In 1877, both her entries were rejected, and for the first time in seven years she had no works in the Salon. At this low point in her career she was invited by Edgar Degas to show her works with the Impressionists, a group that had begun their own series of independent exhibitions in 1874 with much attendant notoriety. The Impressionists (also known as the "Independents" or "Intransigents") had no formal manifesto and varied considerably in subject matter and technique. They tended to prefer plein air painting and the application of vibrant color in separate strokes with little pre-mixing, which allows the eye to merge the results in an "impressionistic" manner. The Impressionists had been receiving the wrath of the critics for several years. Henry Bacon, a friend of the Cassatts, thought that the Impressionists were so radical that they were "afflicted with some hitherto unknown disease of the eye". They already had one female member, artist Berthe Morisot, who became Cassatt's friend and colleague.
