The Agronomist is a 2003 American documentary directed by Jonathan Demme, and starring Jean Dominique. The documentary follows the life of Dominique, who ran Haiti's first independent radio station, Radio Haiti-Inter, during multiple repressive regimes.
Haiti has had only one independent radio station.
Describing it as the first implies that more have followed or else it would just say the only independent station. The system was unable to factor in the idea of future stations being established.
