Robert Galbraith is the pen name for J.K. Rowling (Joanne Rowling). Rowling states that she chose Robert Galbraith since it was one of her favorite male names, because her hero is Robert F. Kennedy, and because she hadn’t used the name for a character in any of her many novels (most notably, Harry Potter). The last name derives from her desire to be called Ella Galbraith as a child even though she has no memories of meeting anyone with the name Galbraith.
