Charles louis chevalier biography of william james
Barely out of his teens, the young optician began designing lenses that are believed to be the first to be used exclusively for photography. He soon began supplying photographic equipment to the most important European innovators of the era, including Joseph Nicephore Niepce de St. Victor, to whom he sold a camera obscura.
Mr. Chevalier introduced Niepce to Louis-Jacques-Mande Daguerre at his small Parisian shop, the Quai de l'Horloge. It quickly became a popular gathering place for photographic students and pioneers like Niepce and Daguerre who would exchange ideas about chemical combinations and discuss their latest experiments.
Biography of william shakespeare Charles-Louis Chevalier () was the son of Vincent Chevalier (). They were in business together when they introduced an achromatic objective in to reduce chromatic aberrations in microscope optics. The Chevaliers also discovered how to control spherical aberrations.
Mr. Chevalier's addition of an amplifier to the solar microscope in improved the instrument's quality tremendously. Also in , a stranger entered Mr. Chevalier's shop and boldly announced he had succeeded in capturing a camera image onto paper. As the optician later recalled, the young man produced the sheet of paper of a camera image of a Parisian landscape.
An astounded Mr. Chevalier wanted to know how this process was achieved and was handed a bottle of liquid and some instructions. According to legend, the stranger exited the shop without giving his name, never to be seen or heard from again. Mr. Chevalier attempted to reproduce the technique following the instructions on the liquid bottle, but fell short likely due to improper paper preparation.
However, his brief encounter with the young man excited the optician to the unlimited possibilities of photography.
In , Mr. Chevalier began selling the Giroux daguerreotype camera fitted with the achromatic lens he originally designed for microscopes, believed to be the first photographic camera offered for public consumption. He also experimented with the double objective process he first patented in , but his doublets were used solely as an object glass for telescopes until they apparently were first applied to photography in by someone other than Charles-Louis Chevalier.
However, also in , Mr. Chevalier introduced a portable daguerreotype folding camera known as the Photographe. The following year, he began selling lenses, equipment, and sample daguerreotypes to prominent English photographer Henry Fox Talbot. He took top prize at Paris' Societe d'Encouragement for his photographic lenses over Voigtlander's Petzval portrait lenses.
Unfortunately, the Petzval lenses soon overtook Chevalier's lenses in popularity and sales, much to his considerable frustration.
