He was represented by the Howard Greenberg Gallery before his death and they continue to represent him. Margit Erb (who appeared in the video) works for the Gallery and is the Director of the Saul Leiter Foundation. She has been responsible for organizing Leiter's archive. She has also been instrumental in getting Leiter's monographs published, including "Early Color", "Early Black and White' and "In My Room". I assume it will be Howard Greenberg who will continue to profit from the sale of Leiter's work.
