Vladimir Jurko Glaser (21 April 1924 – 22 January 1984) was a Croatian theoretical physicist working on quantum field theory and the canonization of the analytic S-matrix.
[1] His paternal aunt Eleonora (Lola) was married to the famous neurologist Constantin von Economo.
Being a part of Heisenberg's group at Göttingen he later worked with many famous physicists such as Harry Lehmann, Wolfhart Zimmermann (on extensions of LSZ formalism) and Walter Thirring.
[7] With French physicists Jacques Bros and Henri Epstein he worked on setting up analyticity properties required for the use of dispersion relations in high energy collisions.
[5] Epstein, Glaser and Arthur Jaffe proved that (Wightman) quantum fields can necessarily have negative energy density values.
