I must be getting old. Often as people get older they start to trace their family genealogy to learn "where they came from". I had been told since I was a child that my paternal great-great-grandfather was Samuel Shannon, one of the first Jewish settlers in Australia.
But, I had heard that scientists sometimes like to trace their academic lineage, where their Ph.D advisor is their parent, and the advisor of their advisor is their grandparent, and so on. Indeed there is a Mathematics Genealogy project which traces everyone back to Euler and Gauss...
So I got intrigued and checked out my own lineage. I was oblivious to this, beyond who my "great-grandfather" was. But, I did not know he had such a distinguished lineage. Finding the rest of my lineage was quite easy using Wikipedia because it listed the advisors of most of my "forebears". Here is the line:
