There are too many heroes in this book to describe them all, but Sue Levi-Pearl, as Medical and Scientific Liaison of the TSA, and Arthur and Elaine Shapiro, who demonstrated that TS symptoms responded to haloperidol, perhaps contributed most to the research advances thus far. Unfortunately, Arthur Shapiro died several years ago, but research into the understanding and treatment of TS has been ably continued, especially by the group at Yale under the leadership of Donald Cohen, James Leckman, and David Pauls.
