Abstract
J. Richard Ewald (1855-1921) was a German physiologist to whom we owe important insights concerning vestibular function. He is best known for 'Ewald's second law,' which implies that in persons who have lost inner ear function on one side, the remaining side should produce higher velocity nystagmus when the head is being rotated toward the remaining intact ear (ampullopetal), but less when the head is being rotated toward the side of vestibular loss.
