ABSTRACT
The learning disability (LD) now identified variously as developmental reading disorder, dyslexia, or specific reading disability (Hynd & Cohen, 1983) was brought to general attention by the turn-of-the-century clinical reports of Pringle Morgan (1896) and James Hinshelwood (1895) in Great Britain, among others, under the guise of the term congenital word blindness. Hinshelwood summarized many of these cases in his 1917 monograph of that name. Subsequent to Hinshelwood's work, the most influential single investigator was Samuel Orton (1925, 1928, 1937), who contributed numerous reports of clinical cases, theoretical speculation about proximal causation, and suggestions for treatment techniques. Although Orton coined the term strephosymbolia to describe the condition, he also often used the term specific reading disability (Duane, 1985).
