Dr John Betts (1799–1875) was an English medical doctor and philanthropist who endowed schools in the Hammersmith area of London.
John Betts was born in 1799 and studied medicine from 1815 to 1821 at Marylebone Infirmary, becoming a Qualified Licentiate of the Society of Apothecaries.
He died in July, 1875, and his funeral service was held at St Peter's Hammersmith.
The Trust provided for a school with three classrooms, one each for boys, girls and infants, to accommodate 350 pupils, together with two staff cottages.
Dr Betts specified the curriculum and set up an endowment to fund the school and provide for the children's needs.
