Overview

Peter Andrew Willis (born 16 February 1960) is an English guitarist and songwriter best known as a founding member of the rock band Def Leppard. He played a central part in the group's formative years, helping to shape their early hard rock sound and contributing to songwriting on the band’s first records. Willis's work is associated with the late 1970s and early 1980s period that established Def Leppard on both the British and international rock scenes.

Early career and role

Willis was an original member of the band formed in the late 1970s. As a guitarist he combined rhythm work and riff‑driven parts with occasional melodic fills, supporting the dual‑guitar approach that became a signature of the group. He shared songwriting credits on a number of the band’s early tracks and was regarded as a core creative contributor during the band’s rise from the New Wave of British Heavy Metal era into mainstream rock.

Recordings and notable albums

  • On Through the Night (appeared on the band’s debut studio record)
  • High 'n' Dry (contributed to the band’s developing sound and songwriting)
  • Pyromania (credited on the band’s third album and on early sessions)

These albums document the transition from rawer late‑70s rock into a more polished, radio‑oriented style that would bring Def Leppard international success.

Departure and subsequent recognition

Willis was dismissed from the band in 1982 and was replaced by Phil Collen. His exit occurred during a pivotal moment as the band moved toward greater commercial breakthrough. Despite leaving the group in the early 1980s, Willis’s contributions to Def Leppard’s foundational material remained part of the band’s catalogue and legacy. In recognition of that legacy, he was included as a member when Def Leppard was inducted into the Rock and Roll Hall of Fame in 2019.

Legacy and notable facts

Willis is remembered for his songwriting input and the guitar parts that helped establish Def Leppard’s early identity. Musicians and fans often cite the band’s early records for their blend of heavy riffs, melodic hooks, and emerging production techniques; Willis’s playing is part of that sound. While he withdrew from the high‑profile touring and recording that followed, his role in the band’s origin story remains widely acknowledged in histories of late 20th‑century British rock.
