The  company that produced the Luxor fountain pens was founded in 1925 by Heinrich Hebbron, who (prior to the Luxor experience) was associated with the famous Kaweco company. So, in 1925 he associated with another two fellows, Leo Boettigheimer  and Heinrich Schlicksupp, incorporating "H. Hebborn & Co." in Heidelberg, Germany. Later on, the company and its business moved to the city of Cologne (Köln).

Although the company was always officially known as Hebborn & Co, it was better known as "Luxor" due to its well-known fountain pen model with that name. Fact check: the inspiration of some of their pens was drawn from the themes of ancient Egypt; at one time, there was a sub-brand called "Sphinx".

In 1935, the company patented a new and improved piston filler mechanism, which they called "Teleskop". It was a very ingenious mechanism, allowing the pen to be loaded with a much larger quantity of ink, in the same space as used by a regular piston filler. It is presumed (alleged?) that this mechanism stands at the origin of the famed Montblanc pistons (series 130-140), later on. Luxor was known for producing the models Visible and Grandvisible, among other.

During the 70's. the company ceased to exist, when it was purchased by the German branch of Parker. 

A very interesting fountain pens museum can be visited in Heidelberg Germany, you can check it here: http://www.newpentrace.net/Neureiter%20article.html. Not just about Luxor pens, but regarding all the German fountain pen manufacturers in the area of Heidelberg, or so I understood from the article quoted.

Not far from what our own Flaro factory should've done years ago. Instead, we now know next to nothing about the manufacturing of Romania pens. Just great...
