### My Mathematical Genealogy

I think that there is a rather interesing story connected to my mathematical genealogy.
Though he received his Ph.D. from Universidade de São Paulo in 1957 (the first Ph.D. ever granted by a
Brazilian university), my "great-grandfather," Paulo Ribenboim, did not formally have a Ph.D. advisor. "Grandad" (a.k.a. Andrew Granville) once told me that there is some
justification for calling us the "illegitimate line of Grothendieck." He also explained that there is some justification for listing Krull and Dieudonné as Paulo's
unofficial advisors as well. Click here for a entertaining article that Andrew wrote about Paulo's life. Unfortunately,
the pictures are missing.

At some point, the Mathematics Genealogy Project decided to list Jean Alexandre Eugène
Dieudonné, Wolfgang Krull, and Candido Lima da Silva Diaz as Paulo's advisors. Using David Alber's Geneagrapher,
I created a graph of my full "family tree." To see it, click here.
