Who was a famous photographer for Life Magazine?

I'm not completely positive but I know Edward Steichen, who was a Luxembourgish American photographer, painter, and art gallery and museum curator, was featured on the cover of the January 10th, 1955 cover of 'Life' Magazine and also on the February 14th , 1955 edition as well. During this time Steichen was a very known Photography being that he was the man who some people say 'created' fashion photography. He's worked for both Vogue and Time magazine before becoming a WWII Photographer.
