The U.S. Government statistics indicate that women’s employment increased during World War II from about 5.1 million in 1939 (26%) to just over 7.25 million (36%) in 1943. Among these women was a 21-year-old named Dorthy Vogely:
"Dorthy operates a testing machine at Timken Roller Bearing Company in Canton, Ohio. She works the 'graveyard shift", from 10:30 p.m. to 6:30 a.m... At first, the strange hours put her at odds with the world, but now she believes working in war industry has made her a new, more self-reliant person. She has more to spend on clothes and cosmetics than ever before, has more dates and more friends."
