Etan Kalil Patz was an American boy who was six years old on May 25, 1979, when he disappeared on his way to his school bus stop in the SoHo neighborhood of Lower Manhattan. His disappearance helped launch the missing children movement, which included new legislation and new methods for tracking down missing children. Several years after he disappeared, Patz was one of the first children to be profiled in the "Photo on a milk carton" campaigns of the early 1980s. In 1983, President Ronald Reagan designated May 25—the anniversary of Etan's disappearance—as National Missing Children's Day in the United States.
