Gideon Brecher

Gideon Brecher (January 12, 1797 – May 14, 1873), also known as Gedaliah ben Eliezer, was an Austrian physician and writer.

Gideon Brecher

Brecher was the uncle, by marriage, to Austrian bibliographer and Orientalist Moritz Steinschneider.

Brecher was born in Prossnitz, Moravia. He was the first Jew of Prossnitz to study medicine or any other professional field. Brecher received his Master of Surgery and Obstetrics in Budapest in 1824. He received his Medical Doctor's or MD degree the University of Erlangen in 1849. His thesis was Das Transcendentale, Magie und Magische Heilarten im Talmud, (Vienna, 1850).

Brecher's fame in Jewish literature rests principally on this work and upon his lucid commentary on the "Cuzari" of Judah ha-Levi, which appeared with the text in four parts (Prague, 1838–1840). Brecher's correspondence with Samuel David Luzzato about this commentary was also published.[1]

In addition to many contributions to scientific and literary periodicals and collections, and some important "Gutachten" (expert opinions) on social and religious questions submitted to him by imperial and local government officials, Brecher is the author of a monograph on circumcision, Die Beschneidung der Israeliten, etc., (Vienna, 1845), with an introduction by R. Hirsch Fassel of Prossnitz, and an appendix on Circumcision Among the Semitic Nations, by Moritz Steinschneider. Brecher also wrote Die Unsterblichkeitslehre des Israelitischen Volkes, Vienna, 1857, of which a French translation appeared in the same year by Isidore Cahen; and Eleh ha-Ketubim be-Shemot, a concordance of Biblical proper names, part of which was revised and published after his death by his son Adolph Brecher.

gollark: Modern password hashing functions are designed to be slow to run (and to be fastest on general-purpose computing hardware and not ASICs) to mitigate this sort of thing.
gollark: If you do *not* use that, then people can store a bunch of precalculated mappings from hashes to original passwords (rainbow tables, yes) and work out the original.
gollark: That's why salts are recommended (they're a bit of extra data you store along with the password and feed to the hash function when hashing it in the first place and comparing passwords with the hash).
gollark: The main attack on this is that you can, sometimes even using dedicated ASICs/FPGAs, run hashes *very fast* on a lot of possibilities and figure out what the original password was.
gollark: Yep!
