Alan Baker FRS[1] (19 August 1939 – 4 February 2018[2]) was an English mathematician, known for his work on effective methods in number theory, in particular those arising from transcendental number theory.

Baker generalised the Gelfond–Schneider theorem, which itself is a solution to Hilbert's seventh problem.[7] Specifically, Baker showed that if are algebraic numbers (besides 0 or 1), and if are irrational algebraic numbers such that the set is
Baker made significant contributions to several areas in number theory, such as the Gauss class number problem,[8] diophantine approximation, and to Diophantine equations such as the Mordell curve.[9][10]
