Jacob Landau (1892-1952) was an Austrian-born American journalist who founded the Jewish Telegraphic Agency, the first Jewish news agency and wire service.
As a student at the University of Vienna, he was active in the Zionist movement.
After World War I, Landau moved the organization's offices to London.
In the early 1920s, Landau established New York City as the global headquarters of JTA.
The Palestine Bulletin would eventually become The Jerusalem Post.
