The ancestor path above is only one path in the non-planar graph of academic ancestors that may be derived from

(This path was one of the the few paths which led back to the 14th century). Interestingly, this graph (starting at my node 0) had on 30 March 2010 a maximum of 31 layers, defined by subsequent advisorships, but only 112 people there defining the nodes of this graph. Co-advisorships were fairly rare in this graph. Older people in one path acted sometimes as co-adviors `further down' on the path, thus creating various kinds of `short cuts' between different layers in this graph, and also causing the non-planarity of this academic ancestor graph.

The chain from node 0 to node 11 (Kant) above does not have
any co-advisorship; thus this linear chain of the graph could be replaced by
any other ancestor chain leading to Kant.
By removing this chain, inclusive node
10 (Fichte), the remaining **academic ancestor graph of Immanuel Kant** had 20 layers and 101
nodes on 30 March 2010 on The
Mathematics Genealogy Project, and contains also people such as Justus Lipsius, Ehrenfried
Walter von Tschirnhaus, Erhard Weigel, Philipp Melanchthon, Rudolf Agricola, Desiderius
Erasmus, or Marin Mersenne.

It would be interesting to learn more about the intellectual network
created by such academic ancestorships -
how knowledge, ideas, opinions, or principles have been transported or reflected
within this graph, which
was created by somehow random relationships, depending on location, time, and
social circumstances, but also established based on individual interests.
