Stephanie Louise Kwolek is an American chemist who invented poly-paraphenylene terephthalamide, better known as Kevlar. She was born in the Pittsburgh suburb of New Kensington, Pennsylvania. In 1964, in anticipation of a gasoline shortage, her group began searching for a lightweight yet strong fiber to be used in tires. The polymers she had been working with at the time formed liquid crystal while in solution, something unique to those polymers at the time. However, Kwolek persuaded technician Charles Smullen to test her solution. She was amazed to find that the new fiber would not break when nylon typically would.

Within the origin of one of the world’s most iconic superheroes hides a fascinating family story—and a crucial history of feminism in the twentieth-century. “Everything you might want in a page-turner … skeletons in the closet, a believe-it-or-not weirdness in its biographical details, and something else that secretly powers even the most “serious” feminist history—fun.” —Entertainment Weekly The Secret History of Wonder Woman is a tour de force of intellectual and cultural history. Wonder Woman, Jill Lepore argues, is the missing link in the history of the struggle for women’s rights—a chain of events that begins with the women’s suffrage campaigns of the early 1900s and ends with the troubled place of feminism a century later. Lepore, a Harvard historian and New Yorker staff writer, has uncovered an astonishing trove of documents, including the never-before-seen private papers of Wonder Woman’s creator, William Moulton Marston. The Marston family story is a tale of drama, intrigue, and irony. In the 1920s, Marston and his wife brought into their home Olive Byrne, the niece of Margaret Sanger, one of the most influential feminists of the twentieth century. Even while celebrating conventional family life in a regular column that Marston and Byrne wrote for Family Circle, they themselves pursued lives of extraordinary nonconformity. Marston, internationally known as an expert on truth—he invented the lie detector test—lived a life of secrets, only to spill them on the pages of Wonder Woman. Includes a new afterword with fresh revelations based on never before seen letters and photographs from the Marston family’s papers, and 161 illustrations and 16 pages in full color.

Maiman was a graduate of the University of Colorado, which awarded him a B.S. in engineering physics in 1949. Later, he received his Ph.D. in physics in 1955 from Stanford University and began work at the Hughes Research Laboratory (HRL). There he concentrated on creating a device capable of converting mixed frequency electromagnetic radiation into highly amplified and coherent light of discrete frequency. Maiman later found that the accepted calculations of the fluorescence quantum efficiency of ruby were wrong and that the material could be used for his research. His persistence with ruby eventually paid off, for on May 16, 1960, the device he built using it became the world's first operable laser.
