View from the Window at Le Gras, first photograph Postcard

View from the Window at Le Gras (La cour du domaine du Gras) was the first successful permanent photograph, created by Nicéphore Niépce in 1826 at Saint-Loup-de-Varennes. Niépce captured the photo with a camera obscura focused onto a sheet of 20 × 25 cm oil-treated bitumen. As a result of the 8-hour exposure, sunlight illuminates the buildings on both sides. After an unsuccessful trip to Britain to attempt to interest the Royal Society in the process, Niépce gave the photo to the botanist Francis Bauer. It was last publicly exhibited in 1898, and was thereafter forgotten. Helmut Gernsheim brought the photo to prominence again in 1952 and the Eastman Kodak Company made a copy. In 1973, the University of Texas acquired the plate from Helmut Gernsheim. Today, the plate is on display at the Harry Ransom Humanities Research Centre. Life listed it among "100 Photographs that Changed the World".
