Laurence Dreyfus, FBA (born 1952) is an American musicologist and player of the viola da gamba who was University Lecturer and Fellow of Magdalen College, Oxford.
Commuting from New York, he studied viola da gamba with Wieland Kuijken, earning two diplomas from the Brussels Conservatoire, including its Diplome supérieur with Highest Distinction.
He has published three books with Harvard University Press: Bach's Continuo Group (1986), Bach and the Patterns of Invention (1996) (which won the Otto Kinkeldey Award for best book of the year from the American Musicological Society) and Wagner and the Erotic Impulse (2010).
As a performer, Dreyfus has made a number of solo and ensemble recordings, some of which have won major awards.
In August 2015, Dreyfus was a signatory to a letter criticising The Jewish Chronicle's reporting of Corbyn's association with alleged antisemites.
