2. Monolith, The Face of Half Dome, Yosemite National Park, California [1927]
Ansel Adams ( )
Adams used special filters to heighten the tonal contrast in his photographs. When discussing this image of Half Dom, he stated, “I had been able to realize a desired image: not the way the subject appeared in reality but how it felt to me and how it must appear in the finished print”.

3. Behind the Gare St. Lazare, Paris [1932]
Henri Cartier-Bresson ( )
Henri Cartier-Bresson (August 22, 1908 – August 3, 2004) was a French photographer considered to be the father of modern photojournalism, an early adopter of 35 mm format, and the master of candid photography. He helped develop the "street photography" or "real life reportage" style that has influenced generations of photographers that followed.
NOTE: I am not sure whether our use of this image would fall under “fair use” – requires looking further into Magnum photo’s copyright regulations.

5. Raising the Flag on Iwo Jima [1945]
Joe Rosenthal ( )
Raising the Flag on Iwo Jima is a historic photograph taken on February 23, 1945, by Joe Rosenthal. It depicts five United States Marines and a U.S. Navy corpsman raising the flag of the United States atop Mount Suribachi during the Battle of Iwo Jima in World War II.
The photograph was the only photograph to win the Pulitzer Prize for Photography in the same year as its publication, and came to be regarded in the United States as one of the most significant and recognizable images of the war, and possibly the most reproduced photograph of all time.[1]
Of the six men depicted in the picture, three (Franklin Sousley, Harlon Block, and Michael Strank) were killed during the battle; the three survivors (John Bradley, Rene Gagnon, and Ira Hayes) became celebrities upon their identification in the photo. The picture was later used by Felix de Weldon to sculpt the USMC War Memorial, located adjacent to Arlington National Cemetery just outside Washington, D.C.

6. Gandhi at His Spinning Wheel [1947]
Margaret Bourke-White ( )
Gandhi advocated the boycott of the machine made European clothing as it caused large scale unemployment in India. He took to making hand-made cloth called Khadi that was inexpensive and suitable for poor Indians. Most importantly, it showed Indians how to be self-reliant.  Gandhi worked on his spinning wheel (called Charakha) till his last days, claiming that he felt like he was eating stolen food if he did not work.

7. Salvador Dali A (Dali Atomicus) [1948]
Philippe Halsman ( )
In 1941, American photographer Philippe Halsman met the surrealist artist Salvador Dalí in New York City and they began to collaborate in the late 1940s. The 1948 work Dali Atomicus explores the idea of suspension, depicting three cats flying, water thrown from a bucket, an easel, a footstool and Salvador Dalí all seemingly suspended in mid-air. The title of the photograph is a reference to Dalí's work Leda Atomica (at that which can be seen in the right of the photograph behind the two cats.) Halsman reported that it took 28 attempts to be satisfied with the result. This is the unretouched version of the photograph that was published in LIFE magazine. In this version the wires suspending the easel and the painting, the hand of the assistant holding the chair and the prop holding up the footstool can still be seen. The frame on the easel is still empty.

9. Buzz Aldrin on the Moon [1969]
Neil Armstrong (1930- present)
On July 20, 1969, half a billion people watched as Neil Armstrong became the first person to set foot on the moon.
"That's one small step for man, one giant leap for mankind," he said, before imprinting his boot in the lunar dust. The televised images were relayed to Earth from a camera mounted on a leg of the Apollo 11 lunar module. Armstrong was joined on the moon by fellow crewmember Edwin "Buzz" Aldrin. Above them a third astronaut, Michael Collins, orbited in the mission's command module.
Neil Armstrong took this picture of Edwin Aldrin, showing a reflection in Aldrins visor of Armstrong and the Lunar Module. This is one of the only photographs showing Armstrong, who carried the camera, on the Moon. Aldrin later said, "My fault, perhaps, but we had never simulated this in training." (NASA photo ID AS )
