During an internet search we came across a dissertation by Dr. Martin Vialon on Dr. Freya Hobohm. With his kind permission we have uploaded it onto our website.
This dissertation was submitted to the Philipps-University in Marburg in 1998. It can also be retrieved from the server of the Marburg University library, which also gives the full bibliographical references.
We are presenting this dissertation in two versions - as an HTML file for online reading, and as a PDF file for downloading and printing. For the latter, you will need the Acrobat Reader software which can be downloaded for free from the Adobe website, by clicking the Get Acrobat Reader button.

Unfortunately this dissertation is only available in German.
Enjoy reading this very interesting dissertation which gives plenty of food for thought.
