I want to know the answer to the following question:
Who ran the Boston School for Deaf Mutes?
All the background I'm provided with is that "Bell's father was invited by Sarah Fuller, principal of the Boston School for Deaf Mutes (which continues today as the public Horace Mann School for the Deaf), in Boston, Massachusetts, to introduce the Visible Speech System by providing training for Fuller's instructors, but he declined the post in favor of his son.". Is that enough to answer the question?
