## Ebenezer ButterickDied 31 Mar 1903 at age 76 (born 29 May 1826).American manufacturer who is regarded as the inventor of graded paper patterns for clothing (1859), first sold in Sterling in Jun 1863. Formerly, a sewer had to enlarge or reduce from one standard pattern to make the required size. As a tailor, Butterick understood the need, and filled it by supplying tissue paper patterns in sizes. At first, these graded sewing patterns were cut and folded by members of his family and sold from their home in Sterling, Massachusetts. The business grew quickly, and in 1869 he moved to New York City. A box of one hundred patterns were sold at a wholesale price of $10 (retail $25). Also in 1869, he founded Metropolitan, a fashion magazine, to promote pattern sales. In the following years, he established subsidiary offices in all important centres in the U.S. and abroad.« |
