Is David Tepper Jewish?

Yes David Tepper is a Jew.

Wikipedia reports that: Tepper was raised in a Jewish family in the East End of Pittsburgh, Pennsylvania in the Stanton Heights neighborhood. He was the second of three children born to Harry, who worked as an accountant, and Roberta, who was an elementary school teacher who taught at public schools in the city... In 2006, Tepper donated $1 million to United Jewish Communities of MetroWest New Jersey toward their Israel Emergency Campaign.

Forbes (5/1/2016) ranked him #85 in the world's billionaires, saying:

"David Tepper, one of the most successful hedge fund managers ever, recently moved to Miami Beach from northern New Jersey, which was seen as a big tax blow to the Garden State. Tepper also moved his $18 billion hedge fund firm, Appaloosa Management, to Florida. Tepper's hedge fund performance in the years following the financial crisis has made him an investing legend. Tepper added to his legacy in 2015, a year in which many prominent hedge funds lost money, showing he could navigate though a volatile market period as deftly as a bullish one."

Here's a story from The New York Times about his move from NJ to Florida.
