This classic, first published in 1937 and reprinted in 1999 with a foreword by Dr. Richard Masland, former president of the World Federation of Neurology, is a tribute to a man who, more than any other, aroused the attention of the scientific community and provided the sound educational principles on which much teaching of individuals with dyslexia today is based. The collection of papers reprinted in this book interprets the essence of Dr. Orton’s pioneering work in the field of developmental dyslexia.
