The story of the word

Rudolf Berlin, a Stuttgart ophthalmologist, coined it in 1887 for patients who had lost the ability to read after brain injury. The developmental sense, applied to children who never acquired it easily, came from the British physician W. Pringle Morgan in 1896. Δυσ- reverses a word rather than negating it, the same prefix in dyspepsia and dystopia.
