Alfred Eisenstaedt's photograph of an American sailor kissing a woman in Times Square became a symbol of the excitement and joy at the end of World War II. The Life photographer didn't get their names, and several people have claimed to be the kissers over the years. A book released last year identifies the pair as George Mendonsa and Greta Zimmer Friedman. "Suddenly, I was grabbed by a sailor," Friedman said in 2005. "It wasn't that much of a kiss. It was more of a jubilant act that he didn't have to go back (to war)."

Following a crackdown that resulted in the deaths of hundreds of student demonstrators in Beijing, a lone Chinese protester steps in front of People's Liberation Army tanks in Tiananmen Squarein 1989. At least five photographers captured the event, which became a symbol of defiance in the face of oppression. Charlie Cole, working for Newsweek, won a World Press Photo Award for his version of the image. The identity and fate of the "Tank Man" remains unclear.
Joe Rosenthal's 1945 photograph of U.S. troops raising a flag in Iwo Jima during World War II remains one of the most widely reproduced images. It earned him a Pulitzer Prize, but he also faced suspicions that he staged the patriotic scene. While it was reported to be a genuine event, it was the second flag-raising of the day atop Mount Suribachi. The first flag, raised hours earlier, was deemed too small to be seen from the base of the mountain.
A hooded detainee in U.S. custody during the Iraq War stands on a box with electrical wires hooked up to his fingers. The image became a symbol of the Abu Ghraib prison abuse scandal after it was released, among others, in late April 2004. It did what a written report could not do, showing front-and-center what human rights groups had been saying for months: that prisoners were being abused at the hands of U.S. troops. The fallout was immediate, both overseas and at home.
During the Vietnam War, Eddie Adams photographed Gen. Nguyen Ngoc Loan, a South Vietnamese police chief, killing Viet Cong suspect Nguyen Van Lem on a Saigon street during the early stages of the Tet Offensive in 1968. Adams later regretted the impact of the Pulitzer Prize-winning image, apologizing to Gen. Nguyen and his family for the damage it did to the general's reputation. "I'm not saying what he did was right," Adams wrote in Time magazine, "but you have to put yourself in his position."
Richard Drew captured this image of a man falling from the World Trade Center in New York after the terror attacks on September 11, 2001. Its publication led to a public outcry from people who found the photograph insensitive. Drew sees it differently. On the 10th anniversary of the attacks, he said he considers the falling man an "unknown soldier" who he hopes "represents everyone who had that same fate that day." It's believed that upwards of 200 people fell or jumped to their deaths after the planes hit the towers.
In the immediate aftermath of the 2012 shooting at Sandy Hook Elementary School, local journalist Shannon Hicks witnessed police escorting children out of the school in Newtown, Connecticut.

The photograph made it onto the front pages of newspapers, magazines and websites around the world.

Robert Capa, co-founder of the Magnum Photos cooperative, became known for his 1936 photograph said to depict the death of a solider during the Spanish Civil War. Since the 1970s, doubt has been cast on the authenticity of the image. Many people suggest that it was staged. The International Center of Photography in New York and Magnum, among others, have defended the image. Either way, "The Falling Soldier" remains one of history's most famous war photographs.

"A cry like that will haunt anyone forever."

A widely published version of the image was manipulated by an anonymous editor to remove the fence post above Vecchio's head, sparking a major controversy.

Five decades after her death, Marilyn Monroe remains one of Hollywood's most adored sex symbols. Her sultry legacy is often traced back to the 1954 image of her posing over a New York City subway grate in character for the filming of "The Seven Year Itch." Monroe's then-husband, Joe DiMaggio, reportedly witnessed the spectacle and became enraged with jealousy. They divorced weeks later.
Dorothea Lange's photograph of a struggling mother with her children in 1936 became an icon of the Great Depression. Lange was traveling through California, taking photographs of migrant farm workers for the Resettlement Administration, when she came across Florence Owens Thompson. "I saw and approached the hungry and desperate mother, as if drawn by a magnet," Lange recalled in 1960. The image was retouched to remove the woman's thumb from the lower right corner.

Associated Press photographer Nick Ut photographed terrified children running from the site of a napalm attack during the Vietnam War in 1972. A South Vietnamese plane accidentally dropped napalm on its own troops and civilians. Nine-year-old Kim Phuc, center, ripped off her burning clothes while fleeing. The image communicated the horrors of the war and contributed to the growing anti-war sentiment in the U.S. After taking the photograph, Ut took the children to a hospital in Saigon.
President Bill Clinton hugs Monica Lewinsky at a 1996 fund-raiser in Washington. At the time their relationship wasn't public, so the image fell into obscurity. But when the news of their affair broke, photographer Dirck Halstead recognized Lewinsky and recovered the photo from his archives. It eventually ran on the cover of Time magazine, and the Lewinsky scandal led to Clinton's impeachment.

In 1937, Sam Shere photographed the Hindenburg disaster while on assignment in New Jersey. The crash killed 36 people and ended the era of passenger-carrying airships, which were once hailed as the future of flight. "I had two shots in my (camera) but I didn't even have time to get it up to my eye," Shere later said. "I literally shot from the hip -- it was over so fast there was nothing else to do."

Kevin Carter's 1993 photograph of a starving child in southern Sudan brought him worldwide attention -- and criticism. Carter said the girl reached a nearby feeding center after he drove the vulture off, but questions persisted about why he didn't carry her there himself.

He was struggling with depression and coping with the recent death of his close friend and colleague Ken Oosterbroek.
On Albert Einstein's 72nd birthday in 1951, photographer Arthur Sasse tried to get him to smile for the camera.

He signed one of the prints, which sold for more than $74,000 in 2009.
