NIEDERLÄNDER, ABRAHAM BEN EPHRAIM (known also as Abraham Schreiber):
Austrian mathematician of the sixteenth century; scribe of R. Judah Löw ben Bezaleel (MaHaRaL) of Prague. He was the author of a mathematical work entitled "Berit Abraham" (Prague, 1609), which was based for the most part on Elijah Mizraḥi's works, although non-Jewish writings also were drawn upon. The book is divided into five sections and comprises a collection of problems under the title "Mozne Ẓedeḳ."
