My first encounter with boudoir photos from the early 20th century was a coincidence. My purchase of a Taxiphote stereoscope included 74 glass stereoviews from Jules Richard's Atrium collection. I started reading about the history of erotic photography during La Belle Époque and discovered the photographs of Jean Agélou.

Jean Agélou was a French photographer who is known for his erotic photographs. His French Postcards were very popular in the early 20th century, but he also created stereo photos.

I found 21 glass plate negatives with stereo images of the First World War. The slides provide an interesting insight into the mobilisation of the French army during the first weeks of the conflict.

Belgium was occupied by the German army during the First World War. Only a small part of southwest Flanders remained Belgian territory and was defended by the Allied armies. The city of Ypres was close to the frontline and was surrounded by German troops. The city remained in Allied hands during the war, but the Ypres Sailant became the scene of four major battles.

This stereoview shows a group of German prisoners of war guarded by French soldiers on horses. They're walking past a house with the text Gott strafe England! 1914/15. The photo was taken in the village of Bucy-le-Long in Northern France.

The vast majority of images from the First World War are black and white photos, but original images in color exist. They were made by using the autochrome process developed by the French Lumière brothers.

Erotic photography is almost as old as photography itself. Stereoscopic images of nude females were made by photographers like Auguste Belloc and Félix-Jacques Moulin in the 1850s. Erotic images became widely available in the beginning of the 20th century.
