David Maysles (1931-1987) was an American documentary filmmaker, a pioneer of Direct Cinema along with his brother Albert. In their creative partnership, David primarily handled sound recording and editing, while Albert was responsible for the cinematography. Their revolutionary approach consisted of observing and recording reality without commentary or direct interviews, allowing events to unfold naturally before the camera. Among their most acclaimed and influential works are *Salesman* (1969), a glimpse into the lives of door-to-door Bible salesmen; *Gimme Shelter* (1970), which documents the tragic Rolling Stones concert at Altamont; and *Grey Gardens* (1975), an intimate portrait of two eccentric relatives of Jacqueline Kennedy Onassis. The work of the Maysles brothers received numerous accolades and profoundly influenced the development of documentary filmmaking, with films like *Salesman* being selected for preservation in the United States National Film Registry for its cultural and historical significance.
