On June 12, 1964, a judge sentenced Nelson Mandela to life in prison. Exactly 49 years later, Mandela's grandson thanked people for their support Wednesday in the family's first statement since the former South African president was hospitalized on Saturday.

Back in 1964, Mandela was one of eight men accused of conspiracy and sabotage in the so-called Rivonia Trial, named after a suburb of Johannesburg where African National Congress leaders had hidden out in a farmhouse.

In an electrifying speech from the dock at the beginning of the defense case, Mandela addressed the court [click for audio]:

During my lifetime I have dedicated myself to this struggle of the African people. I have fought against white domination, and I have fought against black domination. I have cherished the ideal of a democratic and free society in which all persons live together in harmony and with equal opportunities. It is an ideal for which I hope to live, and to see realized. But my Lord, if it needs be, it is an ideal for which I am prepared to die.

Passing sentence, Justice de Wet compared the convicted men's crime to high treason but said that after careful consideration he had decided not to impose "the supreme penalty."

Outside the Palace of Justice in Pretoria, Winnie Mandela (right) waits for a glimpse of her husband, Nelson Mandela , as he and seven other men are carried off to jail in Black Marias on June 12, 1964. Mrs. Mandela waited in vain as the police van took another route and did not pass her.

Outside court, an anxious crowd had gathered. Aggrey Klaaste of South Africa's Post newspaper described the scene in his report the next day:

"Mrs. Winnie Mandela stepped out of the Palace of Justice with her head held high. A whisper ran through the crowd: “LIFE”. There was a sudden hush, an air of bewilderment — and then an almost audible sigh of relief."

Mandela and six of the other convicted men were transferred to a prison on Robben Island. It would be more than 25 years before he gained his freedom and was able to begin the task of building the democratic and free society he had dreamed of.

Darrell Hood, son of James Hood, enters Foster Auditorium for "Through the Doors" an event commemorating the 50th anniversary of the stand in the schoolhouse door, on the campus of the University of Alabama on June 11, 2013.

Fifty years ago, on June 11, 1963, Gov. George Wallace stood in the doorway of the Foster Auditorium, physically barring two African-American students, Vivian Malone and James Hood, from entering.

Wallace, who proclaimed the rallying cry in his inaugural address, "Segregation now, segregation tomorrow, segregation forever,"  was determined to keep a campaign promise to block integration at the university, reflecting a sentiment felt in much of the Deep South.

Deputy Attorney General Nicholas Katzenbach delivered a stern warning in front of media and hundreds of onlookers, asking the governor to "responsibly step aside" -- but he boldly refused. 

That afternoon, President Kennedy federalized the Alabama National Guard to force Wallace to stand down.  And the governor, flanked by state troopers, peacefully stepped aside. 

With that, Vivian Malone and James Hood walked through the doors, past Wallace, and into history.

The “Britain from Above” project preserves 95,000 of the oldest and most valuable photographic negatives in the Aerofilms collection, dating from 1919 to 1953. The negatives, which consist of both glass plates and early film negatives, are carefully conserved and scanned into digital format for public view.

According to its curators, English Heritage, this vast, historic collection was created by Aerofilms Ltd, the first commercial aerial photography company in Britain, set up by Frances Lewis Wills and Claude Grahame-White in 1919. The whole Aerofilms oblique collection contains more than 1.2 million negatives and thousands of photograph albums, held in Swindon, Edinburgh and Aberystwyth.

The 95,000 negatives illustrate the dramatically changing face of Britain in the first half of the 20th century. The project launched a new interactive website in June 2012.

An aerial view of the Wimbledon Championships in 1921, the final incarnation of the tournament at its original location in Worple Road, London. The following year new grounds were opened in Church Road, where the event continues to this day.

ITV News and msnbc.com's David R. Arnott report

The world's oldest tennis tournament enters its 136th year Monday as stars like Novak Djokovic, Rafael Nadal, Maria Sharapova and Serena Williams join battle at Wimbledon.

But when the picture above was taken, back in 1921, the names to look out for were Suzanne Lenglen of France and Bill Tilden of the U.S., both of whom would go on to retain the championship that year.

The photograph is among more than 15,000 images from one of the earliest and most significant collections of aerial photography of Britain that have been made available online for the first time.

The photos on the Britain from Above website, launched today, have gone through a painstaking process of conservation and cataloguing. See more of the images at ITV News.

Private Thomas W. Timberlake of Co. G, 2nd Virginia Infantry found this child's portrait on the battlefield of Port Republic, Virginia, between the bodies of a Confederate soldier and a Federal soldier.

Update, 11.00 a.m. ET — This post has been updated with all eight photographs in a larger size below.

The Museum of the Confederacy is appealing for the public's help in identifying the subjects of eight photographs picked up on the battlefields of the Civil War. 

The Associated Press reports that the images are being publicized in the hope that a descendant might recognize a facial resemblance or make a connection to the sites where they were found: 

Museum officials can only speculate on the children and adults, including soldiers, shown in the photographs. But whether they were sons and daughters, fathers and mothers, or siblings the prospect of identifying each grows dimmer with the passage of time.

