I used to live in a neighborhood boasting several martial-arts schools, and always liked walking by at night to see them all lit up and peopled with serious-looking little girls and boys in their crisp white gis. But it wasn’t until recently that I heard about the woman who was partially responsible for making sure that girls got an equal shake in martial-arts training and competition. Rusty Kanokogi, who died in November, 2009 at the age of 74, was the first woman to earn a seventh-degree black belt in judo. But perhaps more important, she was a pioneer in making the sport accessible to women in a time before Title IX.
