Three attorneys represented the state before the U.S. Supreme Court, including Boston-based attorney Louis D. Brandeis. He authored a brief of more than 115 pages, the vast majority compiled of various social science data and literature that documented the damaging health effects on women from working long hours. The U.S. Supreme Court recognized Brandeis by name in its opinion, which is quite unusual: “In the brief filed by Mr. Louis D. Brandeis for the defendant in errors is a very copious collection of all these matters, an epitome of which is found in the margin.” Brandeis’s heavy reliance on social science and other non-legal data formed part of the basis of what became known as “Brandeis briefs.”
