Dyer was the son of a jeweller in the
City of London. His parents were
dissenters, and he was intended for the ministry. After a school kept by
John Ward near
Moorfields, he was sent to
Philip Doddridge's
dissenting academy at
Northampton. He went to the
University of Glasgow, and then the
University of Leyden, where he matriculated 16 September 1743 and stayed two years. He returned to England a classical scholar and mathematician, knowing French, Italian, and Hebrew, and a student of philosophy. He refused, however, to become a minister, or to take to any regular work, preferring to spend his time in literary society. He was an original member of the
Ivy Lane Club formed by
Samuel Johnson in the winter of 1749, which met weekly at the King's Head inn. Through the influence of
Samuel Chandler he obtained the work of translating into Latin a number of tracts left by
Daniel Williams, the founder of the library; but he tired of this task. After a visit to France he resolved to translate
François-Vincent Toussaint's
Les Mœurs, but after the first sheets were printed stopped work Dyer's means at this time were very limited, his father having died and left the bulk of his property to his widow and eldest son and daughter. Johnson and
Sir John Hawkins wanted Dyer to write a life of
Erasmus, but he revised an old edition of
Plutarch's
Lives. For this edition (published by
Jacob Tonson in 1758) he translated the lives of
Pericles and
Demetrius, and revised the whole work. He had also acted as tutor in Greek to
Richard Gough. In 1761 he was elected a
Fellow of the Royal Society, and in 1766 was put on the council. He joined the
Literary Club on its formation in 1764, where he was influential. Through this club Dyer first formed the acquaintance of
Edmund Burke, to whom he later became close. Chamier, another member, obtained for Dyer an appointment in connection with the war office. By the death of his mother and brother Dyer came into possession of £8,000, which he invested in
East India Company stock, wishing to become a director. Failing in this, he speculated disastrously, at the suggestion of Johnson, in annuities on the estate of
Ralph Verney, 2nd Earl Verney. Immediately after his loss he was seized with an attack of
quinsy, from which he died 15 September 1772. It was hinted that he had committed suicide. The money he left was insufficient to pay for his funeral. ==Reputation==
