Herman began his career at 1410 WHTG in Asbury Park, New Jersey,[2] and then moved to Philadelphia to become WMMR's first rock DJ. His show, dubbed 'The Marconi Experiment', debuted on April 29, 1968. The first song played on the show was "Flying" by The Beatles over the intro of which Herman recited these words: "Arise my heart, and fill your voice with music. For he who shares not dawn with his song, is one of the sons of ever darkness". He then moved to 95.5 WABC-FM in New York, which would later become WPLJ.
Most notably, he later became the morning drive time host on WNEW-FM, where he was on the air from 1972 to 1982, 1986 to 1991 and then again from 1996 until the station ended its rock format in 1998. He was one of the station's best-known voices.[3] Herman was also heard on New York classic rock station 92.3 WXRK (now WINS-FM). He was included on the Rock and Roll Hall of Fame's list of notable disc jockeys.[4] During the early to mid 1990's, he worked for the same station as Howard Stern in New York, and would sporadically call into Howard's show.[citation needed]
Six months later in October, Herman was arrested by federal authorities at the airport in Saint Croix, U.S. Virgin Islands, after going there from his vacation home in the area. The criminal complaint stated he expected to meet a woman and her six-year-old daughter, whom he allegedly believed was being brought for a sexual encounter with him. The 36-year-old woman who was "willing to let him have sex with her daughter 'Lexi'" at his St. Croix home was actually a Homeland Security agent who'd been "chatting him up online since November. ... 'I find girls that age incredibly sexy, soft, and their innocence is also a huge turn-on for me,' investigators said the 77-year-old Airmont, Rockland County, resident unwittingly told investigators who set up the sting. 'Age 6 is the perfect time to start her being loved that way.' ... [Herman] also promised not to hurt [the girl], though he admitted he might have to be 'forceful,' investigators said." After Herman also allegedly "bought a pair of plane tickets for the mother and daughter" he was charged with transportation with intent to engage in criminal sexual activity.[3][5] His unnamed attorney claimed Herman was sexually interested in the mother, not the girl, it was reported after Herman's death.[6]
