Accessible et riche, inventive sur le plan de la recherche documentaire comme dans la réflexion, cette histoire des sexualités propose de retracer les grandes étapes et les évolutions des normes et des mentalités. C'est à partir du croisement des recherches récentes que se dessine cette nouvelle histoire, prenant en compte aussi bien l'âge, le sexe, l'orientation sexuelle, que la légitimité des partenaires et le contexte général. Dans la lignée des travaux de Michel Foucault, la sexualité y est présentée comme un fait éminemment culturel, sensible aux évolutions économiques, religieuses et scientifiques, qui structure les cadres mentaux et nourrit l'imaginaire. Plus que jamais, la sexualité est devenue un domaine incontournable en histoire, en s'emparant du vocabulaire politique : égalité, domination, discrimination, liberté, libération, révolution.
A ce jour, aucun ouvrage n'était allé aussi loin dans l'étude et l'explication de ce qui n'est pas seulement un lieu du temple mais aussi un symbole fondamental de celui-ci, puisqu'il révèle l'essence-même de la fonction de Maîtrise et du travail en loge.
Je me suis donc construite contre mes géniteurs, parcours douloureux mais oh! combien formateur.
En grande section de Maternelle, je découvris qu'il n'y a que deux opérations fondamentales : l'addition et la soustraction desquelles participent la multiplication et la division. Au lieu de m'encourager dans mes observations, mon scientifique de père fêla ma confiance sans pour autant altérer mon opiniâtreté native ni interrompre mes investigations cérébrales.
Les bonnes fées ne se sont pas penchées sur le berceau, pourtant doré, de la petite fille où sont épinglés les mots « Je ne suis pas belle, je ne ressemble à personne », nous révèle d'emblée Anne Steinberg-Viéville.
Mémoires d'une étrangère est un récit autobiographique fort, ne craignant ni de choquer ni de déranger du moment qu'il y va et de la survie de l'auteur et de son désir de transmettre cette soif inextinguible de découvertes et de recherches alliée à un puissant amour de la vie. Une belle revanche sur l'enfance, sur le silence, sur le temps et qui nous invite à réveiller notre corps aussi bien que notre esprit.
Avec concision, humour et sincérité, Anne Steinberg-Vieville se livre sans retenue !
« Je ne suis pas belle, je ne ressemble à personne. »
C'est par ces mots que mon géniteur accueillit ma venue au monde. Épinglés sur mon berceau, ils furent sans doute dictés par l'ironie, familière à cet homme devenu père à l'âge d'être grand-père mais inapte à de tendres sentiments.

Né en Allemagne en 1909, résistant de l'intérieur avant d'être maquisard, apatride et légionnaire avant d'être Français, Gerhard Steinberg fut un combattant pour ne pas devenir une victime de l'Histoire. La petite Antigone, qui sommeille en moi, a de qui tenir : elle sait qu'elle opterait pour le fusil plutôt que pour l'étoile et la survie...
Revers de la médaille, dans le civil comme dans l'intimité, ce héros n'a pas baissé la garde : défiance et agressivité caractérisèrent sa conduite relationnelle. L'ingénieur polytechnicien, titulaire de plusieurs brevets, n'en fut pas moins parano avec ses collègues et ouvriers, comme avec les autorités de l'État, au point d'être incapable de tirer quelques bénéfices de ses inventions?; quant au tyran domestique, aux allures de statue du Commandeur, il ne suscita, sa vie durant, que crainte et terreur tant ses réactions furent aussi déconcertantes qu'inappropriées. L'admiration et la filiation intellectuelle sont des fruits posthumes...
À PROPOS DE L'AUTEUR
Anne Steinberg-Viéville tient aussi un blog, dont on peut tirer son portrait intellectuel : loin de toute didactique, elle propose d'étonner l'oeil de l'amateur d'art ; sa méthode souvent comparatiste et son regard très mathématique donnent à voir des merveilles secrètement dissimulées par les artistes ; en cérébrale, elle commence par la rédaction des textes, qu'elle enregistre, puis illustre au moyen d'images fixes ; en geek, elle réalise montage et synchronisation ; en pollinisateur des savoirs, elle diffuse ses points de vue sur Internet.
Los Angeles, de nos jours et tout au long du XXe siècle Alors qu´elle prépare son déménagement en maison de retraite, la célèbre avocate des droits de l´homme Elaine Greenstein retrouve dans ses vieux papiers une carte de visite qui laisse supposer que sa soeur jumelle Barbara, disparue depuis plus de soixante ans, aurait été retrouvée de nombreuses années plus tôt.

