The brand featured a logo image of a young woman, dressed in a red one-piece swimsuit and bathing hat, assuming a diving posture with outstretched arms and an arched back.

Carl Jantzen died from a heart attack on May 30, 1939[2] while passing through Sherman Hill, Idaho returning from a round-the-world tour.

[1] The story, as told by Zehntbauer in the company paper, the Jantzen Yarns: I waited on him and took his order for these rowing trunks, to be made of a stitch like that of a cuff of a sweater so that they would stay up without a drawstring.

When he came back, he came into the store and told us that it was heavy and one could not swim well in it, but that he was well satisfied because it was so much warmer than any suit that he had ever had before and that it made ocean bathing a pleasure.

We discussed this between ourselves and decided that we would order a needle bed for our sweater machine that would be fine enough to knit a rib-stitch bathing suit in a weight that would be comfortable.

[3]The one-piece garment of pure wool that Carl Jantzen designed eventually became the prototype for the rib-stitch swimsuits that were first produced in 1915.

The cover of the advertisements featured the "Red Diving Girl", which became adopted as the logo of the company and recognizable worldwide.

Mr. Dodson was manager of the Broadway retail store at the time, and I remember distinctly the twinkle in his eye as he suggested the use of the name in our advertising.

During the inter-war years of the late 1920s and early 1930s the company established overseas manufacturing facilities and sales teams, notably in Europe.

In the 1950s, fashion designer Maurice Levin popularized the trend of the color pink worn on men through the Jantzen brand.

Jantzen also introduced a Trikini, combining a string bikini worn underneath a lacy, semi-transparent maillot.
