Sir John Claud Fortescue Fryer KBE FRS FRSE (13 August 1886 – 22 November 1948) was an English entomologist.
[1][2] He was born at The Priory in Chatteris, Cambridgeshire, as the son of Herbert Fortescue Fryer, a farmer and amateur entomologist, and his wife Margaret Katherine Terry.
In 1908 and 1909, he spent time in the Seychelles and Aldabra Islands on a Percy Sladen Trust expedition to study the fauna and physiography.
[5] His application citation read: "[Fryer] is an entomologist, his early researches on the genetics of mimetic polymorphism in Papilio polytes are classic.
As the first entomologist employed by the Board of Agriculture, and later as Director of the Board's Plant Pathology Laboratory he established the advisory and quarantine services in this country on such sound scientific lines that they enabled the great development of agriculture during the war to take place.
