This volume features substantive biographical essays on 59 women from around the world who have made significant contributions to mathematics from antiquity to the present. Designed for secondary school students and the general public, each profile describes major life events, obstacles faced and overcome, educational and career milestones--including a discussion of mathematical research in non-technical terms--and interests outside of mathematics. Although the collection includes historical women, the emphasis is on contemporary mathematicians, many of whom have not been profiled in any previous work. Also included are the contributions of minority women, including 10 African-American, Latina, and Asian mathematicians.

Alan Turing (1912-54) was a British mathematician who made history. His breaking of the German U-boat Enigma cipher in World War II ensured Allied-American control of the Atlantic. But Turing's vision went far beyond the desperate wartime struggle. Already in the 1930s he had defined the concept of the universal machine, which underpins the computer revolution. In 1945 he was a pioneer of electronic computer design. But Turing's true goal was the scientific understanding of the mind, brought out in the drama and wit of the famous "Turing test" for machine intelligence and in his prophecy for the twenty-first century. nbsp; Drawn in to the cockpit of world events and the forefront of technological innovation, Alan Turing was also an innocent and unpretentious gay man trying to live in a society that criminalized him. In 1952 he revealed his homosexuality and was forced to participate in a humiliating treatment program, and was ever after regarded as a security risk. His suicide in 1954 remains one of the many enigmas in an astonishing life story.

Fermat's Last Theorem became the Holy Grail of mathematics. Whole and colorful lives were devoted, and even sacrificed, to finding a proof. Leonhard Euler, the greatest mathematician of the eighteenth century, had to admit defeat. Sophie Germain took on the identity of a man to do research in a field forbidden to females, and made the most significant breakthrough of the nineteenth century. The dashing Evariste Galois scribbled down the results of his research deep into the night before venturing out to die in a duel in 1832. Yutaka Taniyama, whose insights would ultimately lead to the solution, tragically killed himself in 1958. On the other hand, Paul Wolfskehl, a famous German industrialist, claimed Fermat had saved him from suicide, and established a rich prize for the first person to prove the theorem. And then came Princeton professor Andrew Wiles, who had dreamed of proving Fermat's Last Theorem ever since he first read of it as a boy of ten in his local library. In 1993, some 356 years after Fermat's challenge, and after seven years of working in isolation and secrecy - "a kind of private and very personal battle I was engaged in" - Wiles stunned the world by announcing a proof, though his own journey would be far from over. Fermat's Enigma is the story of the epic quest to solve the greatest math problem of all time. A human drama of high dreams, intellectual brilliance, and extraordinary determination, it will bring the history and culture of mathematics into exciting focus for all who read it.
