The Luxor was founded in 1925 in Heidelberg by Heinrich Hebborn. His young age avoided him to go in the WWI and he started working at a paper mill until, around 1921, he meet in Heidelberg Rudolph Weber, a Kaweco shareholder, with which he began to collaborate becoming head of the Cologne branch. In 1925 he associated with a merchant of Jewish origins, Leo Boettigheimer (who later died in Auschwitz in 1943) and with a Kaweco agent, Heinrich Schlicksupp. The three together gave birth to "H. Hebborn & Co.".
Although the company official name was H. Hebborn & Co. it was universally known by the name of its main brand: Luxor; besides this, maintaining an inspiration to the themes of ancient Egypt, it also used as a sub-brand Sphinx. In 1938, the company moved production facilities in Cologne.
In the '40s, the company invented a telescopic piston filler with two concentric sections which allowed to have a much shorter mechanism, resulting in more space for the ink reservoir. The mechanism was mounted on a model called Teleskop, and it seems that it is the same one that was later adopted also by Montblanc for its flagship models of the series 130 and 140.
