Tibor Lantos was a Jewish businessman in Budapest, Hungary, during the interwar period and World War II era. He was the father of Thomas Peter 'Tom' Lantos (born February 1, 1928), who later became a U.S. Congressman known for his human rights advocacy. As a member of Budapest's Jewish community, Tibor Lantos worked in business, likely in banking or trade, contributing to the economic life of the city before the escalating persecutions under Nazi influence. His life reflected the broader experiences of Hungarian Jews facing increasing discrimination and restrictions in the 1930s and early 1940s. In 1944, following the German occupation of Hungary, Tibor Lantos and his wife, Ilona Lantos, were deported to Nazi concentration camps as part of the Holocaust. Both perished that year, victims of the systematic genocide that claimed the lives of approximately 565,000 Hungarian Jews. Their son Tom survived the war with the aid of Swedish diplomat Raoul Wallenberg and others who protected Jews in Budapest. Tibor Lantos' death underscores the devastating impact of the Holocaust on families like his, leaving a legacy remembered through his son's public service and commitment to commemorating such tragedies.
