Professor of Physical Chemistry (Cambridge)
academic title at the University of Cambridge

The Professorship of Physical Chemistry is a permanently-established professorship at the University of Cambridge, created in 1920.For the first six decades of its existence, the incumbent was also Head of the Department of Physical Chemistry – a separate entity from the then Department of Chemistry, albeit latterly occupying the same building in Lensfield Road. Following the merger of these two departments in the early 1980s, holders of this Chair have often served as head of the current unified Department of Chemistry.
Occupants of the chair to date have been:
Martin Lowry (1920–1936),proposed the Brønsted–Lowry acid–base theory
Ronald G. W. Norrish (1937–1965),Nobel laureate in Chemistry (1967), developed the Norrish reaction
Jack Linnett (1965-1975),Master of Sidney Sussex College (1970–1975) Vice-Chancellor (1973–1975), proposed the Linnett double-quartet theory
John Meurig Thomas (1978–1987),Master of Peterhouse (1993–2002), Royal Medallist (2016), a founder of solid-state chemistry
Sir David King (1988–2006),Master of Downing College (1995–2000), Government Chief Scientific Adviser (2000–2008), chair of Independent SAGE (2020–)
John Pyle (2007–2018),Davy Medallist (2018), co-chair of the scientific assessment panel for the Montreal Protocol
Tuomas Knowles (2023–), Corday-Morgan Prize recipient (awarded in 2017)
In addition to the 1920 professorship, the university established a second Professorships of Physical Chemistry for a single tenure (i.e. as personal chair) for Brian Thrush, who held the office from 1978 to 1995.

Why this record matters
The phrase “academic title at the University of Cambridge” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Jul 11, 2026. The linked authority identifier is Q65067833. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1920, 1936, 1937 and 1965.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
