When Annie Jump Cannon was hired to work at the Harvard Observatory, women couldn't be REAL astronomers. Instead, while men used the telescope, women acted as human computers, analyzing and studying the data. Cannon was assigned a difficult task: figuring out how to classify all the new stars that photographs and more powerful telescopes were identifying. Not only did she develop a classification system that is still used today, but she also classified thousands of stars -- to this day, she holds the record for identifying more stars than anyone else in the world! And when she was 75, Harvard at long last gave her the title of Doctor of Astronomy.
Author Carole Gerber focuses on Cannon's love of astronomy as a vehicle for talking about the remarkable accomplishments of this groundbreaking astronomer.
