Paul Erdős, a man with no home and no job, was the most prolific mathematician who ever lived. At once enigmatic and accessible, eccentric and intelligent, Erdös defied the popular image of mathematics and inspired students and colleagues with his singular take on the world. This award-winning documentary was made between 1988 and 1991, capturing Erdős in various countries along with some of his numerous collaborators. It covers his unusual career and his personal life, and includes rarely seen footage of Erdös teaching and discussing his views.
