Vladimir Jurko Glaser (April 21, 1924 - January 22, 1984) was a theoretical physicist working on quantum field theory and the canonization of the analytic S-matrix.
He was head of the Department of Theoretical Physics at the Ruđer Bošković Institute in Zagreb.
In 1955, he published one of the first monographs on Quantum Electrodynamics, Kovarijantna kvantna elektrodinamika (in Croatian).
In 1957 he left Croatia since he found permanent employment at the Department of Theoretical Physics of CERN, Geneva.
Together with Henri Epstein, he found a new approach to renormalization theory (causal perturbation theory), where ultraviolet divergences are avoided in the calculation of Feynman diagrams by using mathematically well-defined quantities only.
