John Beagles was born in Whaplode Drove,^[2] Lincolnshire, in 1844 to John and Jane Beagles, and christened on 11 June 1844.^[3] His father was a "butcher master".^[4] In 1861, John Beagles junior was recorded as a "pupil teacher".^[5]

In the 1891 census, Beagles was recorded as a "photographic publisher" in Nottingham in the household of Thomas William Stevenson, printer, who would later be his executor.^[6] Later, he traded as J. Beagles & Co. from Little Britain, London, E.C.

Beagles and his successors produced a wide variety of postcards that included celebrities, stars of stage and screen, topographical and view cards in their Phototint series, and Louis Wain's Matrimonial Cats.^[7] The company also published a long series of scenes of London life such as The Telegraph Messenger and The Shoe Black,^[8] and humorous cards during the First World War.^[9] Often they republished, in postcard form, photographic portraits made by others.^[10]

The business continued as J. Beagles & Co. Ltd. after Beagles' death.^[11]
