Mary Sherman Morgan

Mary Sherman Morgan was born in 1921 in North Dakota and grew up on a farm during the Great Depression. Although she dreamed of becoming a scientist, financial challenges prevented her from completing college. During World War II, she worked in a factory, where her talent for chemistry was quickly recognized. She later joined Rocketdyne, becoming the company's only female rocket propulsion engineer among hundreds of men. Mary developed Hydyne, a powerful rocket fuel that was used to launch Explorer 1 in 1958, marking America's entry into the Space Age. Because much of her work was classified, few people knew about her contributions for many years. Today, Mary Sherman Morgan is celebrated as a pioneer who proved that determination, curiosity, and scientific talent can change history—even if the world doesn't recognize it right away.
