In 1876 Dr. Gustav Jaeger, zoologist and physiologist at the University of Stuttgart, began advocating the wearing of rough animal fibers, particularly undyed sheep wool, close to the skin; early customers of his “Sanitary Woollen System” included Oscar Wilde and Henry Stanley, who brought them on his expedition to Africa to search for Dr. Livingstone.

Winston Churchill claimed the soft texture of woven silk underwear was vital to his well-being; “I have a very delicate and sensitive cuticle which demands the finest covering,” he said. His wife, Clementine, told a friend that his pink underclothes “cost the eyes out of the head.”

A greenish-brown, diamond-twill, boat-neck wool sweater woven between 230 and 380 and worn by a reindeer hunter was discovered by researchers in 2013. The tunic, which was mended with two patches, had been preserved in the Norwegian Lendbreen glacier and would have fit a slender man of about 5'9". “The hunter,” said researcher Lise Bender Jørgensen, “looked after his clothing.”

“Battle Hymn of the Republic” author Julia Ward Howe complained to her sister in August 1846 about the death of her sister-in-law: “My mourning has been quite an inconvenience to me this summer. I had just spent all the money I could afford for my summer clothes and was forced to spend $30 more for black dresses,” Howe wrote. “The black clothes, however, seem to me very idle things, and I shall leave word in my will that no one shall wear them for me.”
