The Brilliant Calculator by Jan Lower
Call Number: X 92 CLARKE, E.
Long before calculators were invented, little Edith Clarke devoured numbers, conquered calculations, cracked puzzles, and breezed through brainteasers. Edith wanted to be an engineer to use the numbers she saw all around her to help build America. When she grew up, no one would hire a woman engineer. But that didn t stop Edith from following her passion and putting her lightning-quick mind to the problem of electricity.
