Günther Porod (born 1919 in Faak am See near Villach, died 1984 in Graz) was an Austrian physicist. He is best known for his work on the small-angle X-ray scattering method, done in collaboration with his teacher Otto Kratky. In polymer physics, the worm-like chain model, introduced in a 1949 paper, is sometimes called the Kratky-Porod model.
In 1965 Porod was appointed as professor of experimental physics at the university of Graz.[1] In 1978, he was awarded the Erwin Schrödinger-Preis.
