He is Oded Goldreich, a communist professor of Computer Science and Math at the Weizmann Institute.  That is notable, because Weizmann ordinarily is not a well-known den for leftist moonbats.

There is an old stereotype of math professors who do complex advanced math but cannot add three plus three when it comes to the real world.

Goldreich is an open supporter of Israel's Stalinist communist party HADASH. He endorses it here on his personal web page: http://www.wisdom.weizmann.ac.il/~oded/politics.html . He opines at length about how awful capitalism is and how wonderful communism is here: http://www.wisdom.weizmann.ac.il/~oded/politicsJan03.html
He endorses the Arab version of history here: http://www.wisdom.weizmann.ac.il/~oded/PS/pi.pdf

He has signed all those anti-Israel petitions, including the ones promoting a "right of return" for Palestinians, meaning their right to destroy Israel (http://oznik.com/words/040712.html ), demands for internation involvement in order to curtail Israeli sovereignty (http://www.dasbistro.com/pipermail/clarkgreen/2003-April/001218.html ), called for granting terrorist Tali Fahima a Nobel Prize (http://jacobk9.tripod.com/id25.html ), and has endorsed calls for boycotts of Israeli schools (http://www.tomgrossmedia.com/mideastdispatches/archives/2005_05.html ) .
