[Michlib-l] series from th 1980's

Colleagues! I have a friend who is trying to track down an older book she read as a child (approx. 1983). Here is her description: I read a book from what I believe was a series of biographies. The book I read was about Harry Houdini and had, I believe, brown cover. The other books in the series all had covers of different colors. It's a long shot but does this sound familiar to anyone?
