Rainer "Rai" Weiss (/waɪs/; German: [vaɪs]; September 29, 1932 – August 25, 2025) was a German-born American physicist of partly Jewish descent (his father was Jewish). He was known for his works in gravitational physics and astrophysics.
He was a professor of physics emeritus at MIT. He was best known for inventing the laser interferometric technique, which is the basic operation of LIGO.
Weiss was Chair of the COBE Science Working Group.
In 2017, Weiss was awarded the Nobel Prize in Physics, along with Kip Thorne and Barry Barish, "for decisive contributions to the LIGO detector and the observation of gravitational waves".
Weiss died at a hospital in Cambridge, Massachusetts, on August 25, 2025, at the age of 92.
