VALDES, Jose Manuel, Peruvian physician, born in Lima about 1780; died there in 1840. He was of negro parentage, and studied in the convent of San Ildefonso under the protection of an Augustinian friar, but chose the medical profession, as the church, the army, and the civil service were closed to him by the prejudices of the time. In 1807 he was graduated in medicine in the University of San Marcos, where he read one of his three dissertations that were afterward printed in Madrid.
