Abstract
Although experiments with light-sensitive chemicals began in the early 19th century, it was not until the late 1830s that Louis Daguerre in France and Henry Fox Talbot in England found ways to indefinitely preserve an image on either glass or paper. Early emulsions required very long exposures, but by 1850 the daguerrotype process had been sufficiently improved for an image of the star Vega to be obtained using the 15-inch refractor at Harvard College Observatory.
