Aron Grünhut (1895-1974) was a businessman and Orthodox community activist who engaged in numerous humanitarian acts during the Holocaust. In the summer of 1939 he chartered two Danube steamships and transported about 1,350 Slovak Jews to Palestine. He survived the war in Bratislava, and then in hiding in Budapest, and in May 1945 returned to his native town. In 1948 he emigrated to Israel, where he was active in establishing the Pressburg Yeshiva and other activities related to preserving the memory of Bratislava’s Orthodox life. Grünhut later published his memoirs (Katastrophenzeit des slowakischen Judentums: Aufstieg und Niedergang der Juden von Pressburg, Tel Aviv, 1972). A memorial plaque was installed on his former house in 2015.
