Who is noted for their accuracy and detail in animal studies during the 1800s?

The emphasis on accuracy and detail in animal studies during the 1800s is closely associated with the work of Mary-Rosalie (Rosa) Bonheur. She was a renowned French painter known for her realistic and meticulously detailed representations of animals, particularly horses and cattle. Her approach combined precise observation of her subjects with a romantic interpretation, showcasing both the beauty of the animals and their natural environments. Bonheur's dedication to her craft included studying animals up close, even willing to dress as a man to gain access to slaughterhouses and farms for more authentic references.

In contrast, the other artists listed had different focuses and styles that did not revolve around the detailed study of animals. Pablo Picasso is best known for his role in developing Cubism and exploring abstraction rather than for realistic animal studies. Vincent van Gogh, while known for his vivid colors and emotional expression in landscapes and still lifes, did not specialize in detailed animal studies. Frida Kahlo is celebrated for her self-portraits and themes of identity and womanhood, with less emphasis on animal representation. Thus, Rosa Bonheur stands out in the context of animal studies in the 19th century for her accuracy and dedication to the subject matter.
