ANSWER: Photography

1947

In 1947, Edwin Land invented the first of what would be come a historic line of cameras. Called the "Polaroid Land Camera Model 95," this leather-bound beauty produced instant prints inside the camera in about one minute. This would become the technology that would distinguish Polaroid cameras from 1947 to 1983. Early versions required two rolls of film be spooled inside the camera -- positive and negative.
