Peter Edward Baker (1937–2008) was a notable British volcanologist, professor emeritus of Igneous Petrology in the School of Earth Sciences (now Earth & Environment), University of Leeds.

Life 
Baker graduated in Geology from University of Sheffield in 1960. He then became a PhD research student and later a research fellow at Oxford University. Baker was appointed to a lectureship at the University of Leeds (1969) and later reader (1976). He was appointed Professor of Geology at the University of Nottingham from 1978 to 1989. Following the Oxburgh review of Earth Science departments, Baker returned to Leeds. He retired in 1998.

Baker's work was mainly on volcanoes and volcanic rocks of island arcs and oceanic islands. His work began with Mount Misery volcano on the West Indian island of Saint Kitts; continuing with the volcanoes on the islands of Saint Vincent, Montserrat and Saba, Lesser Antilles. When the volcano Tristan da Cunha, in the South Atlantic, erupted in 1961, Baker joined a Royal Society expedition led by Ian G. Gass to investigate.

A lava specimen from Cook Island, South Sandwich Islands was the nearest terrestrial equivalent to some of the boulders analysed during the Mars Pathfinder mission of the late 1990s. The South Sandwich Islands are the type example of a primitive oceanic island-arc. Baker worked there and at Deception Island, off the Antarctic Peninsula, as it had a series of volcanic eruptions (1968–70).

Baker worked on Ojos del Salado, on the Argentina–Chile border, the highest active volcano in the world. He made a geological map of Easter Island and worked on the Juan Fernandez Islands, which lie between Easter Island and Chile. Peter Baker was secretary general of the International Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI, 1975–1983) and he was on the editorial board of the Journal of Volcanology and Geothermal Research since 1976.
