Railroad Engineer Olive Dennis

"When Olive Dennis was young, girls were expected to be sewing, cooking, and cleaning. But Olive was busy imagining, designing, and building everything from a wooden dollhouse to a model streetcar with working parts. When she grew up, Olive continued to defy expectations, earning a civil engineering degree and becoming the Baltimore & Ohio Railroad's first female engineer. Her genius for inventing improvements based on her keen observations of passengers' needs and problems led her to the assignment of a lifetime: designing a luxury train that would change rail travel forever."
