In 1904, Frank Manny and Lewis Hine made their first trip to Ellis Island. Manny and Hine also wanted to use the photographs of Ellis Island as teaching tools for the students who attended the Ethical Culture School. Many of them were the children of newly arrived immigrants, and Manny wanted them to be proud of their heritage. Since the main rooms at Ellis Island were dark, Hine needed a flash to provide more light. This was provided by flash powder, made of a combination of magnesium and a chemical called potassium chlorate, which was spread over a metal pan. “By that time most of the group,” Hine recalled, “were either silly or stony or weeping with hysteria because the bystanders had been busy pelting them with advice and comments, and the climax came when the people raised the flash pan aloft over them and they waited, rigidly, for the blast.
