So I came across this funky website: The Mathematics Genealogy Project. I decided to take a look at my ancestry and thus traced my fathers back to Newton and Galilei!
(nb: graduated at Cambridge if not stated otherwise)

It is indeed a cool website. But you still need to complete you PhD in Math to be in there. More interestingly, everyone or almost everyone can be traced back to pretty famous people, which is quite understandable if you think about how education used to work back in the day. My current Algebra professor’s tree contains Cayley, Newton and Galilei. Nonetheless, interesting 🙂 Sadly, I won’t have such a tree.
Tod also links back to Cayley, Newton.
Batty and Tod are mathematical relatives!
(also, no mention of Stirzaker at all)
