The term Naïve art was coined in the nineteenth century (prior to that, images with a Naïve aspect may more accurately be categorized as folk art or simply as unprofessional works), and the first major proponent was probably the American Edward Hicks. Nevertheless, wasn't until the early 20th century that Naïve painting became fashionable. Henri Rousseau was the first Naïve painter to receive major critical acclaim, and he is still the only one who is considered a great master, but many others have earned respect in contemporary art.
