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 didnt stop Edith from following her passion and putting her lightning-quick mind to the problem of electricity. But the calculations took so long! Always curious, Edith couldnt help thinking of better ways to do things. She constructed a calculator from paper that was ten times faster than doing all that math by hand! Her invention won her a job, making her the first woman electrical engineer in America. And because Edith shared her knowledge with others, her calculator helped electrify America, bringing telephones and light across the nation.
