This article is about the physicist; for the Swiss artist, see Ernst Alfred Stueckelberg

Ernst Carl Gerlach Stueckelberg ( February 1, 1905- September 4, 1984) was a Swiss mathematician and physicist.

In 1926 Stueckelberg got his Ph.D. at Munich under Arnold Sommerfeld. He qualified as a university lecturer together with Konrad Bleuler under supervison from Gregor Wentzel at the University of Zürich.

Independently from Hideki Yukawa, and arguably before him, he gave vector boson exchange as the theoretical explanation of the strong nuclear force in 1935.

In 1942 he proposed the interpretation of the positron as a negative energy electron traveling backward in time.

In 1943 he came up with a renormalization program to attack the problems of infinities in quantum electrodynamics (QED), but his paper was rejected by the Physical Review.

In 1976 he was awarded the Max Planck medal.
