One of the New York Times Best True Crime of 2022 A “spellbinding, thriller-like” (Shelf Awareness) history about the invention of the motion picture and the mysterious, forgotten man behind it—detailing his life, work, disappearance, and legacy.The year is 1888, and Louis Le Prince is finally testing his “taker” or “receiver” device for his family on the front lawn. The device is meant to capture ten to twelve images per second on film, creating a reproduction of reality that can be replayed as many times as desired. In an otherwise separate and detached world, occurrences from one end of the globe could now be viewable with only a few days delay on the other side of the world. No human experience—from the most mundane to the most momentous—would need to be lost to history. In 1890, Le Prince was granted patents in four countries ahead of other inventors who were rushing to accomplish the same task. But just weeks before unveiling his invention to the world, he mysteriously disappeared and was never seen or heard from again. Three and half years later, Thomas Edison, Le Prince's rival, made the device public, claiming to have invented it himself. And the man who had dedicated his life to preserving memories was himself lost to history—until now. The Man Who Invented Motion Pictures pulls back the curtain and presents a “passionate, detailed defense of Louis Le Prince…unfurled with all the cliffhangers and red herrings of a scripted melodrama” (The New York Times Book Review). This “fascinating, informative, skillfully articulated narrative” (Kirkus Reviews, starred review) presents the never-before-told history of the motion picture and sheds light on the unsolved mystery of Le Prince's disappearance.

The true story of the French engineer and inventor who developed a mine detector for the US Army during WWII—and then went on to transform the oil industry. In March 1940, with Europe at war, French army lieutenant Henri-Georges Doll came to the U.S. embassy in Paris to give a deposition. Doll was an artillery commander, a graduate of France's grandes écoles of science, engineering, and service. He had been mobilized to the front at the start of the war, then quickly recalled to Paris to work on a secret device for detecting the deadly land mines being planted by the German army on a vast new scale. But Doll's deposition that day had nothing to do with the war. He had come to testify in a patent lawsuit pending in Houston, Texas. The case was Schlumberger Well Surveying Corporation v. Halliburton Oil Well Cementing Company: it marked one of the first great industrial battles for control of the technology of oil and gas exploration. When the German army marched into Paris three months later, Doll escaped to America, where he developed his new mine detector for the U.S. army, then settled in a small Connecticut town to become one of the most prolific inventors of the twentieth century. His sixth sense for applied science would help create the modern technology of seeing underground using electrical signals and sound waves—technology that would enable the explosive growth of oil production, and of Schlumberger, after the war. This biography tells his remarkable story.

Extrait :'Les aérostats (ballons) ont été inventés par les frères Montgolfier en 1783, et perfectionnés par le physicien Charles et le savant Nicolas Conté. Pilâtre de Rozier et le marquis d'Arlande furent les premiers qui osèrent, dès 1783, s'aventurer dans une nacelle suspendue à une montgolfière. Au nombre de nos contemporains qui depuis cinquante ans ont fait servir les aérostats à des expériences scientifiques, on doit citer : MM. Gay-Lussac et Arago.'À PROPOS DES ÉDITIONS LIGARAN : Les éditions LIGARAN proposent des versions numériques de grands classiques de la littérature ainsi que des livres rares, dans les domaines suivants : • Fiction : roman, poésie, théâtre, jeunesse, policier, libertin. • Non fiction : histoire, essais, biographies, pratiques.

In the latter half of the 19th century, Gustave Pierre Trouve, a modest but brilliant Parisian electrical engineer, conceived and patented some 75 inventions, including the endoscope, the electric car and the frontal headlamp. He also designed an electric boat--complete with outboard motor, headlight and horn--an electric rifle, an electric piano and luminous fountains, and developed wearable technology and ultraviolet light therapy. Unlike his famous contemporary Nikola Tesla, who worked for Thomas Edison and was patronized by George Westinghouse, Trouve never came to America. A confirmed bachelor disinterested in industrialization, he was gradually forgotten following his accidental death in 1902. This expanded edition of the 2012 French first-ever biography of Trouve details the fascinating life of the Chevalier of the Legion of Honor once dubbed'the French Edison.'
