Today, Hebrew is the official language of the Jewish people... but that almost wasn't the case.  In the early 20th century, religious Jews thought it was blasphemy to use their "holy language" for everyday conversation, and secular Jews from Europe preferred to speak the languages of their native countries.  Even Zionist leader Theodor Herzl envisioned a Jewish state with German as the official language. 

Throughout the early 20th century, Jewish diplomats such as Chaim Weizmann spent decades working to gain international support for a Jewish state.  At the same time, another man was in Palestine building that state from the ground up.  To his friends and colleagues, he was known simply as "the old man".  To the rest of the world, he's remembered as the founder and father of the State of Israel... David Ben-Gurion.