Jusqu´au dénouement tragique de cette relation triangulaire.
Alors qu´Elaine est au crépuscule de sa vie, quelle place reste-t-il dans son univers pour Barbara ? Malgré la douleur de l´absence, n´a-t-elle pas été plus épanouie sans ce point de comparaison permanent ? Après toutes ces années, a-t-elle réellement envie de retrouver cette soeur disparue ?
Avi Steinberg is stumped. After defecting from yeshiva to Harvard, he has only a senior thesis essay on Bugs Bunny to show for his effort. While his friends and classmates advance in the world, he remains stuck at a crossroads, unable to meet the lofty expectations of his Orthodox Jewish upbringing. And his romantic existence as a freelance obituary writer just isnt cutting it. Seeking direction--and dental insurance--Steinberg takes a job as a librarian in a tough Boston prison.
The prison library counter, his new post, attracts con men, minor prophets, ghosts, and an assortment of quirky regulars searching for the perfect book and a connection to the outside world. Theres an anxious pimp who solicits Steinbergs help in writing a memoir. A passionate gangster who dreams of hosting a cooking show titled Thug Sizzle. A disgruntled officer who instigates a major feud over a Post-it note. A doomed ex-stripper who asks Steinberg to orchestrate a reunion with her estranged son, himself an inmate. Over time, Steinberg is drawn into the accidental community of outcasts that has formed among his bookshelves -- a drama he recounts with heartbreak and humor. But when the struggles of the prison library -- between life and death, love and loyalty -- become personal, Steinberg is forced to take sides.
Running the Books is a trenchant exploration of prison culture and an entertaining tale of one young mans earnest attempt to find his place in the world while trying not to get fired in the process.

On Park Hill Avenue in New York City, almost everyone is Liberian. Most people know one another; if not by name, then by face. And yet neighbours do not ask one another what they did in Liberia, for the question is considered an accusation. Many people here fled Liberia's brutal civil war, a conflict that claimed the lives of one in fourteen Liberians. The question of who is responsible is a bitter one. Jacob Massaquoi arrived on Park Hill Avenue in 2002 limping heavily. Before he had been there a week, a hundred stories abounded about his injury. By this time Rufus Arkoi was the acknowledged leader of New York's Liberians, a man who had sat out the war in America, but who harboured hopes of one day returning home to run for president. Within a year the two men were locked in a conflict that threatened to consume the community. The suspicions and accusations the residents had bottled up for years exploded at once. To observers it appeared that this enclave of exiles was frozen at the time of their flight, restarting a war that had ended back home. Jonny Steinberg spent two years in New York shadowing Rufus and Jacob, eventually journeying to Liberia to piece together their biographies from the people who once knew them. What emerges is a story of a horrific and heart-wrenching civil war, of a deeply troubled relationship between America and West Africa, of personal ambition wrestling with moral responsibility, of memory wrestling with forgetfulness and of the quest to be human in a world losing its humanity. Mixing history, reportage and a wealth of extraordinary personal stories Jonny Steinberg takes up the tale of a fractured African nation and its diaspora to remarkable effect. Little Liberia is a unique and important book, told with clarity and compassion, by one of our best and brightest young writers.
At the end of a steep gravel road in one of the remotest corners of South Africa's Eastern Cape lies the village of Ithanga. Home to a few hundred villagers, the majority of them unemployed, it is inconceivably poor. It is to here that award-winning author Jonny Steinberg travels to explore the lives of a community caught up in a battle to survive the ravages of the greatest plague of our times, the African AIDS epidemic. He befriends Sizwe, a young local man who refuses to be tested for Aids despite the existence of a well-run testing and anti-retroviral programme. It is his deep ambivalence, rooted in his deep sense of the cultural divide, that becomes the key to understanding the dynamics that thread their way through a complex and traditional rural community.
As Steinberg grapples to get closer to finding answers that remain maddeningly just out of reach, he realizes that he must look within himself to unravel certain riddles....

