Walter Parazaider, the saxophonist and co‑founder of the rock group Chicago, died on June 17, 2026, at the age of 81. He passed away in hospice care in Illinois after a long battle with Alzheimer’s disease, according to a statement released by the band and confirmed by his family.

Born March 14, 1945, in Maywood, Illinois, Parazaider began his musical journey as a clarinetist before switching to saxophone and flute. In 1967 he joined a circle of friends in Chicago that would eventually become the band Chicago. The original lineup—Peter Cetera, Terry Kath, Robert Lamm, Danny Seraphine, Lee Loughnane, James Pankow, and Parazaider—recorded the debut album Chicago Transit Authority in 1969. The group’s innovative blend of rock, jazz, and horn arrangements made it one of the first “rock‑and‑roll with horns” acts, a concept Parazaider helped conceive.

The 1970s saw Chicago release a string of chart‑topping albums and singles. Parazaider’s saxophone lines are featured on classics such as “25 or 6 to 4,” “Saturday in the Park,” and “Just You ’n’ Me.” His flute solo on “Colour My World” remains a highlight of the band’s catalog. His versatility on woodwinds contributed to Chicago’s distinctive sound and helped the group sell more than 100 million records worldwide.

Parazaider remained a member of Chicago until 2018, when he retired after a career that spanned more than five decades. In April 2021 he publicly disclosed that he had been diagnosed with Alzheimer’s disease. He expressed shock at the diagnosis but also determination to continue fighting the illness, noting that he had a good doctor and a supportive medical facility.

The band’s official statement on June 17 said, “Chicago is heartbroken at the sad news of Walter Parazaider’s passing this morning. We extend our deepest condolences to his family, friends and countless Chicago fans who are all grieving his loss today.” The statement also highlighted Parazaider’s role in forming the band’s horn section and in booking early shows in local bars, underscoring his influence on Chicago’s rise to prominence.

Parazaider’s daughter, Felicia Helen Parazaider, posted a tribute on Facebook, writing, “I love you poppy, my Pal…You coloured our world.” His wife, JacLynn, and his other daughter, Laura, survived him.

Chicago’s legacy includes multiple Grammy nominations, a 2016 induction into the Rock and Roll Hall of Fame, and a 2020 Grammy Lifetime Achievement Award. The band’s early albums, such as Chicago VI and Chicago XI, were critical and commercial successes, and the group remains a staple of classic‑rock playlists.

Parazaider’s death marks the loss of a key figure in the development of horn‑based rock. His contributions to Chicago’s sound, his long tenure, and his perseverance in the face of illness are noted by band members and music historians alike. The band has not yet announced any memorial performances, but it has expressed gratitude for his legacy.

The obituary of Walter Parazaider is a reminder of the enduring impact that musicians can have on popular music and the importance of recognizing the individuals behind iconic sounds.
