Dennis Gabor — physicist and electrical engineer with roots in the Russian Empire
Dennis Gabor (born Günszberg Dénes, 5 June 1900, Budapest; died 9 February 1979, London) was a Hungarian-British electrical engineer and physicist. He studied and worked in Berlin, left Germany in 1933 and joined British Thomson-Houston in Rugby, where he invented holography in 1947 (sources give his arrival in England as 1933 or 1934). From 1949 to 1967 he was at Imperial College London. He was the sole recipient of the 1971 Nobel Prize in Physics.
Tracing the roots — Budapest (Kingdom of Hungary)
No documented link to the Russian Empire: Gabor was born in Budapest, then in the Kingdom of Hungary (Austria-Hungary), to Hungarian-Jewish parents Bernát Günszberg and Adél Jakobovits. Neither his Nobel autobiography nor English Wikipedia mentions Russian ancestry.
