In the winter of 1961-1962, Bill Kirschner (1918-2006) of Vashon Island invents a fiberglass ski. (However, a Swiss ski manufacturer patented a fiberglass skis in 1958, so Kirschner was not its first inventor.) Kirschner "wet wraps" fiberglass around a slim spruce core and places it in a pressure mold to produce a strong recreational ski with lots of rebound, priced (approximately $80) between wood and metal skis.

The first production model, The Holiday, was introduced in 1965 by Kirschner's K2 Corporation (named after Kirschner and his brother Don and the world's second highest mountain).

Kirschner gained his knowledge of fiberglass through the manufacture of easy-to-clean animal cages. By 1968, K2 had sold 19,000 sets of skis. K2 gained wide recognition when Marilyn Cochran won the 1968 World Cup gold medal on a pair of competition K2s designed by Kirschner. By 1991, K2 had sold 400,000 pairs of skis, half of them in the United States. Kirschner sold the company in 1969.

Note. Woog states that Kirschner invented the fiberglass ski in 1961. However, a Swiss producer of high-tech skis, Gaston Haldemann, patented a fiberglass ski (patent no. 346468) on November 24, 1958. Haldemann sold his license to produce fiberglass skis to another Swiss firm, Rossignol, that year. This information appears in a paper, "Ski Industry in Switzerland," by John (Hans) Schwendener and Luzi Hitz with additional information supplied by ski collector Luzi Hitz, Corseaux, Switzerland, to on January 25, 2005. This file was corrected on January 25, 2005.
