TIME is debuting an unprecedented exploration of the 100 most influential photographs of all-time to commemorate the 175th anniversary of photography and the birth of photojournalism.
Among the photographs that are featured are Nat Fein's rear-angled composition of Babe Ruth at Yankee Stadium, which is the first sports photograph to ever win the Pulitzer Prize, and Neil Leifer's shot of Muhammad Ali reacting after his first round knockout of Sonny Liston in the 1965 World Heavyweight Title fight. The shot of Tommie Smith and John Carlos giving the Black Power salute at the 1968 Olympics is also highlighted in the project.
