Berta Frey (8 November 1893 – 1 February 1972) was a well-known New York weaver, who spoke and taught about weaving techniques for many years.

[1][2] During World War I (1914–18) she was an occupational therapist specializing in woodworking in the army's Walter Reed Hospital in Washington, D.C.[2] She learned handweaving at this time.

[2] In 1934, Frey, already known as an author of technical works on handweaving, attended a summer session of the Penland Weaving Institute in the Blue Ridge Mountains of North Carolina.

[3] On 8–9 April 1955 a meeting of 135 members of Ontario weaving guilds was held at the Heliconian Club in Toronto.

The group formed an advisory committee to look into setting up a provincial organization, leading to the foundation of the Ontario Handweavers & Spinners (OHS) the next year.

[9] She returned to Ontario in 1960, when she was the principal speaker at the OHS conference organized by the Ottawa Valley Weavers Guild.

[13] The Thousand Islands Arts Center ~ Home of the Handweaving Museum in Clayton, New York has an extensive collection of textiles made by Frey.
