Jack Steinberger is an experimentalist in high-energy physics who discovered a new type of neutrino with the physicists Leon Max Lederman and Melvin Schwartz . In a groundbreaking experiment, the three scientists were able to create the first laboratory-made beam of neutrinos. Their discovery led to the development of the so-called "standard theory" of matter. In recognition of these contributions, Steinberger and his co-investigators were awarded the 1988 Nobel Prize in physics.

Steinberger was born on May 25, 1921, in Bad Kissingen, Germany. His father was Ludwig Lazarus Steinberger, a cantor and leader of the local Jewish community, and his mother was Berta May Steinberger. Jack Steinberger and his brother left Germany in 1934 and immigrated to Chicago, Illinois. There, they lived with the family of Barnard Faroll, a grain broker. Later, Faroll was instrumental in bringing the rest of Steinberger's family to the United States.
