In the USA Realism engaged such major painters of the second half of the 19th century as Winslow Homer, Thomas Eakins (e.g. the Gross Clinic, 1875; Philadelphia, PA, Thomas Jefferson U., Medic. Col.) and John Singer Sargent, all of whom used their European experience to import fashionable influence to the USA. The American expatriate James McNeill Whistler moved to Paris in 1855, where he met and was influenced by Courbet. In Arrangement in Grey and Black, No. 1: Portrait of the Artist’s Mother (1871; Paris, Mus. d’Orsay) he created a refined balance between Realism and his emerging Aestheticism in a way that fits perfectly within the transition from Courbet to Manet.
