Charles Salvatore "Chuck" Panozzo (born September 20, 1948) is an American musician best known as a co-founder of the rock band Styx.

[2] Panozzo grew up in a working-class Italian Catholic neighborhood on the south side of Chicago, Illinois.

Panozzo still tours in Styx, but is a part-time member, as a result of his body growing weaker through his battle with AIDS.

According to Panozzo, he first realised his homosexuality when at age seven, he had broken his leg, and in school when the fire alarm went off, an older student had to help him out.

[3][7] In 2001, at the Human Rights Campaign annual dinner, in front of 1,000 guests, Panozzo announced that he is gay and is living with HIV.