In the spring of 1999, in the beautiful hills of the KwaZulu-Natal Midlands, a young white farmer is shot dead on the dirt road running from his father's farmhouse to his irrigation fields. The murder is the work of assassins rather than robbers; a single shot behind the ear, nothing but his gun stolen, no forensic evidence like spent cartridges or fingerprints left at the scene. Journalist Jonny Steinberg travels to the Midlands to investigate. Local black workers say the young white man had it coming. The dead man's father says that the machinery of a political conspiracy has been set into motion, that he and his neighbours are being pushed off their land. Initially thinking that he is to write about an event in the recent past, Steinberg finds that much of the story lies in the immediate future. He has stumbled upon a festering frontier battle, the combatants groping hungrily for the whispers and lies that drift in from the other side. Right from the beginning, it is clear that the young white man is not the only one who will die on that frontier, and that the story of his and other deaths will illuminate a great deal about the early days of post-apartheid South Africa. Sifting through the betrayals and the poisoned memories of a century-long relationship between black and white, Steinberg takes us to a part of post-apartheid South Africa we fear to contemplate. Midlands is about the midlands of the heart and mind, the midlands between possession and dispossession, the midlands between the past and present, myth and reality. Midlands is a tour de force of investigative journalism.
In this selection of his Business Day columns, Jonny Steinberg walks through Pollsmoor Prison on the eve of the invasion of Iraq and believes he sees in the jail's corridors why the US's impending war in the Middle East will fail. He meets a poverty-stricken old man who spends most of his state pension maintaining a black Mercedes Benz, and explains why this shows that government's welfare programme is working. He tells us why he thinks Thabo Mbeki is an Afro-pessismist and why a South Africa ruled by Tokyo Sexwale will be as riddled with corruption as Silvio Berlusconi's Italy. Steinberg has an eye for the strangeness of our fractured country. For the last five years, Steinberg has been recording the things he sees on his travels across South Africa in his fortnightly column on Business Day's leader page. Here are the best of those columns.
A country is policed only to the extent that it consents to be. When that consent is withheld, cops either negotiate or withdraw. Once they do this, however, they are no longer police; their role becomes something far murkier. Several months before they exploded into xenophobic violence, Jonny Steinberg travelled the streets of Alexandra, Reiger Park and other Johannesburg townships with police patrols. His mission was to discover the unwritten rules of engagement emerging between South Africa's citizens and its new police force. In this provocative new book, Steinberg argues that policing in crowded urban space is like theatre. Only here, the audience writes the script, and if the police don't perform the right lines, the spectators throw them off the stage. In vivid and eloquent prose, Steinberg takes us into the heart of this drama, and picks apart the rules South Africans have established for the policing of their communities. What emerges is a lucid and original account of a much larger matter: the relationship between ordinary South Africans and the government they have elected to rule them. The government and its people are like scorned lovers, Steinberg argues: their relationship, brittle, moody, untrusting and ultimately very needy.
On 9 June 2003, a 43-year-old coloured man named Magadien Wentzel walked out of Pollsmoor Prison in Cape Town. Behind him lay a lifelong career in the 28s, South Africa's oldest and most reviled prison gang, for decades rumoured to have specialised in rape and robbery. In front of him lay the prospect of a law-abiding future, and life in a household of eight adults and six children, none of whom earned a living. Jonny Steinberg met Wentzel in prison in the dying months of 2002. By the time Wentzel was released, he and Steinberg had spent more than 50 hours discussing his life experiences. The Number is an account of their conversations and of Steinberg's journeys to the places and people of Wentzel's past. Wentzel had lived a bewilderingly schizophrenic life, wandering to and fro between three worlds: the arcane universe of prison gangs, steeped in a mythology of banditry and retribution, where he was known as JR; the fringes of South Africa's criminal economy, where he lived by a string of stolen names and learned the arts of commercial fraud; and his scattered family which eked out a living int the coloured ghettos of the Cape flats. The Number visits each of those worlds in turn. It is a tale of modern South Africa's historic events seen through the eyes of the country's underclass. Surprisingly, perhaps, it is neither a story of passivity nor despair, but of beguiling ingenuity and cool cynicism. Most of all, the book is an account of memory and identity, of Wentzel's project to make some sense of his bewildering past and something worthy of his future. When Steinberg met him, Wentzel was embarking on a quest to retrieve the name he had been given at birth. He was also beginning the daunting task of gathering together the estranged children he had sired into a nuclear family. It was an eccentric and painful venture for a man with his past, but it has led him to construct an account of himself that begs to be told.
13 : La station Denfert-Rochereau du RER B
C'est une des plus ancienne gare de Paris construite en 1846. Récemment nettoyée c'est aussi un bel édifice construit en pierre de taille de calcaire lutétien. En la regardant de loin, on se rend compte qu'elle est semi-circulaire. Cette disposition est liée à un problème technique. Au début des chemins de fer pour faire retourner en sens inverse un train, il était nécessaire de lui faire faire une boucle. Ensuite, les plateformes circulaires mobiles capables de faire tourner une locomotive furent mises au point. Ces contraintes sont à l'origine de la forme générale de la gare.
