"The Martians" (Hungarian: "A marslakók") were a group of prominent scientists (mostly, but not exclusively, physicists and mathematicians) of Hungarian Jewish descent who emigrated from Europe to the United States in the early half of the 20th century.[1]
Leo Szilard, who jokingly suggested that Hungary was a front for aliens from Mars, used this term. In an answer to the question of why there is no evidence of intelligent life beyond Earth (called the Fermi paradox) despite the high probability of it existing, Szilárd responded: "They are already here among us – they just call themselves Hungarians." This account is featured in György Marx's book The Voice of the Martians.[2]
Marx was invoked but never defined (see the help page).
