Miss Ironish Clapp is the headmistress (previously deputy headmistress) of St Prowd's school in Shiz.
Out of Oz[]
She is the sister of Proctor Gadfry and is described as a stern woman, who is not afraid to speak her mind. She often tells her pupils the negative views in their behavior as she believes it will help build character better than praise. She later appears at the end of Out of Oz as a consort/lady-in-waiting to Princess Ozma.
