Joseph Telushkin

Joseph Telushkin (born 1948) is an American Orthodox Jewish Rabbi. 
Telushkin went to the Soviet Union and repeatedly risked his own life to rescue Russian Jews from it and bring them to Israel. Telushkin co-wrote a book about the questions people ask about Judaism with his friend Dennis Prager. They also wrote a book about anti-Semitism and the reason for it. 
Telushkin also wrote a novel about a rabbi who has to solve a murder and a sequel to it. Telushkin also wrote a book called Jewish Literacy about everything that everyone should know about Judaism and another book called Biblical Literacy about everything that everyone should know about the Hebrew Bible. Telushkin also wrote a biography of a Rabbi Menachem Mendel Schneerson 
Telushkin made some videos for PragerU and was angry when "Newsweek" said that Dennis Prager had made fun of Anne Frank saying that all Prager had said was that he didn’t believe everyone was good at heart and that “Newsweek has hit a new low” in saying that that was making fun of her.
He has been on the "Newsweek" list of the 50 most influential rabbis in America since 1997.
