Emil Busch and the Evolution of Photographic Optics

Emil Busch Optische Anstalt was founded in 1845 by Emil Busch (1820-1888) in Rathenow, Germany. The company initially gained recognition by producing microscopes, telescopes, and other optical instruments. By the end of the 19th century, it had become one of the major optical manufacturers in Germany. With the rise of photography, Emil Busch began producing high-quality lenses for cameras. In 1865, the company developed the "Busch Rapid Aplanat" lens, which was considered revolutionary in the world of photography. This lens allowed for faster exposure times and sharper images, making it an important innovation in the field.

At the beginning of the 20th century, Emil Busch Optische Anstalt continued to produce more sophisticated and advanced photographic lenses. The company designed lenses in various formats and for different applications. It also focused on the production of optical devices, such as binoculars and telescopes, for both military and civilian purposes.

In 1927, the majority of the company's shares were acquired by Zeiss. Although the firm continued manufacturing cameras, it stopped producing lenses. After World War II, the company was closed down. In its place, the East German government established the firms VEB Rathenower Optische Werke and VEB Augenoptik "Hermann Duncker."

The card bears a total of 1400 German Marks worth of three stamps, reflecting the severe hyperinflation of the period. Two brown stamps, each worth 400 Marks, and one gray stamp worth 1000 Marks date back to the hyperinflation period of the Weimar Republic (1921–1923). Due to extreme inflation, even postal charges reached astronomical amounts. During this time, the German currency rapidly lost value, and daily necessities could cost trillions of Marks. Additionally, the stamps are postmarked in Rathenow, and the date, 1923, is clearly visible. The year 1923 is recognized as the peak of hyperinflation in Germany.

On the back of the card, the following statement is written: "Dear Ernst Bärtschi, Frutigen, as stated in your letter dated July 7, the transfer of 86.50 Swiss Francs to our bank account has not yet been confirmed by our bank. Therefore, we would like to inquire whether the payment has indeed been made and if there might have been an error on your part." This card reflects the financial hardships experienced in Germany during the hyperinflation period. In 1923, as the German Mark rapidly lost its value, international payments were often made in foreign currencies like the Swiss Franc, which were more stable.
