A biography of H. E. van Rijgersma is given, with the genealogical register of his family. The zoological and historical literature, in which he was mentioned, is discussed. Van Rijgersma's illustrated manuscripts on botany (1868) and malacology (1875) of St. Martin, and his correspondence with malacologists, were discovered in the United States and studied. The recent mollusk fauna of St. Martin is summarized, consisting of 550 species, of which 136 are new to the fauna of that island.
