Eugene Augustin Lauste, French-American engineer (d. 1935)

Eugène Augustin Lauste, born on January 17, 1857, in Montmartre, France, and passing away on June 27, 1935, in Montclair, New Jersey, was a pivotal French inventor whose groundbreaking work significantly shaped the technological development and early history of cinema. His prolific inventive mind was evident from a young age, as he had already secured an impressive 53 French patents by the age of 23, showcasing his early mastery of engineering and innovation.

In 1886, Lauste made the move to the United States, where his expertise quickly found a place within the burgeoning field of motion pictures. He began working as a key assistant to the French-born pioneer William Kennedy Laurie Dickson at the renowned Edison Laboratories. During this period, Lauste played a crucial role in the development of the Kinetoscope, a leading predecessor to the modern motion picture projector. The Kinetoscope was an innovative early device designed for individual viewing of films through a peephole, and while Thomas Edison is often credited with its invention, Lauste's contributions were fundamental to its realization. Lauste departed Edison's employ in 1892.

Beyond his contributions to cinema, Lauste’s inventive interests were remarkably diverse. He notably pursued an idea for a combustible gasoline engine in the 1890s. He successfully developed a working model, demonstrating his versatility, but ultimately abandoned the project due to concerns that such a noisy device would not achieve widespread practical adoption, a prescient observation for the era.

Lauste’s impact on early cinema continued through his collaboration with Major Woodville Latham. He engineered the Eidoloscope, an early film projection system, for Latham and was instrumental in the design of the revolutionary Latham loop. This mechanical innovation, later explicitly credited to Lauste by William Kennedy Laurie Dickson himself, was critical. The Latham loop provided slack in the film strip around the lens and intermittent movement mechanism, thereby relieving tension on the celluloid and preventing breakage. This ingenious solution allowed for the projection of much longer films than previously possible, a significant breakthrough for the nascent motion picture industry.

The Eidoloscope, benefiting directly from Lauste’s engineering and the Latham loop, was publicly demonstrated for members of the press on April 21, 1895. Its commercial debut to the paying public followed on May 20, 1895, at a store on lower Broadway. These early showings featured captivating films of the Griffo-Barnett prize fight, which had been filmed from the roof of Madison Square Garden on May 4. The ability to continuously shoot the entire boxing match on a single reel of film, a feat made possible by the Latham loop within the camera, was a remarkable achievement. That summer, Lauste held regular and popular displays of these motion pictures in a tent at Coney Island, entertaining growing crowds.

In 1896, Lauste joined the American Biograph Company, where he contributed his expertise for four years before relocating to Brixton, England. His most profound and forward-thinking contribution to cinema began to take shape here: the development of sound-on-film technology. In 1904, he prepared his first sound-on-film model, laying the groundwork for a truly integrated audiovisual experience. On August 11, 1906, Lauste, alongside Australian Robert R. Haines and Briton John S. Pletts, filed a British patent application. Their visionary application was granted as Patent No. 18057 in 1907. This patent described "a process for recording and reproducing simultaneously the movements or motions of persons or objects and the sounds produced by them," fundamentally defining a strip of 35 mm celluloid film that seamlessly combined both image frames and a corresponding sound strip. This was a monumental leap, as most other early attempts at synchronous sound relied on separate phonograph cylinders. In 1911, Lauste further demonstrated the viability of his invention by exhibiting a sound film in the United States, potentially marking the first-ever American public showing of a movie utilizing integrated sound-on-film technology. However, the widespread commercialization of his pioneering system was regrettably interrupted by the outbreak of World War I, which diverted resources and attention away from such innovations.

Lauste continued to be a respected figure in technological development well into his later years. From 1928 until his death, he served as a highly valued consultant for Bell Telephone Laboratories, a testament to his enduring relevance and expertise in communication and sound technology. Eugène Augustin Lauste was married to Melanie, with whom he had a son, Emile, and two stepsons, Clement and Harry E. LeRoy.

Frequently Asked Questions About Eugène Augustin Lauste

Who was Eugène Augustin Lauste?

Eugène Augustin Lauste was a highly influential French inventor, born in 1857, who made significant contributions to the early development of cinema technology, including the Kinetoscope, the Latham Loop, and pioneering sound-on-film systems.

What was Lauste's contribution to the Kinetoscope?

While often credited to Thomas Edison, Lauste worked as an assistant to William Kennedy Laurie Dickson at Edison Laboratories and was instrumental in the technical development of the Kinetoscope, an early peep-show device for individual film viewing, serving as a crucial predecessor to modern motion picture projectors.

What is the Latham Loop and why is it important?

The Latham Loop is a vital mechanical innovation in film projection and camera systems, engineered by Eugène Lauste for Major Woodville Latham. It creates a small loop of slack in the film strip, preventing tension and breakage as the film passes through the projector or camera. This innovation was critical because it allowed for the continuous shooting and projection of much longer films, revolutionizing early cinema's capabilities.

Did Eugène Lauste invent sound-on-film?

Eugène Lauste was a pioneering inventor in sound-on-film technology. He developed his first model in 1904 and, along with collaborators, secured a British patent in 1907 for a process that integrated image and sound directly onto a single strip of 35mm film. He even exhibited a sound film in the U.S. in 1911, possibly the first American showing of its kind, laying foundational groundwork for synchronized sound cinema.

What was the significance of Lauste's work at Bell Telephone Laboratories?

Lauste's role as a consultant for Bell Telephone Laboratories from 1928 until his death highlights his continued relevance and expertise in advanced communication and sound technologies, underscoring his lasting impact beyond the initial pioneering years of cinema.
