Is Timothy Geithner Jewish? No.
No, Timothy Geithner, selected by Barack Obama to be secretary of the treasury, is not a Jew.
On 11/22/2008 I received an email from Geithner's father-in-law, Prof. Albert Sonnenfeld, confirming that, "Geithner (is) not Jewish, (he was) raised Episcopalian, but (is) hardly religious now.... "
The reference in Wikipedia that previously (up to 11/2008) said he is a Jew - was removed. See the discussion.
Geithner is now president of the Federal Reserve Bank of New York. He is the son of Mr. and Mrs. Peter F. Geithner of Larchmont, N.Y.
According to the Times, he is married to Carole M. Sonnenfeld and has two children. The Rev. Thomas Keehn, a United Church of Christ minister, officiated at his wedding in 1985.
