Dr. P.A. Smithe was sent by the American Red Cross as a doctor and surgeon to work at a hospital in Vienna. He sailed to Europe in December 1915 and returned home in August 1916, according to his daughter, who donated his images to the National World War I Museum.

“Haile Selassie I (23 July 1892 – 27 August 1975), born Tafari Makonnen, was Ethiopia's regent from 1916 to 1930 and Emperor of Ethiopia from 1930 to 1974. The heir to a dynasty that traced its origins to the 13th century, and from there by tradition back to King Solomon and Queen Makeda, Empress of Axum, known in the Abrahamic tradition as the Queen of Sheba. Haile Selassie is a defining figure in both Ethiopian and African history.

Haile Selassie is revered as the returned Messiah of the Bible, God incarnate, among the Rastafari movement, the number of followers of which is estimated between 200,000 and 800,000. Begun in Jamaica in the 1930s, the Rastafari movement perceives Haile Selassie as a messianic figure who will lead a future golden age of eternal peace, righteousness, and prosperity. He himself remained an Ethiopian Orthodox Christian throughout his life”. – Wikipedia

It is amazing how much the humanity can change the face of the earth. Not only can it create huge craters, which look a lot like craters from meteors, they leave a big enough impact that it can be seen from space. Though this crater, caused by a massive explosion on 1 July 1916, looks large, being 90 feet deep and 300 feet across; it is nowhere big enough to be viewed for space. A common misconception is that the Great Wall of China can be seen from space. In reality, however, it is impossible. Not only is it of the same color as the earth near it, it is also not that wide. Deforestation, on the other hand, can be clearly seen from space. Also, at night, all the lights that the large cities produce are also very visible.

Members of French and German historical associations, who gather annually, together visited the battlefield of Verdun in France, the site of a bloody World War One battle that dragged on for around 10 months in 1916, claiming hundreds of thousands of lives and destroying many villages.

“The Gorch Fock is a tall ship of the German Navy (Deutsche Marine). She is the second ship of that name and a sister ship of the Gorch Fock built in 1933. Both ships are named in honor of the German writer Johann Kinau who wrote under the pseudonym "Gorch Fock" and died in the battle of Jutland/Skagerrak in 1916. The modern-day Gorch Fock was built in 1958 and has since then undertaken 146 cruises (as of October 2006), including one tour around the world in 1988. She is sometimes referred to (unofficially) as the Gorch Fock II to distinguish her from her older sister ship”. – Wikipedia

The ship returns to Germany following investigations in January while it was in port in Ushuia, Argentina, into allegations of attempted mutiny following the death of a female crew member. German Defense Minister at the time Karl-Theodor zu Guttenberg suspended Captain Norbert Schatz, and though investigators absolved Schatz of wrongdoing, critics charge the investigation was inadequate. The "Gorch Fock" is the German Navy's flagship training vessel. (Photo by Stuart Franklin/Getty Images)

The expertly colourised shots were brought to life by French bank technician, Frédéric Duriez (51). The images were provided by the Valois collection which belongs to the BDIC. “By colourising these photos, I reduce the time that separates us today from this conflict”, said Frédéric.

An undated archive picture shows a dog pulling a Belgian machine gun at an unknown location in northern France. A Viscount in the Armoured Cavalry Branch of the French Army left behind a collection of hundreds of glass plates taken during World War One (WWI) that have never before been published. The images, by an unknown photographer, show the daily life of soldiers in the trenches, destruction of towns and military leaders. The year 2014 marks the 100th anniversary of the start of WWI.
