Kaplan or Caplan is also a surname common among Ashkenazi Jews, usually indicating descent from the priestly lineage (the kohanim), similar to the etymological origin of the common Hebrew surname Cohen. One of the earliest modern records of Kaplan as a family name is that of Abraham Kaplan in 1698. Distinguished bearers of the name include the Polish rabbi and philanthropist Nachum ben Usiel Kaplan (1811–1879), the Latvian-born Hebrew poet Seeb Wolf Kaplan (1826–1887) and the Russian-born Zionist workers' leader Eliezer Kaplan (1891–1952), the first minister of finance of the State of Israel.[6][7]
