 Though both brothers worked on the collection, it was Auguste who actually wrote the works that were published.At the end of his life Eugène wanted to make the local Hotel de Bourgtheroulde in Rouen into a museum housing the collection, but this was not finalized before his death there where today a street bears his name.On the death of his brother Auguste Jean-Baptiste in 1902, who had been living in Rome, their collection of works of art was surprisingly bequeathed to the City of Paris rather than Rouen.
