The Thrill of the Chase
Samuel J. Wagstaff Jr. (1921–1987) amassed an extraordinary collection of 26,000 photographs between 1973 and 1984, recognizing that photography was an undervalued art form on which he might have a profound impact as a collector. He was mainly attracted to photographs that stimulated his imagination, and his taste ran toward the idiosyncratic—images that surprised him chiefly because he had never seen them before. In choosing the 147 works reproduced in this volume, Paul Martineau selected masterpieces as well as images from obscure sources: daguerreotypes, cartes-de-visite, and stereographs, plus mug shots, medical photographs, and works by unknown makers. The latter category contains s...
Wagstaff: Before and After Mapplethorpe: A Biography
Winner of the Arts Club of Washington Marfield Prize A New York Times Book Review Editors’ Choice Selection This "admiring and absorbing biography" (Deborah Solomon, The New York Times Book Review) charts Sam Wagstaff's incalculable influence on contemporary art, photography, and gay identity. A legendary curator, collector, and patron of the arts, Sam Wagstaff was a "figure who stood at the intersection of gay life and the art world and brought glamour and daring to both" (Andrew Solomon). Now, in Philip Gefter's groundbreaking biography, he emerges as a cultural visionary. Gefter documents the influence of the man who—although known today primarily as the mentor and lover of Robert Mapplethorpe—"almost invented the idea of photography as art" (Edmund White). Wagstaff: Before and After Mapplethorpe braids together Wagstaff's personal transformation from closeted society bachelor to a rebellious curator with a broader portrait of the tumultuous social, cultural, and sexual upheavals of the 1960s, '70s, and '80s, creating a definitive portrait of a man and his era.

Cryptanalysis of Number Theoretic Ciphers
At the heart of modern cryptographic algorithms lies computational number theory. Whether you're encrypting or decrypting ciphers, a solid background in number theory is essential for success. Written by a number theorist and practicing cryptographer, Cryptanalysis of Number Theoretic Ciphers takes you from basic number theory to the inner workings of ciphers and protocols. First, the book provides the mathematical background needed in cryptography as well as definitions and simple examples from cryptography. It includes summaries of elementary number theory and group theory, as well as common methods of finding or constructing large random primes, factoring large integers, and computing dis...
The Joy of Factoring
"This book is about the theory and practice of integer factorization presented in a historic perspective. It describes about twenty algorithms for factoring and a dozen other number theory algorithms that support the factoring algorithms. Most algorithms are described both in words and in pseudocode to satisfy both number theorists and computer scientists. Each of the ten chapters begins with a concise summary of its contents. This book is written for readers who want to learn more about the best methods of factoring integers, many reasons for factoring, and some history of this fascinating subject. It can be read by anyone who has taken a first course in number theory." -- Publisher website.
