The City of Light. For many, these four words instantly conjure late nineteenth-century Paris and the garish colors of Toulouse-Lautrec’s iconic posters. More recently, the Eiffel Tower’s nightly show of sparkling electric lights has come to exemplify our fantasies of Parisian nightlife. Though we reflect longingly on such scenes, in Illuminated Paris, Hollis Clayson shows that there’s more to these clichés than meets the eye. In this richly illustrated book, she traces the dramatic evolution of lighting in Paris and how artists responded to the shifting visual and cultural scenes that resulted from these technologies. While older gas lighting produced a haze of orange, new electric lighting was hardly an improvement: the glare of experimental arc lights—themselves dangerous—left figures looking pale and ghoulish. As Clayson shows, artists’ representations of these new colors and shapes reveal turn-of-the-century concerns about modernization as electric lighting came to represent the harsh glare of rapidly accelerating social change. At the same time, in part thanks to American artists visiting the city, these works of art also produced our enduring romantic view of Parisian glamour and its Belle Époque.

This guide replaces the 1984 publication entitled An Informational Guide for Roadway Lighting. It has been revised and brought up to date to reflect current practices in roadway lighting. The guide provides a general overview of lighting systems from the point of view of the transportation departments and recommends minimum levels of quality. The guide incorporates the illuminance and luminance design methods, but does not include the small target visibility (STV) method.

The Pulitzer Prize–winning historian explores history’s most daring and transformational intellectual movement, the European and American Enlightenment. In this engaging, provocative history, James MacGregor Burns illuminates the two-hundred-year conflagration of the Enlightenment, when audacious questions and astonishing ideas tore across Europe and the New World. They transformed thought, overturned governments, and inspired visionary political experiments. Fire and Light brings to life the revolutionary leaders who, armed with a new sense of human possibility, created the modern world. Burns traces the origins of a distinctive American Enlightenment to men like Benjamin Franklin, John Adams, Thomas Jefferson, and James Madison, and their early encounters with incendiary European ideas about liberty and equality. It was these thinker-activists who framed the United States as a grand and continuing experiment in Enlightenment principles. Today the same principles have taken on new urgency around the world: in the turmoil of the Arab world, in the former Soviet Union, and in China, as well as in the United States itself. What should a nation be? What should citizens expect from their government? Who should lead, and how can leadership be made both effective and accountable? What is happiness, and what can the state contribute to it? Burns’s exploration of the ideals and arguments that formed the bedrock of our modern world shines a new light on these ever-important questions. Praise for Fire and Light “With this profound and magnificent book, Burns takes us into the fire’s center. . . . Essential for deciphering the challenges of the world we will live in tomorrow.” —Michael Beschloss, New York Times–bestselling author of Presidential Courage “James MacGregor Burns is a national treasure, and Fire and Light is the elegiac capstone to a career devoted to understanding the seminal ideas that made America—for better and for worse—what it is.” —Joseph J. Ellis, Pulitzer Prize and National Book Award–winning author of Revolutionary Summer “[A] captivating tale. . . . Briskly and beautifully told. . . . Superb.” —Publishers Weekly
