A ghostwriter is a professional writer who gets paid to write for another person or company. The ghostwriter will conduct all the research, unless some already exists, conduct interviews, write, edit, although will generally use professional copy editors and proof readers if they're serious, and sometimes help publish the final work if that's what the client wants. You would need a ghostwriter primarily because you either don't have the time or the experience to write a memoir or life story yourself.
