Irving Klaw was a man who liked to take pictures and make films. He lived a long time ago, in the 1930s and 1940s. And his pictures and films were a bit different from the ones you see today.
Irving Klaw made pictures and films of people in costumes, like superheroes and villains. And some of these costumes didn't have a lot of clothing on them. Sometimes, the people in these costumes were women, and they were tied up with ropes or chains. This might seem strange to you, but a lot of people liked these pictures and films at that time.
Some people even bought these pictures and films and put them in their own homes. But some other people didn't like them and thought they were bad. They said that Irving Klaw was making bad things and he shouldn't do it anymore.
So, Irving Klaw stopped making these pictures and films, and he started to do something else. He began to take pictures of normal things like families and babies, and he did that until he retired.
