Biography

Brian Josephson is recognized among Jewish contributors to Science & Medicine — Physicist; predicted the Josephson effect in superconductors, Nobel Prize 1973

How & why

Josephson, born into a Welsh Jewish family in Cardiff, made his landmark discovery as a 22-year-old graduate student at Cambridge. Working through the quantum theory of superconductivity, he predicted that a supercurrent could tunnel across a thin insulating barrier between two superconductors — the Josephson effect. Confirmed experimentally soon after and honored with the 1973 Nobel Prize in Physics, the effect underpins SQUID magnetometers, ultra-precise voltage standards and superconducting qubits.
