John James Sainsbury (12 June 1844 – 3 January 1928) was an English grocer and founder of what is now called the Sainsbury's supermarket chain.
Early and private life
John James Sainsbury was born on 12 June 1844 at 5 Oakley Street, Lambeth, (now Baylis Road) to John Sainsbury (baptised 1809, d. 1863), ornament and picture frame maker, and his wife Elizabeth Sarah, née Coombes (1817–1902).
During his childhood, his family moved frequently, often between rented rooms. The area in which they lived was close to the Thames wharves and to Waterloo station, which opened in 1848.
Sainsbury started work at the age of 14 years old. He may have stayed at school beyond the normal leaving age of 10 or 11, possibly helping out as a "monitor". His first job was with a grocer in the New Cut, Lambeth.
Business career
Throughout his life, Sainsbury avoided personal publicity and little evidence remains of his character. His business style was to offer competitive prices while simultaneously demonstrating higher standards of quality, service, and hygiene.
