“It would be difficult, if not impossible, to find any other disability affecting so many millions of children in the United States today, on which so much research has been done, so many thousands of articles written and yet concerning which so very little information has reached the average teacher or physician to say nothing of the parents and the public.  These children are as handicapped by the ignorance surrounding their problem as they are by the problem itself.”

Careth Ellingson 1963 Saturday Review
