About's Arthritis Guides, Carol and Richard Eustice, look at this aspect of Renoir's life in their article Renoir: Portrait of Perseverance. The BMJ's article: How Renoir Coped with Rheumatoid Arthritis is accompanied by several period photos and looks, among other things, at how it influenced Renoir's style and painting technique. Both articles left me with an even great admiration for the man and his painting achievements.
