Minerva McGonagall: Minerva is the Roman goddess of wisdom, war, and crafts. JK Rowling took the last name McGonagall from William McGonagall, who is celebrated as the worst poet in British history. She said that she found it amusing to think that such a brilliant woman might be a distant relative of William McGonagall.
Today is the time to celebrate Professor McGonagall’s long and distinguished career as Transfiguration teacher (38 years), and her current post as Headmistress of Hogwarts.

Dilys Derwent (Healer: 1722-1741. Headmistress: 1741-1768)