In the stunning tradition of Lisa See, Maeve Binchy, and Alice Hoffman, The Tin Horse is a rich multigenerational story about the intense, often fraught bond sisters share and the dreams and sorrows that lay at the heart of the immigrant experience.
It has been more than sixty years since Elaine Greensteins twin sister, Barbara, ran away, cutting off contact with her family forever. Elaine has made peace with that loss. But while sifting through old papers as she prepares to move to Rancho Mañana--or the Ranch of No Tomorrow as she refers to the retirement community--she is stunned to find a possible hint to Barbaras whereabouts all these years later. And it pushes her to confront the fierce love and bitter rivalry of their youth during the 1920s and 30s, in the Los Angeles Jewish neighborhood of Boyle Heights.
Though raised together in Boyle Heights, where kosher delis and storefront signs in Yiddish lined the streets, Elaine and Barbara staked out very different personal territories. Elaine was thoughtful and studious, encouraged to dream of going to college, while Barbara was a bold rule-breaker whose hopes fastened on nearby Hollywood. In the fall of 1939, when the girls were eighteen, Barbaras recklessness took an alarming turn. Leaving only a cryptic note, she disappeared.
In an unforgettable voice layered with humor and insight, Elaine delves into the past. She recalls growig up with her spirited family: her luftmensch of a grandfather, a former tinsmith with tales from the Old Country; her papa, who preaches the American Dream even as it eludes him; her mercurial mother, whose secret grief colors her moods--and of course audacious Barbara and their younger sisters, Audrey and Harriet. As Elaine looks back on the momentous events of history and on the personal dramas of the Greenstein clan, she must finally face the truth of her own childhood, and that of the twin sister she once knew.
In The Tin Horse, Janice Steinberg exquisitely unfolds a rich multigenerational story about the intense, often fraught bonds between sisters, mothers, and daughters and the profound and surprising ways we are shaped by those we love. At its core, it is a book not only about the stories we tell but, more important, those we believe, especially the ones about our very selves.
Advance praise for The Tin Horse In the wry and witty voice of retiree Elaine Greenstein, author Janice Steinberg brings the bygone Jewish immigrant L.A. neighborhood of Boyle Heights to vibrant life. Part mystery, part sister story, part family history, The Tin Horse is a completely immersive reading experience. I closed the pages feeling as though Id lived another life.--Margaret Dilloway, author of How to Be an American Housewife Steinbergs novel introduced me to a dramatic piece of L.A.s history through the story of the Greenstein family, set in prewar Jewish Boyle Heights. Fascinating and meticulously rendered.--Janelle Brown, author of All We Ever Wanted Was Everything From the Hardcover edition.
A New York Times bestselling author takes readers inside the Ironman triathlon.
As he did so masterfully in his New York Times bestseller, The Gatekeepers, Jacques Steinberg creates a compelling portrait of people obsessed with reaching a life-defining goal. In this instance, the target is an Ironman triathlon-a 2.4-mile open-water swim followed by a 112-mile bike ride, then finally a 26-mile marathon run, all of which must be completed in no more than seventeen hours.
Steinberg focuses not on the professionals who live off the prize money and sponsorships but on a handful of triathletes who regard the sport as a hobby. Vividly capturing the grueling preparation, the suspense of completing each event of the triathlon, and the spectacular feats of human endurance, Steinberg plumbs the physical and emotional toll as well as the psychological payoff on the participants of the Ford Ironman Arizona 2009. His You Are an Ironman is both a riveting sports narrative and a fascinating, behind-the scenes study of what makes these athletes keep going..
A leading authority draws on new research to explain why the adolescent years are so developmentally crucial, and what we must do to raise happier, more successful kids.Adolescence now lasts longer than ever before. And as world-renowned expert on adolescent psychology Dr. Laurence Steinberg argues, this makes these years the key period in determining individuals life outcomes, demanding that we change the way we parent, educate, and understand young people.In Age of Opportunity, Steinberg leads readers through a host of new findings -- including groundbreaking original research -- that reveal what the new timetable of adolescence means for parenting 13-year-olds (who may look more mature than they really are) versus 20-somethings (who may not be floundering even when it looks like they are). He also explains how the plasticity of the adolescent brain, rivaling that of years 0 through 3, suggests new strategies for instilling self-control during the teenage years. Packed with useful knowledge, Age of Opportunity is a sweeping book in the tradition of Reviving Ophelia, and an essential guide for parents and educators of teenagers.
