Birkenstock

Early years

The history of the Birkenstock "shoemaking dynasty" can be traced back to the first documented mention of Johannes Birkenstock (1749–1812), registered on 25 March 1774, as a "vassal and shoemaker" in local church archives in the small Hessian village of Langen-Bergheim. Since that time, there have been five generations of master shoemakers or part-time shoemakers, several lines of the Birkenstock family working in the shoemaking trade and finally three generations of shoe manufacturers. In 1774, Johannes Birkenstock had already trained as a shoemaker and settled in the small Hessian town of Langen-Bergheim; he became a master shoemaker shortly afterwards. After his younger brother Johann Adam Birkenstock (born 1754) died in 1790, his son Johannes (1790–1866) grew up with his uncle Johannes and also became a master shoemaker.

His grandson, Konrad Birkenstock (1873–1950), left the Wetterau after also training as a shoemaker and opened an orthopaedic shoemaker's workshop in Frankfurt am Main in 1896 and founded Konrad Birkenstock GmbH a year later. Konrad Birkenstock developed the first contoured insole for use by shoemakers in the production of custom footwear. His success in orthopaedic circles with his insoles and health shoes and the satisfaction of his customers did not lead to financial success. The inventor Konrad Birkenstock concentrated too much on the further development of his material mix in order to further develop healthy walking. When he himself was called to the orthopaedic workshop of the Friedrichsheiner Klinik in Frankfurt am Main – and therefore did not have to do military service – he relocated his business activities. In 1915, Konrad Birkenstock acquired a house in Friedberg (Hesse), where the production of insoles now took place. In 1925 Konrad Birkenstock acquired the Derfelt soap factory in Friedberg, Hesse, thereby expanding production.

As a master orthopaedic shoemaker, Konrad Birkenstock invented a fully plastic last as early as 1897 and a fully plastic flexible insole in 1902. Shoes made on this last and with this insole were called "health footwear" by Konrad Birkenstock. With this invention, Konrad Birkenstock had followed the ideas of the shoe reform, which, in keeping with the times, rethought the human body. His flexible insoles, developed along the same lines for healing purposes, differed from the rigid insoles made of metal that were common at the time. In 1914, Konrad Birkenstock's insoles were recognized as orthopaedic remedies for the first time. He gave two of these insoles the name "footbed". In 1925, Konrad Birkenstock was able to register the "Fussbett" trademark. In the 1920s, Birkenstock insoles were already being supplied to Austria, France, Denmark, Czechoslovakia, Italy, Luxembourg, Belgium, Norway, the Netherlands, Sweden and Switzerland.

Konrad Birkenstock had three sons and one daughter. Over the course of time, they all became involved in the manufacture of orthopaedic insoles, in different companies and in different family constellations. His eldest son Carl (born in 1900) followed in Konrad Birkenstock's footsteps during the First World War. He visited specialist shoe stores and shoemakers and explained to them the use and effect of the "Birkenstock system", as the combination of a fully plastic last and flexible footbed was soon called. Carl continued to develop his father's deposits, was active with his own business in Vienna from 1923 to 1926 and founded Geb. Birkenstock GmbH in Steinhude am Meer together with his brothers Heinrich and Konrad Jr. in 1929. From 1939, Carl Birkenstock continued to run the company, which at that time had 13 employees, alone without his brothers. Carl Birkenstock took the idea of foot health even further than his father and limited sales of his insoles to specialist retailers and shoemakers who had successfully completed his training course. Although he managed to get over 6,000 people to attend this course, this approach still limited his sales options in the long term. However, it was important to him that his flexible insoles were fitted correctly in order to achieve the effect of a foot-health-preserving insole. He wanted to avoid incorrect use at all costs.

Carl Birkenstock joined the Nazi Party (NSDAP) in 1940. Carl continued to sell insoles at least until 1943, the year he unsuccessfully tried to enlist in the Sturmabteilung. Birkenstock attempted to gain government contracts in the early '30s, pitching his products to Hitler Youth, testing his insoles on SS members, and selling to individual soldiers. Six of the owners of Gebr. Birkenstock GmbH in Steinhude im Meer were drafted into the Wehrmacht. However, despite these ties, Birkenstock had no supply contracts between Birkenstock and the Wehrmacht, the Nazi Party or its organizations, or links to the Schuhprüfstrecke of the Sachsenhausen concentration camp, nor is there any record of the firm or company "Aryanizing" Jewish property.
