Use who to ask about a person: Who is that? Who are they? When who is the object, use do/does/did as usual: Who did you meet? But when who is the subject of the sentence, ask without do — the verb follows directly: Who made this cake? Who lives here?

Subject questions keep the verb form of a statement: Who wants coffee? (wants, with -s). To ask about things, use what; to ask about ownership, use whose.
