On this day in 1912, Juliette Gordon Low gathered a group of girls in Savannah, Ga., and formed the first troop of what is today known as the Girl Scouts. Low, an avid swimmer, rower and tennis player, and her troop went on hiking and camping trips, played basketball, learned first aid and participated in community-service activities. The allure was immediate, and by 1920, the Girl Scouts had more than 70,000 members all over the country. In 2013, there were more than 3.2 million Girl Scouts in the United States, organized troops in 92 countries and more than 59 million American women could be counted as alumni. Some notable former Girl Scouts include Rebecca Lobo, Jackie Joyner-Kersee, Nancy Lopez, Janet Evans, Bonnie Blair and Venus Williams. Perhaps known best and most adoringly for their annual sale of cookies, that tradition dates back to 1917 when a troop in Oklahoma began selling homemade goodies in their school cafeteria to raise money for the troop. In 2013, 200 million boxes of cookies were sold nationwide.
