レオ・シラード
Leó Szilárd, 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 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."
