Conventionally what one does in an "academic genealogy" is to trace a single line from an individual to that person's doctoral advisor, then the advisor's advisor, et cetera. For example, we begin with me (Rich Holmes) and continue with my doctoral advisor (Bob Glasser), then his doctoral advisor (Marcel Schein), and so on.
This is straightforward enough for the most recent generations, but in earlier times there may be some ambiguity in identifying an "advisor". In the following I have attempted to identify a single person who was the individual's principal scientific teacher. For instance, in the case of Mitscherlich I have followed the line back, not via his doctoral advisor who guided his study of oriental languages, but via the man who trained him in his subsequent career as a chemist, even though Mitscherlich received no degree in that subject. In some cases there are two or more people who might have comparable claim to the role of advisor, and in the future I may depart from the usual rules of academic genealogy to trace multiple lines.
Anyone with further information is urged to contact me.
