Monique Martin, alias Gabrielle Vincent, was a writer and illustrator of children's books from Belgium. She was born in Brussels on 9 September 1928, and died there on 24 September 2000. Her nom de plume is derived from the first names of her grandparents, Gabrielle and Vincent.
She worked as a painter of water color before beginning a career in the 1980s as an illustrator with the series Ernest et Célestine, adapted for cinema in 2012.
The illustrations are adorable and it would be a very good read on a sick day. I felt we were missing some back story on Ernest and Celestine, but now I see it is 12th in a series. My mistake.
