Pierre Robert, the legendary radio personality whose voice defined Philadelphia’s rock music scene for more than four decades, was found dead in his home on Wednesday, October 29, 2025. He was 70 years old.
Robert, whose name was pronounced “Ro-Bear,” was discovered at his residence on Wednesday, according to Beasley Media Group, the parent company of 93.3 WMMR. Authorities have indicated no foul play is suspected, though the circumstances surrounding his passing remain under investigation. The specific cause of death has not been released.
Born William Pierre Robert in California, the disc jockey began his broadcasting career at San Francisco’s KSAN rock station before relocating to the East Coast. He joined WMMR in 1981, launching what would become one of the most enduring careers in American rock radio. For 44 years, Robert served as the midday host, broadcasting from 10:30 a.m. to 2 p.m. weekdays to listeners across southeastern Pennsylvania, southern New Jersey, Delaware and parts of Maryland.
Robert’s show became a Philadelphia institution, marked by his signature greeting, “Greetings, Citizens,” and his encyclopedic knowledge of rock music. His daily programming featured popular segments including “Noontime Workforce Blocks,” “Pierre’s Vinyl Cut,” exclusive artist interviews and live in-studio performances. He also delivered “On This Day” history lessons that connected listeners to rock and roll’s rich past.
Beyond his on-air presence, Robert immersed himself in Philadelphia’s live music community. He attended concerts at venues ranging from intimate clubs to packed stadiums, greeting fans with the warmth of an old friend. In 2019, his contributions to the city’s cultural landscape earned him a star on the Philadelphia Music Alliance Walk of Fame.
The DJ’s commitment to community service matched his passion for music. Robert regularly hosted and promoted charitable initiatives, including the AIDS Walk and MANNA’s Pie in the Sky fundraiser, which provides Thanksgiving meals to people and families battling serious illness. His generosity extended to supporting all of WMMR’s charitable endeavors.
Just three days before his death, Robert shared a glimpse of his Philadelphia life on Instagram. In what would become one of his final posts, he photographed himself reading a book and drinking coffee on a park bench in Rittenhouse Square. He wrote about the simple pleasure of watching the world drift by on a Sunday afternoon, calling the moment “pretty close to perfection.”
Tributes poured in from across the music industry following news of Robert’s death. Rock icon Jon Bon Jovi remembered him as someone who genuinely loved music of all types and championed musicians at every stage of their careers, from local artists to established stars. Bon Jovi noted that Robert’s voice helped the hungry and homeless, emphasizing that the DJ cared deeply about making the world a kinder place.
Preston Elliot and Steve Morrison, hosts of WMMR’s morning show, paid tribute to their colleague and friend. They reflected on Robert’s profound impact, noting his immeasurable influence on the station and its listeners. “Pierre’s impact is immeasurable,” Preston stated. “I’ve never met a better and bigger music fan in my life, and when I tell you he had a profound love for music, for rock & roll, for presenting that music to people – it was all in his heart.”
Morrison emphasized Robert’s authenticity and genuine care for others. The hosts later wrote that WMMR served as Robert’s pulpit, where he preached the gospel of rock and roll, providing common ground for listeners to share.
Caroline Beasley, chief executive officer of Beasley Media Group, expressed the company’s grief in an official statement. She noted that Robert’s unwavering love for music and deep connection with listeners made him one of radio’s most enduring and beloved voices.
Following Robert’s death, WMMR suspended its regular programming on Wednesday to mourn the loss. By Saturday, hundreds of fans and colleagues gathered at Rittenhouse Square for a celebration of life, honoring the man who had become one of Philadelphia’s most recognizable celebrities.
Tributes also appeared on the marquees of Philadelphia concert venues including Xfinity Mobile Arena, the Met and the Fillmore on the evening his death was announced. The outpouring reflected Robert’s unique position at the intersection of music, radio and Philadelphia culture.
Robert had signed a contract extension with WMMR in January 2024, solidifying his commitment to the station and its listeners for years to come. The station has not announced plans for a permanent replacement.
