Max Cohen

Max Cohen is a fictional American mathematician known for being the protagonist of the 1998 psychological thriller film Pi, written and directed by Darren Aronofsky. Portrayed by Sean Gullette, he is depicted as a reclusive and brilliant number theorist obsessed with discovering a 216-digit number within the mathematical constant pi that he believes will reveal universal patterns in nature, enable stock market prediction, and unlock the secrets of existence.

Cohen was born in the United States to Jewish parents.

Living in isolation in a cramped New York City apartment, Cohen relies on his homemade supercomputer to analyze vast datasets while grappling with chronic migraines, escalating paranoia, and social detachment that push him toward mental collapse. His relentless pursuit blurs the lines between scientific inquiry, mysticism, and madness, as encounters with religious groups and financial interests intensify his obsession and psychological unraveling. The character has become an emblematic figure in independent cinema, embodying themes of genius, chaos theory, and the perils of unchecked intellectual fixation.

The film Pi does not provide detailed information about Max Cohen's early life. As a fictional character, he is depicted solely as an adult mathematician living in isolation in New York City, with no backstory regarding his birth, childhood, or entry into any profession outside his mathematical pursuits. His chronic migraines are portrayed as a longstanding condition, but no specific origins or timeline from his youth are explored.
