Born deaf, Rathaway was later cured by his parent's money and research. He became obsessed with sound and found how to control peoples' minds with it, through a pipe he developed. Eventually, he became a member of the Flash's Rogue Gallery.
The Pied Piper was originally inspired by the classic tale "The Pied Piper." In the classic tale the Pied Piper was hired to get rid of a bunch of rats from a village. So the Pied Piper played a tune on his flute which hypnotized the rats. The rats followed him and he led the rats to a river where they drowned. The Pied Piper then returned to the village expecting to be paid but the townspeople refused to pay him. Angered the Pied Piper began to play his flute again but this time the children of the village followed him and he led them up and into the mountains where they were never to be seen again.
The comic book incarnation of the Pied Piper drew inspiration from this Pied Piper and was created by John Broome and Carmine Infantino. The Pied Piper made his first comic book appearance in The Flash #106.
A Member Of Flash's Rogues
The Pied Piper began as one of The Flash's villains. Eventually a number of The Flash's villains grouped together to form The Rogues.
A Rogue No More

He is one of the first characters of the DC company to 'come out' as gay, revealing his orientation to the current Flash of the time, Wally West. He fought alongside Wally many times, and became good friends with Wally and Linda Park (then Wally's girlfriend, now his wife). The Pied Piper's parents were murdered by the Mirror Master who framed Piper for the murder.
Batting For The Good Guys
The Pied Piper is one of the few Rogues who have turned good, and although he has tendencies to turn back to evil occasionally, he remains, deep down, a good person.

A Rogue Once More

The Pied Piper did not actually take part in Bart's killing, though he was present at the time.

All With Good Wishes

After Bart's death though the Rogues', himself included are caught and sent to the planet "Salvation." His good friend Trickster is killed before getting their though. When he returns to Earth he finds a note telling of the Trickster's last wishes to destroy the Rogue's. Pied Piper sees the evil of the Rogue's and decides to fulfill this wish of The Trickster. When he finds the Rogues' he finds them in battle against Kid Zoom. He helps them stop Kid Zoom but the Rogues' take things too far and kill Kid Zoom. Pied Piper takes this very hard as he sees again that whilst he did not do the killing that he was partly responsible for the death of another child. He turns himself over to the police afterward as a sort of penance.
