Asher Baer

Asher Baer (אשר בער; early 19th century, Seiny – 1897, Jerusalem) was a Russian Jewish mathematician and engraver.

He made many important discoveries in mathematics and especially in mechanics. He discovered a method by which the same force causes two different movements of two equal cog-wheels to dovetail with each other. His engravings were awarded a prize at the Königsberg Exhibition of 1858. The German press of that time devoted many articles to Baer's valuable inventions, and Ossip Rabbinovich and O. Wohl in the Russo-Jewish periodicals Razsvyet and Ha-Karmel spoke highly of his talent. In the later part of the 1860s Baer went to Jerusalem, whence he wrote correspondence for many years for Ha-Maggid and other Hebrew periodicals.
