Christopher Carson (1809-1868), commonly called Kit Carson, was an American hunter, Indian agent, and soldier. He was one of the best-known and most competent guides available to explorers of the western United States.
The French inventing team of brothers Auguste Lumière (1862-1954) and Louis Lumière (1864-1948) was responsible for a number of practical improvements in photography and motion pictures. Their work on color photography resulted in the Autochrome process, which remained the preferred method of creating color prints until the 1930s. They
also applied their technological talents to the new idea of motion picture photography, creating the first projection system that allowed a film to be seen by more than one person at a time.
