Personal
I am Born on 7 March 1765 in Chalon-sur-Saone, France,I was a French inventor, known as the inventor of photography and a pioneer in the field.
when I was the age of thirty,i was a professor at the Oratorian college, a staff officer in the French army, and the Administrator of the district of Nice, France. In 1795, I resigned from his position as administrator of Nice to pursue research with my brother Claude. In August, 1807, the brothers invented an internal combustion engine, the pyréolophore, which ran on powdered fuel. Claude left for Paris, and later went up to London in an attempt to generate interest in the pyréolophore, while Joseph stayed behind. By 1813, i never stick one with one pursuit for too long, grew fascinated with popular art of lithography. He is noted for taking some of the earliest photographs, dating to the 1826.
Contribution to Photography
The history of photography dates back to the first-ever fixed picture was taken by me on a hot summer day in 1826. It took 8 long hours for i to produce a fixed photograph.i referred to these as Heliographs. Starting in 1829 he began collaborating on improved photographic processes with Louis Daguerre, and together they developed the physautotype, a process that used lavender oil.i received no credit for what was essentially his invention. my son eventually fought for and won his father's right to be credited for this invention.
Although by the late seventeenth century the camera obscura projected pictures onto paper and in the eighteenth century the German inventor J. H. Schulze observed that silver salts darkened when exposed to light, it was over a century later when i combined these two concepts to produce photography. From his workroom, which overlooked the courtyard of his family's estate,i made the first true attempt at photography in 1816. i used paper sensitized with silver chloride to capture a view from the camera obscura. This crude image faded away after a short time, and i could not find a means to render it permanent.
A short time later,I improved the same view by adding a card board diaphragm in front of the lens of the camera obscura.I also used nitric acid to "fix" the image briefly. I continued to capture the view of the estate's courtyard, but I improvements were in vain, because he still could not make images which would last. From 1817 to 1825, I experimented with producing negative and positive images etched on metal and glass with light-sensitive acids. Though the processes employed were totally different from the silver chloride process which eventually became photography, he was able to produce successful and permanent copies of engravings.
In 1826 first used a professionally made camera obscura. The camera was made by Charles and Vincent Chevalier, famed Parisian opticians. On a summer day in 1826, I used it to produce the first permanently fixed image from nature. The world's first photograph, a view of his courtyard on a pewter plate, had been exposed to sunlight for eight hours.
It was through the Chevalier brothers that I came to know Louis-Jacques-Mandé Daguerre. Daguerre, who had been trying to fix images on silver chloride paper, was told by the Chevaliers of I success. I wrote to the hesitant a several times before i began corresponding with me. I and Daguerre finally met in Paris in 1827.Im died four years later, leaving Daguerre to complete my work and take more than due credit for the same.
