10. 1923 – Testing the Modern Day Bulletproof Vest
In 1538, Filippo Negroli was commissioned to create a bulletproof vest. The earliest versions were made from iron or even silk. This image, however, was taken in Washington, D.C. in September of 1923, when the modern day bulletproof vest was first being tested. They used Kevlar. Now, this is being replaced by a material that has twice the strength of Kevlar, and is a fraction of the weight, this is called Graphene, but for almost a century, the pictured vest is what we used.
9. 1934 – Reichserntedankfest Rally
With roughly 700,000 in attendance, the Reichserntedankfest Rally, or the Thanksgiving Celebration of the Reich, took place in Buckeberg. The festival took place between 1933 and 1937 and was a celebration of German peasantry and farmers. The images are sometimes confused with the Nuremberg Rally which took place between 1923 and 1938.
