Hi Jason, I checked with Kalevi's son just to be sure and yes, that is the same Kalevi.
He completed his PhD in 1966: https://www.genealogy.math.ndsu.nodak.edu/id.php?id=20539&fChrono=1 Then after a long career teaching Mathematics at the University of Helsinki he got involved with SymPy development as a retired Maths professor. Given his breadth of knowledge I had always assumed that his background was something like this although I never thought to go and look it up.
