History
In 1924,[5] William Calvert Chaney (1888–1965),[6] who worked under Henry Woltman at the Mayo Clinic, seems to have been the first to publish a description of the sign, but Woltman had no authorship and was not mentioned in Chaney's manuscript. The eponym "Woltman's sign of myxedema" was first published in 1956 at the time of Woltman's retirement.[7]
