Theodor Frobenius was born in a small town Weikersheim in Bavaria Germany in 1885. His father was a wine keeper - wine cellar manager. When Theodor was thirteen years old he became an apprentice at August Laukhuff organbuilder (they still work actively). The Laukhuff organbuilder factory was located just across the street from his home. The apprenticeship was four years, and after a further year Theodor left  Weikhersheim to travel around and work in other workshops. Back then it was common for young journeymen to travel around in Europe work in different places in order to acquire a comprehensive knowledge and skills. For Theodor it was for three and a half years in various German workshops. Along the way he met a Danish organ builder companion A.C. Zachariassen, who later take over an organ builder workshop in Aarhus (Denmark) and Theodor traveled to Denmark to work with him. The plan was that he stays for a year or two, but it went quite different. During the renovation of the organ in Viborg Cathedral, he met his future wife, and the plan to travel back to Germany has vanished.

Establishing of the company

In 1909 Theodor Frobenius took the management of a new organbuilder workshop as the Copenhagen piano manufacturer Chr. Winther expanded his business. The organ building was housed in an old dismantled mill in Nørrebro, Copenhagen. The first task was the building of a six-voice organ for Harboøre Kirke. This work had been started by an accredited organ builder but never finished, so in fact, it was a whole new instrument. Winther and Frobenius continued to work with two smaller organs, and then they got a contract for the construction of two larger organs (17 and 22 voices) in Godthåbskirken and Gustafskyrken (the Swedish church in Copenhagen). This way, a door was opened for new and larger tasks, including organs to Aalborg Vor Frue Kirke and Budolfi Kirke (Aalborg Cathedral). The organs were all personal victories for Theodor and within a few years, the name Frobenius was associated with high quality. In 1914, Theodor was taken up as a partner in the firm, which now was named Chr. Winther & Th. Frobenius Church Organ Factory. The old mill become too small, and the growing company was therefore moved to larger workshops in Classensgade, Copenhagen. Already in 1917, it was clear that it was natural to separate the organ production from the piano company. The administrative cooperation was terminated, and Theodor Frobenius became the sole owner. In 1926 the company was moved to Kgs. Lyngby where it resided for the next 92 years and  made more than 900 new organs. Since 2018 Frobenius Orgelbyggeri has resided in our new, modern workshop in Birkerød outside Copenhagen.

The Frobenius Family
Theodore Frobenius was happy about that all three of his children chose to spend their working lives as organ builders. Under the leadership of Walther and Erik the company was converted into a public limited company and was named Th. Frobenius & Sønner (Frobenius & Sons) A/S. Erik was responsible for the voicing and the tonal quality of the instruments while Rita had over a lifetime work with the financial background of the production and services. The generational change in the company did not mean for Theodor leave his profession, even in his very old age he stood faithfully every day and often late into the evening in the workshop where he prepared the pipes for the final voicing. With extreme care he made the pipes ready for the final tonal adjustment which took place in the church.

Theodor Frobenius died in 1972. Rita Schepeler died in 2001, Erik Frobenius passed away in 2002, and
Walther Frobenius followed him in 2007.

Frobenius Foundation / Leadership
Where succession after Theodor had straightforward, there was no immediate possibility for a third Frobenius generation to take over the company and family tradition. Rita and Erik therefore created a foundation 'Frobeniusfonden' which, took over the shares, and ownership of the company. Organ builder Henning Jensen (former founder and owner of Fyns Orgelbyggeri) became the CEO of Frobenius. Since 2017 organ builder Eskild Momme leads the company as CEO.

Jensen & Thomsen
In 1996 Frobenius took over the organ builders Jensen & Thomsen, which company was founded by two former employees of Frobenius, Knud Jensen and Richard Thomsen. The idea was to complete the work that this organ building was in order, but it turned out that even after the acquisition were many clients who loved and wanted Jensen & Thomsen organs. So the production continued so in the next 12 years the company built a number of new instruments until 2007 when the brand was completely discontinued.

Organ Builder Carsten Lund
Frobenius took over the company in 2010. Like in the case of Jensen & Thomsen, there was still demand for organs from Carsten Lund. So the production continued, and in the following 7 years, 6 new
Carsten Lund instruments were delivered in Denmark and Norway. The last Carsten Lund organ was delivered to Jevnaker in Norway in 2017.

Moving of the Company
After 92 years the company moved the production and headquarters from Kongens Lyngby. The new place is not far away, just 14 km (8.7 miles) more to the north, in the industrial area of the city of Birkerød. The production and maintenance of the organs continues according to our traditions, as our hi-quality standards require.
