Charles Stuart Gregson (29 May 1817 - 31 January 1899) was an English entomological collector who worked as a ship painter.
He was considered a very industrious collector of specimens and named several species of moth.
Gregson was born in Lancaster and worked in Liverpool as a ship painter.
He kept an African eagle at home and served as a secretary to the Northern Entomological Society and the East Lancashire Natural History Society and maintained meeting minutes which revealed his lack of an education.
[1][2][3] He was known to be argumentative and was sometimes regarded with doubt as Edwin Brown remarked in a letter to Charles Darwin.
