Polaroid co-founder Edwin H. Land was born on May 7, 1909. In honor of his birthday, LIFE magazine has a tribute to his most popular invention, the Polaroid SX-70 Land Camera. Introduced in 1972, everyone wanted the "magic camera" that developed photos all by itself -no need to count the seconds and pull the film apart, as with earlier Polaroids. And the chemicals didn't leak. You could even watch the picture fade into view! Shown here is Edwin Land himself taking a picture with his SX-70. Link
