The Tree was first displayed at the 30th Annual ASME International Mechanisms and Robotics Conference in Philadelphia September 11-13, 2006. On September 13th, at the Columbia University Remembrance of Prof. Freudenstein, the initial hardcopy of The Tree was presented to the Freudenstein family. At that time The Tree contained 5 generations of PhD's and more than 500 names. Today the Tree contains more than 750 names and 7 generations of PhD's descended from Prof. Freudenstein.
The Tree is available below as a pdf file. Even though the file size is small, The Tree is large! Download the pdf file and use your own pdf viewer (e.g. Adobe Acrobat/Reader DC, Foxit, Sumatra, etc.) to view the file. Try zooming in or searching for a name.
