Bruno Touschek (3 February 1921 – 25 May 1978) was an Austrian physicist, a survivor of the Holocaust, and initiator of research on electron-positron colliders.

During this period, he worked at the Studiengesellschaft für Elektronengeräte, a company affiliated to Philips, where "drift tubes"—the forerunners of the klystron—were being developed at that time.

[1] After the war, he graduated from the University of Göttingen in 1946, where he came into contact with Werner Heisenberg and Carl Friedrich von Weizsäcker, and finished his diploma thesis.

This concept is at the base of all present-day very high energy particle accelerators, such as the Large Hadron Collider (LHC) at CERN.

The first electron-positron storage ring, called Anello Di Accumulazione (ADA), was constructed in Frascati under Touschek's supervision in the early sixties.

Even though ADA has been turned off long time ago, the laboratory is active and contributes work in the field of electron linear accelerators.
