Breaking the Codes is a cultural history of the fin-de-siecle that uses the "problem" of the criminal woman to examine both the debates around the appropriate place of women in French society and the ways in which issues of gender were central to the most important cultural transformations of the period. The author asserts that "female criminality" was a code that condensed and obscured larger concerns. For example, to what degree and in what ways did the symbolic overtones of female criminality connect to the substantive issues that appeared over and over again in the stories of women's crime? How were the crimes of domestic violence, infanticide, and abortion interpreted in the context of broader debates about divorce, depopulation, sexuality, and women's roles in the public sphere? What was the role of expert commentary - from the forensic psychiatrist, the criminologist, the legal scholar - in producing a normative code for female behavior? And how did this code accommodate or resist the newly recognized voice of popular opinion and changing notions of citizenship? This study demonstrates both the inadequacy of the categories of public and private as they have been conventionally used to segregate the subjects of historical inquiry and the artificiality of the boundaries between high and low culture. Instead, it moves between domestic life and public courtrooms, between social science literature and popular journalism, analyzing the complex responses to female crime among different constituencies and through different genres. In so doing, the author sheds light on various overlapping processes of cultural negotiation in a period of profound change.

The award-winning New York Times bestseller about the American women who secretly served as codebreakers during World War II--a "prodigiously researched and engrossing" (New York Times) book that "shines a light on a hidden chapter of American history" (Denver Post). Recruited by the U.S. Army and Navy from small towns and elite colleges, more than ten thousand women served as codebreakers during World War II. While their brothers and boyfriends took up arms, these women moved to Washington and learned the meticulous work of code-breaking. Their efforts shortened the war, saved countless lives, and gave them access to careers previously denied to them. A strict vow of secrecy nearly erased their efforts from history; now, through dazzling research and interviews with surviving code girls, bestselling author Liza Mundy brings to life this riveting and vital story of American courage, service, and scientific accomplishment.

Ever since humans first began to communicate, we’ve had secrets to keep — secrets of state, war, business, or the heart. From the moment the first secret message was sent, others were busy trying to decipher it. By rearranging, substituting, or transposing symbols, any message can be encoded or decoded — if you know how. Secrets of Making and Breaking Codes is a practical field manual designed to teach you the basic mechanics of enciphering and deciphering communications. The author has used his extensive knowledge of and experience in electronic communications and languages — as well as his decades of fascination with secret codes — to demystify the field of cryptology. Hamilton Nickels uses plain, uncomplicated English and simple, workable systems that rely on neither advanced mathematics, nor on ethereal philosophies. This is the only hands-on guide to both the simplest cipher schemes — that need little more than scratch paper and a pencil to crack — as well as more sophisticated codes that use one-time code books, pocket calculators, and the most advanced computer-based systems used by the military and diplomatic corps of most governments. Letting the wrong eyes see a secret message can often make the difference between victory and defeat, success and failure, life and death. Secrets of Making and Breaking Codes will make mastering codes easier.
