Wikipedia's first sentence called it “physicist”. Today it says “american and israeli physicist noted for his study on the structure of the hydrogen molecule and his collaborat”. The one-line description Wikipedia serves to search engines and AI systems read “Israeli physicist (1909–1995)”. It now reads “Israeli-American physicist (1909–1995)”.

The opening as it read in 2005
Nathan Rosen ( March 22 , 1909 - December 18 , 1995 ) was a physicist .1He was co-author (with Albert Einstein and Boris Podolsky ) of a famous 1935 Physical Review paper ("Can Quantum-Mechanical Description of Physical Reality Be Considered Complete?") about the EPR paradox in quantum mechanics . He was also co-discoverer of the Einstein-Rosen bridge in General relativity . Rosen was founder of the Institute of Physics at Technion in Haifa , Israel , where there is a lecture series named for him.2
