I was reading about one of the prominent researcher in my field of study. Out of curiosity I read his PhD theses. It was supervised by yet another prominent scientist. I further went on to see his supervisor's PhD thesis and yes, it was a trend, it was supervised by yet another groundbreaking researcher. I stopped in a while, otherwise I think, I would have surely reached the pioneer of the field.
I went on for like 5-6 people down. I would like to know if this happens in your field of researchers also?
What can be the reason for this, are there any secrets passed on :P ?
