Imagine a world without photography, one could only imagine.

I have yet to see a fine photograph which is not a good document.

Today we are confronted with reality on the vastest scale mankind has known and this puts a greater responsibility on the photographer.

I wanted to combine science and photography in a sensible, unemotional way. Some people’s ideas of scientific photography is just arty design, something pretty. That was not the idea. The idea was to interpret science sensibly, with good proportion, good balance and good lighting, so we could understand it.

I think the important decision for a photographer is to choose a subject that intensely interests him or her.

You scientists are the worst photographers in the world and you need the best photographers in the world and I'm the one to do it.

I'm not a nice girl; I'm a photographer. (On being told by a Federal Art Project official, after she photographed the Bowery, that a nice girl should not go into such neighborhoods )
