German rabbi; born about 1650 at Frankfort-on-the-Main; died at Heidelberg, September 19, 1728. At the time of his birth his father, Herz, was dayyan. Mattithiah officiated as rabbi at Bingen (Jacob Popper, "Responsa," ii., No. 8, Frankfort, 1742), and subsequently at Mannheim, where he taught in the college (see Klaus) founded by Lemle Moses. In 1708 he took part in the dedication of the Lemle Institute. Shortly afterward he was called to Heidelberg as rabbi to the congregation of that city, with jurisdiction over all the congregations in the Palatinate, which position he held until his death. The local memorial book praises his piety and learning.
