Book Description
The evolutionist Ernst Mayr considered August Weismann “one of the great biologists of all time.” Yet the man who formulated the germ plasm theory—that inheritance is transmitted solely through the nuclei of the egg and sperm cells—has not received an in-depth historical examination. August Weismann reintroduces readers to a towering figure in the life sciences. In this first full-length biography, Frederick Churchill situates Weismann in the swirling intellectual currents of his era and demonstrates how his work paved the way for the modern synthesis of genetics and evolution in the twentieth century. In 1859 Darwin’s tantalizing new idea stirred up a great deal of activity and turmoil in the scientific world, to a large extent because the underlying biological mechanisms of evolution through natural selection had not yet been worked out. Weismann’s achievement was to unite natural history, embryology, and cell biology under the capacious dome of evolutionary theory. In his major work on the germ plasm (1892), which established the material basis of heredity in the “germ cells,” Weismann delivered a crushing blow to Lamarck’s concept of the inheritance of acquired traits. In this deeply researched biography, Churchill explains the development of Weismann’s pioneering work based on cytology and embryology and opens up an expanded history of biology from 1859 to 1914. August Weismann is sure to become the definitive account of an extraordinary life and career.

Book Description
This unique book looks at the biology of aging from a fundamentally new perspective, one based on evolutionary theory rather than traditional concepts which emphasize molecular and cellular processes. The basis for this approach lies in the fact that natural selection, as a powerful determining force, tends to decline in importance with age. Many of the characteristics we associate with aging, the author argues, are more the result of this decline than any mechanical imperative contained within organic structures. This theory in turn yields the most fruitful avenues for seeking answers to the problem of aging, and should be recognized as the intellectual core of gerontology and the foundation for future research. The author ably surveys the vast literature on aging, presenting mathematical, experimental, and comparative findings to illustrate and support the central thesis. The result is the first complete synthesis of this vital field. Evolutionary biologists, gerontologists, and all those concerned with the science of aging will find it a stimulating, strongly argued account.

Book Description
The great evolutionist Mayr elucidates the subtleties of Darwin’s thought and that of his contemporaries and intellectual heirs—A. R. Wallace, T. H. Huxley, August Weisman, Asa Gray. Mayr has achieved a remarkable distillation of Darwin’s scientific thought and his legacy to twentieth-century biology.

Book Description
Historians of science have long noted the influence of the nineteenth-century political economist Thomas Robert Malthus on Charles Darwin. In a bold move, Piers J. Hale contends that this focus on Malthus and his effect on Darwin’s evolutionary thought neglects a strong anti-Malthusian tradition in English intellectual life, one that not only predated the 1859 publication of the Origin of Species but also persisted throughout the Victorian period until World War I. Political Descent reveals that two evolutionary and political traditions developed in England in the wake of the 1832 Reform Act: one Malthusian, the other decidedly anti-Malthusian and owing much to the ideas of the French naturalist Jean Baptiste Lamarck. These two traditions, Hale shows, developed in a context of mutual hostility, debate, and refutation. Participants disagreed not only about evolutionary processes but also on broader questions regarding the kind of creature our evolution had made us and in what kind of society we ought therefore to live. Significantly, and in spite of Darwin’s acknowledgement that natural selection was “the doctrine of Malthus, applied to the whole animal and vegetable kingdoms,” both sides of the debate claimed to be the more correctly “Darwinian.” By exploring the full spectrum of scientific and political issues at stake, Political Descent offers a novel approach to the relationship between evolution and political thought in the Victorian and Edwardian eras.

Book Description
Two horror films were nominated for the Academy Award for Best Picture in 2018, and one of them—The Shape of Water—won. Since 1990, the production of horror films has risen exponentially worldwide, and in 2013, horror films earned an estimated $400 million in ticket sales. Horror has long been the most popular film genre, and more horror movies have been made than any other kind. We need them. We need to be scared, to test ourselves, laugh inappropriately, scream, and flinch. We need to get through them and come out, blinking, still in one piece. Lost in the Dark: A World History of Horror Film is a straightforward history written for the general reader and student that can serve as a comprehensive reference work. The volume provides a general introduction to the genre, serves as a guidebook to its film highlights, and celebrates its practitioners, trends, and stories. Starting with silent-era horror films and ending with 2020’s The Invisible Man, Lost in the Dark looks at decades of horror movies. Author Brad Weismann covers such topics as the roots of horror in literature and art, monster movies, B-movies, the destruction of the American censorship system, international horror, torture porn, zombies, horror comedies, horror in the new millennium, and critical reception of modern horror. A sweeping survey that doesn’t scrimp on details, Lost in the Dark is sure to satisfy both the curious and the completist.

Book Description
A Jewish man recounts his experience as a little boy in Paris during World War II and the Holocaust, as well as his escape and survival in this memoir. On the nights of July 16 and 17, 1942, French police rounded up eleven-year-old Joseph Weismann, his family, and 13,000 other Jews. After being held for five days in appalling conditions in the Vélodrome d’Hiver stadium, Joseph and his family were transported by cattle car to the Beaune-la-Rolande internment camp and brutally separated: all the adults and most of the children were transported on to Auschwitz and certain death, but 1,000 children were left behind to wait for a later train. The French guards told the children left behind that they would soon be reunited with their parents, but Joseph and his new friend, Joe Kogan, chose to risk everything in a daring escape attempt. After eluding the guards and crawling under razor-sharp barbed wire, Joseph found freedom. But how would he survive the rest of the war in Nazi-occupied France and build a life for himself? His problems had just begun. Until he was 80, Joseph Weismann kept his story to himself, giving only the slightest hints of it to his wife and three children. Simone Veil, lawyer, politician, President of the European Parliament, and member of the Constitutional Council of France—herself a survivor of Auschwitz—urged him to tell his story. In the original French version of this book and in Roselyne Bosch’s 2010 film La Rafle, Joseph shares his compelling and terrifying story of the Roundup of the Vél’ d’Hiv and his escape. Now, for the first time in English, Joseph tells the rest of his dramatic story in After the Roundup. “As few others manage, Joseph Weismann’s memoir captures the tension between the great communal torment and the unique personal repercussions of those who endured the Holocaust. This is a boy’s story, except that boy is in hell, faces it, and survives.” —Thomas Keneally, author of Schindler’s List “Extraordinary . . . and timely. Joseph Weismann’s compelling account of his escape from an internment camp after the notorious Winter Velodrome roundup of Parisian Jews in July 1942 is both a vivid recreation of childhood (he was 11 years old when he spent a tenacious six hours crawling through a barbed wire fence to make his getaway) and a powerful insight into what it is like to be on the receiving end of the demonization of a race or religion.” —Peter Grose, author of A Good Place to Hide
