"Margaret Olofsson Bergman was a Pacific Northwest weaver, teacher, and designer. During the 1930s, Bergman designed and patented two looms: the Bergman Suitcase loom and the Bergman Floor loom. Each loom was designed with unique folding frames that enabled the loom to collapse even when fully warped. Her husband John and son Arthur built looms at their home in Breidablik, now part of Poulsbo, Washington."@en .
