Charles Rousseau is not a widely recognized name in the art world, and it is possible that you might be referring to a lesser-known or regional artist whose detailed historical records are not readily available. However, it is important to clarify that there might be a confusion with Henri Rousseau or Charles Rousseau Burney.
Henri Rousseau was a famous French post-impressionist painter in the Naïve or Primitive manner. He was born on May 21, 1844, in Laval, France, and died on September 2, 1910, in Paris, France. Known for his richly imagined jungle scenes, despite never having left France or seen a jungle, Rousseau's work has a dreamlike quality that has captivated audiences for over a century. Henri Rousseau was initially a tax collector and taught himself to paint. He exhibited at the Salon des Indépendants and was mocked by some for his amateurish quality of painting, but later he was celebrated for his unique style and is now considered a self-taught genius.
On the other hand, Charles Rousseau Burney (1726–1814) was not an artist but a music historian. He is well-known for his writings on music and musicians, including 'The Present State of Music in France and Italy' (1771) and 'The Present State of Music in Germany, the Netherlands, and United Provinces' (1773).
If you are looking for information on a specific Charles Rousseau who was an artist, additional context would be necessary to provide an accurate biography. There may also be a chance that records are scarce if the artist was not widely recognized or if their work did not have a significant impact on the art world. In such cases, biographical information would be limited to the artist's known works, any recorded exhibitions or sales, and potentially local or regional historical references.
