In 1931 Kodak bought the Nagel Camera Werks AG. Their goal was to make high-end cameras. They kept August Nagel on, leaving design and production in Stuttgart. He created the Kodak Retina series. The first cameras to use 35mm still film.
It was a huge success and the Retina series of cameras were used by many professional photographers for on-the-street candid shots. The quality was excellent.
One of the most famous was Ruth Orkinan. An award-winning photojournalist and filmmaker from the 1940s to 1970s. Some of her most important work was shot with these small cameras. She shot for Look and Life magazines and is credited with breaking into the heavily male dominated field of photojournalism.
Norman Rockwell also used the Retina to capture scenes. Rockwell is known to have always started with a photograph to create his paintings.
