According to estimates from the Jewish People Policy Planning Institute’s study in 2007, there are 13.2 million Jews on Earth-less than 0.3 percent of the world’s population. Although small in number, the Jewish people boast some pretty remarkable statistics. According to jewfaq.org , 35 percent of former President Bill Clinton’s cabinet was Jewish, 23 percent of students in Ivy League schools are Jewish, and nearly 10 percent of the U.S. Senate is Jewish. Looking at these statistics, it is easy to wonder how Jews are so small in number and yet so influential in society.

Apart from some celebrities who may pop into your mind if you think of famous Jews, there are many others that you may not have known are Jewish.

Many famous scientists are Jewish: Albert Einstein, one of the most famous scientists of the 20th Century, was a Jew, as was Niels Bohr, who made outstanding contributions to atomic structure and quantum mechanics. Both scientists were awarded the Nobel Prize for Physics in 1921 and 1922, respectively. Scientist Jonas Salk was born to Russian-Jewish immigrants and went on to develop the first polio vaccine in 1955.

Musician George Gershwin was Jewish, as well as Bob Dylan and Julio Iglesias; fashion designers Calvin Klein and Ralph Lauren and entrepreneur Levi Strauss. In addition, many famous film directors and producers are Jewish; the list goes on and on.

Did you know the actor who plays Harry Potter was Jewish? Daniel Jacob Radcliffe was born in London in 1989 to a Jewish mother. Zac Efron, who starred in “High School Musical” and “Seventeen Again,” is Jewish by ethnicity. Drake Graham, a rapper who has collaborated with hip hop stars such as Lil’ Wayne, Kanye West, and Eminem, has an African-American father and a white Jewish mother. Graham had his bar mitzvah in 2002.

Jews are often victims to various stereotypes: some are considered good, some are considered bad. Jewish people are often characterized as intelligent, successful and good with money. Others argue that Jews are greedy, cheap and have big noses. These stereotypes are far from true.

Though there are disputes over who can be classified as a Jew, traditionally Judaism defines a Jewish person as anyone whose mother is Jewish or a person who has gone through the Orthodox process of converting to Judaism.

Although there are only 13.2 million, the Jewish population is incredibly diverse. Despite our small numbers, there will always be someone that you didn’t know was Jewish.
