsuits. In 1916, the company first used the name Jantzen as their trademark and went on to specialize in swimsuits.
