the Jossa Arznei (the predecessor of RubiePharm) was founded by pharmacist Kurt Merz in the Brothers Grimm town Steinau. Steinau is located between the Vogelsberg Mountains, the Rhön region and the Spessart forest, directly at the motorway A 66.
After the sale of the enterprise in 1995, the RubiePharm Arzneimittel GmbH was founded by Rudolf Biegl, a former employee.
