David Moore Litt was born on September 17, 1986, in New York City to a Jewish family. Growing up on the Upper West Side of Manhattan, Litt was exposed from an early age to the vibrant cultural and intellectual environment that characterizes this part of New York. His upbringing in this diverse, progressive neighborhood would later influence his political perspectives and worldview.
The Upper West Side, known for its cultural institutions like Lincoln Center and the American Museum of Natural History, provided a rich educational backdrop for young David. This neighborhood, historically home to intellectuals, artists, and academics, fostered an environment where ideas and civic engagement were valued. Growing up in this setting likely contributed to Litt's early interest in politics, writing, and public service.
