An academic, or scientific, genealogy, organises a family tree of scientists and scholars according to mentoring relationships, often in the form of dissertation supervision or postdoc supervision relationships.
My academic tree begins with my PhD supervisor Andrew White and from there we see my lineage back to notable and eminent scientists such as Charles Townes, John Wheeler, Niels Bohr, Ernest Rutherford, James Clerk Maxwell, Hermann Von Helmholtz of relatively modern times. However, one can go all the way back! Importantly for me, I am direct academic descendant of one of my personal heroes (see quote on welcome page), Johann Wolfgang von Goethe, via 15 steps. Some other notable cases more related to my own scientific pursuits are Isaac Newton (directly 19 steps), Galilei Galileo (directly 21 steps), Nicolaus Copernicus (directly 23 steps) and much much further.
We are all connected in some way or another.
If I have seen further, it is by standing on the shoulders of giants.
