G. Comba at Prescott. Thomas Jan Stieltjes (1856-1894) was a professor at the University of Groningen. He published widely in mathematical analysis and the theory of continued fractions. He defined the "Stieltjes integral", a generalization of the Riemann integral with wide applications to physics.
