A radio legend whose voice was as familiar to Philadelphia listeners as the Liberty Bell’s silhouette, William Pierre Robert, died on Wednesday morning at his home at the age of 70. The beloved WMMR midday host, known for greeting his audience with his signature phrase “Greetings Citizens,” had been a fixture on Philadelphia’s airwaves for 44 years, becoming synonymous with the city’s rock music culture.
Born on August 1, 1955, in Truckee, California, Robert began his career at San Francisco’s 94.9 KSAN-FM before relocating to Philadelphia in 1981. His journey to radio stardom wasn’t immediate; initially rejected for an on-air position at WMMR, he briefly worked at a health food store before joining the station’s music library. This persistence eventually led to his iconic status as the “heart and soul of WMMR,” according to parent company Beasley Media Group.
The California native’s road to radio royalty included rejection, a detour at a health food store, and unwavering determination.
Robert’s relaxed, hippie-like demeanor and genuine passion for rock music endeared him to generations of listeners throughout Philadelphia, its suburbs, South Jersey, and Delaware. His casual approach to show timing became so renowned that fans affectionately coined the term “Pierre Standard Time” for his characteristically delayed or extended segments.
The radio personality’s influence extended beyond broadcasting, earning him significant recognition including a star on Philadelphia’s Walk of Fame along South Broad Street in 2019. Notable musicians like Jon Bon Jovi, Dave Grohl, and Eddie Vedder granted him rare interviews, further cementing his stature in American rock radio. His mastery of audience engagement during live broadcasts created an intimate connection between listeners and performers rarely achieved in radio.
No cause of death has been publicly disclosed, though reports indicate no foul play is suspected. The sudden passing occurred before his scheduled midday show, shocking colleagues and listeners alike.
Robert’s legacy as a cultural icon who bridged generations of rock enthusiasts remains indelible. His annual tradition of playing Arlo Guthrie’s “Alice’s Restaurant” multiple times during Thanksgiving broadcasts became one of his most cherished programming staples. Throughout his career, his infectious optimism provided comfort to countless listeners during difficult days. Beyond his on-air presence, Robert understood the importance of diverse income in the music industry, often advising emerging artists about revenue opportunities beyond traditional performances. Beasley Media Group described him as “one of radio’s most enduring and beloved voices,” while fans and peers across media platforms expressed profound admiration and grief.
Philadelphia has lost not just a radio personality, but a cultural giant whose impact on the city’s music scene spanned four remarkable decades.
