I first became acquainted with Harry Callahan when I was in the Friends of Photography back in the 80’s. I received their quarterly publication called Untitled. Untitled focused on one photographer for each edition. Untitled 36 was called Eleanor. That issue’s pictures were of Harry Callahan’s wife, Eleanor. Callahan’s photographic style was nothing like anything I had ever seen. Maybe that’s why I latched onto it. That and his obvious love of his wife, Eleanor, really pulled me in. That book is still one of those that I keep in my office for inspiration.
Here is a YouTube video of Harry Callahan showing some of his work.
