If science has the equivalent of a Bloomsbury group, it is the five men born at the turn of the 20th century in the same neighborhood in Budapest: Theodore von Karman, Leo Szilard, Eugene Wigner, John von Neumann, and Edward Teller. Through immigration from Hungary to Germany to the United States, they remained friends and continued to work together and influence each other throughout their lives. As a result, their work was integral to some of the most important scientific and political developments of the 20th century. They were an extraordinary group of talents: Wigner won a Nobel Prize in theoretical physics without ever having taken a formal college-level physics course, Szilard was the first to see that a chain reaction based on neutrons was possible but left physics to try to restrict nuclear arms, von Neumann could solve problems in his head for which most people needed computers, von Karman became the first director of NASA's Jet Propulsion Lab, and Teller was the father of the hydrogen bomb, whose name is now synonymous with the controversial "Star Wars" defense initiative of the 1980s. Each was fiercely opinionated and politically active, reactionaries against the fascism and anti-Semitism with which they had grown up. Istvan Hargittai, as a young Hungarian physicist, was able to get to know these great men in their later years, and the depth of information and human interest in this book is the result of his personal relationships with the subjects, their families and their contemporaries.
