German Hebrew scholar; lived at Posen in the sixteenth century. Nepi-Ghirondi's "Toledot Gedole Yisrael" (p. 203) mentions a Joseph Heilbronn who died at Padua in 1622, but who can not be identified with Joseph ben Elhanan. Heilbronn wrote: "Em ha-Yeled," an elementary Hebrew grammar for the use of children, with conjugation tables and explanations in German (Prague, 1597); "Me'irat 'Enayim," the 613 commandments arranged according to Maimonides (Prague, n.d.); "Ḳol ha-Ḳore," a short Hebrew grammar for use in schools (Cracow, n.d.).
