Christer Kiselman's mathematical ancestors

I defended my Ph.D. thesis at Stockholm University on December 3, 1966. My advisor there during the years 1961–1964 was

Lars Hörmander

I attended his lectures on partial differential equations in the fall of 1961 and the spring of 1962, and then his lectures on analytic functions of several complex variables in the fall of 1962 and the spring of 1963. Hörmander is now Professor Emeritus at Lund University. He defended his Ph.D. thesis at Lund University in 1955. His advisor was

Marcel Riesz (1886–1969)

He was professor at Lund University and got his Ph.D. in 1912 at the University of Budapest with

Lipót Fejér (1880–1959)

as advisor. Fejér got his Ph.D. at the University of Budapest in 1902. His advisor was

Karl Hermann Amandus Schwarz (1843–1921)

Schwarz received his Ph.D. in 1864. His advisor was

Karl Theodor Wilhelm Weierstrass (1815–1897)

Schwarz attended Weierstrass's lectures on Integral Calculus in 1861. Weierstrass was awarded an honorary doctorate by the University of Königsberg in 1854, so we cannot say he had a Ph.D. advisor. However, he studied mathematics for Gudermann in 1838–1840. In a more recent version of the Mathematics Genealogy Project, Gudermann is considered to be the advisor of Weierstrass, which makes it possible to go back to Gauss and Pfaff and even further...

André Martineau (1930–1972)

invited me to join him in Nice during the academic year 1967-68. He influenced me a lot. I have tried to sum up my memories on him and our year together in a note (in French).
