In 1891 a student in Paris, I found myself face to face with a beautiful development of landscape painting, which was quite new to me. "Impressionism," together with its numerous progeny of eccentric offshoots, was at the time causing a great furore in the schools. Curiously enough I had been charged with copying Monet's style long before I had seen his actual work, so that my conversion into an enthusiastic Impressionist was short, in fact, an instantaneous process.
