Robert Frank with this small little book changed the course of photography. He changed the way people take photographs. He changed the way we look at photographs. He changed the definition of what was an acceptable or good photograph. The way Monet and Picasso changed how one could paint, Frank changed the way one could photograph.
How did he do this? He basically introduced the "icongraphic photograph" to the world. Take for example, his picture in the Americans of a political rally for Ike. It is of a man standing against a blank wall, playing the tuba. But the tuba's opening obscures his face, all you see is the big blank dark opening of the the tuba where his eyes and mouth are suppossed to be. And then right behind the tuba, almost coming out of it, a flag, an American flag, though shapeless, and formless and it snakes out of the picture. On the man's lapel is a big "For Ike" button. At the time, this was a radical photograph and statement about politics and the role of the individual in political life; remember this was 1957.
There are many many many other photographs like this throughout the Americans: St. Peter taking on City Hall. The American flag covering the faces of the people at a parade. The jukebox everywhere. The signs screaming "No Negroes Allowed" while on the next page is a photograph of an older black women holding in her arms, caring for, a young white baby. Frank clearly asking, screaming, why is it okay for them to care your for babies but not okay for them to use the same toilet as you?
It is a subtle but very powerful book. And once you see it, once you get it, you can never see a photograph the same way again.
He has influenced every photographer who has come after him.
Without Robert Frank there would be no Gary Winograd, Eugene Richards, Gilles Peres, William Klien, Bruce Davidson, Alex Webb, Salgado, Danny Lyon, James Nachtwey, Lauren Greenblatt, Ron Haviv, or Herb Ritts.
This book is the starting point for anyone interested in photography, or at least photography after 1958 when this book was first published.
