From the start of his career, Ravel appeared calmly indifferent to blame or praise. Those who knew him well believed that this was no pose but wholly genuine. The only opinion of his music that he truly valued was his own, perfectionist and severely self-critical. At twenty years of age he was, in the words of the biographer Burnett James, "self-possessed, a little aloof, intellectually biased, given to mild banter". He dressed like a dandy and was meticulous about his appearance and demeanour. Orenstein comments that, short in stature, light in frame and bony in features, Ravel had the "appearance of a well-dressed jockey", whose large head seemed suitably matched to his formidable intellect. During the late 1890s and into the early years of the next century, Ravel was bearded in the fashion of the day; from his mid-thirties he was clean-shaven.
