Rachael Denhollander had the first word and the last one.

A former gymnast who became a lawyer and a coach, Ms. Denhollander told The Indianapolis Star in 2016 that Dr. Lawrence G. Nassar had molested her as a child.

She had just read a report in The Star about U.S.A. Gymnastics’ mishandling of sexual misconduct allegations against coaches. But no one had yet spoken up about Dr. Nassar, who molested young athletes for about two decades while pretending the abuse was therapy.

The Star soon published an article about the doctor, based on reports from two former gymnasts. One remained anonymous. The other was Rachael Denhollander — front and center, all alone there.
