“On the afternoon of May 28, 1903, Leoti Blaker, a young Kansan touring New York City, boarded a Fifth Avenue stagecoach at 23rd Street and settled in for the ride. The coach was crowded, and when it jostled she noticed that the man next to her settled himself an inch closer to her. She made a silent assessment: elderly, elegantly dressed, ‘benevolent-looking.’ The horse picked up speed and the stage jumped, tossing the passengers at one another again, and now the man was touching her, hip to hip, shoulder to shoulder. When he lifted his arm and draped it low across her back, Leoti had enough. In a move that would thrill victim of modern-day subway harassment, she reached for her hatpin—nearly a foot long—and plunged it into the meat of the man’s arm. He let out a terrible scream and left the coach at the next stop.
‘He was such a nice-looking old gentleman I was sorry to hurt him,’ she told the New York World. ‘I’ve heard about Broadway mashers and “L” mashers, but I didn’t know Fifth Avenue had a particular brand of its own…. If New York women will tolerate mashing, Kansas girls will not.’” There’s more about women wielding hat pins and umbrellas at Smithsonian Magazine.
