From The Delineator, summer 1903:
The Delineator was published by Butterick, the sewing pattern company, and included fashion articles and pictures, along with short stories and other articles. In one 1903 issue, there is a mention of the recent passing of Ebenezer Butterick, who founded the Butterick company in 1863 — and invented the graded paper sewing pattern.
The Butterick company still exists, but it is now part of McCall Pattern Company (which I think has itself been acquired by some other firm). Butterick patterns, for some weird reason, always seem to have annoying and confusing directions, compared to other pattern companies. I don’t know why. I’m glad they still exist, though.