Typically they were found by another soldier and handed down through generations. Ultimately an attic would be cleared or a trunk would be emptied and the photo would be given to the museum. Some have been in the museum's possession for 60 years or more.

If you can help identify the people in the photographs, get in touch with the museum or connect via Facebook or Twitter.

Norwegian explorer Roald Amundsen in the Antarctic in 1911.

The Associated Press reports:

Polar adventurers, scientists and the prime minister of Norway gathered at the bottom of the world Wednesday to mark the 100th anniversary of explorer Roald Amundsen becoming the first to reach the South Pole.

Under a crystal blue sky and temperatures of minus 40 F (minus 40 C), the group remembered the Norwegian explorer's achievement on the spot where he placed his flag on Dec. 14, 1911.

"We are here to celebrate one of the greatest feats in human history," Prime Minister Jens Stoltenberg said as he unveiled an ice sculpture of Amundsen.

Norwegian Prime Minister Jens Stoltenberg joins three polar adventurers heading to the South Pole on Dec, 14, 2011 to mark the 100th anniversary of Roald Amundsen's feat. Several expeditions skied across Antarctica to attend the ceremony though many were delayed and had to be flown the last stretch.

Stoltenberg also honored British explorer Robert Falcon Scott, who lost the race against Amundsen and arrived at the South Pole more than month later, only to find Amundsen's tent, a Norwegian flag and a letter from Amundsen. Scott and four companions died on the way out.

Amundsen and his team spent almost two months skiing across the frozen Ross Sea, climbing steep hills to the Antarctic plateau at about 9,800 feet (3,000 meters) and crossing vast ice fields to reach the pole. Read the full story.

Captain Robert Falcon Scott (L) with members of the British Antarctic Expedition, 1910-13, also known as Terra Nova at the South Pole next the tent of Norwegian explorer Roald Amundsen who beat Scott to the Pole by 33 days. Laying bare their dejection and determination, the story of Robert Scott's bid to become the first to reach the South Pole is being told by the men themselves, 100 years on from the ill-fated expedition.

From the Scott Polar Research Institute website:

"These rough notes: Capt. Scott's last expedition" (7th December – 5th May) puts on show papers from the British Antarctic Expedition 1910–13 held in the Polar Museum's archive collection, much of which has never been on public display before.

The exhibition tells the full story of the fateful Terra Nova expedition, not just through the famous journals and letters of Scott, Bowers, Evans, Oates and Wilson, who perished on their way back from the Pole, but through other members of the ship's crew and shore party.

The title of the exhibition comes directly from Captain Scott's message to the public written at the end of his journal, just prior to his death. Dated March 29, 1912, it reads: "Had we lived, I should have had a tale to tell of the hardihood, endurance, and courage of my companions which would have stirred the heart of every Englishman. These rough notes and our dead bodies must tell the tale, but surely, surely, a great rich country like ours will see that those who are dependent on us are properly provided for."

The University of California at Berkeley has a rich history of student protest, so it is fascinating to look through archive photos (bottom photo)  to see how much the demonstrations at Sproul Plaza today look like those 44 years ago. Back in 1967, it was opposition to the draft that brought out the protesters.

More than 5,000 anti-draft demonstrators jam the Sproul Hall Plaza at the University of California at Berkeley early today on Oct. 17, 1967 at the height of a teach-in. The demonstrators staged the teach in defiance of a court injunction. University officials and police took no action against the crowd which listened to speeches and songs and watched draft card burnings. University officials in implementing the injunction locked Pauley ballroom and the ASUG.

The wearing of poppies in honor of the war dead is common in Canada and the United Kingdom, though the practice was initiated by an American, Moina Michael, who was inspired by the 1915 poem 'In Flanders' Fields' by John McCrae. In the United States poppies are traditionally worn on Memorial Day, not Veterans Day, according to the Department of Veterans Affairs.

The Royal British Legion, a veterans' welfare charity, says that last year's poppy appeal raised over £36 million ($57 million) for British veterans and their families.

Earl Haig (1861 - 1928) watches the stamping of poppies by ex-servicemen during a visit to the British Legion poppy factory on October 22, 1926 in Richmond, Surrey, England. Haig, who commanded British forces during the Battle of the Somme, was a leading light in the spread of the poppy day appeal.

A woman views crosses in Scotland's first Field of Remembrance in Princes Street Gardens in Edinburgh on November 7, 2011. Volunteers helped plant approximately 11,000 remembrance crosses as a temporary memorial to mark the 90th anniversary of the Scottish Poppy Appeal.

The power of the poppy to fire emotions is illustrated by a couple of minor recent storms in the British press. The English and Welsh soccer teams' request to wear a poppy on their shirts this weekend was refused by Fifa, the sport's governing body, sparking outrage in some quarters. A compromise was later reached allowing the players to wear poppies on black armbands.

Meanwhile, others complain of 'poppy fascism' in which public figures are condemned if they do not wear the symbol. "Heaven be thanked that the soldiers of the Great War cannot return today to discover how their sacrifice has been turned into a fashion appendage," Robert Fisk writes in The Independent.
