Jon Miller (born John Miller, 14 July 1921 – 30 July 2008) was a British television presenter who was best known for his appearances on the educational children's television science programme How between 1966 and 1981 with Jack Hargreaves, Bunty James and Fred Dinenage.
His mother, Edie, was a concert pianist, his father, Jack, was a shopkeeper and Yehudi Menuhin, the violinist, was a cousin.
Miller's upbringing on the English South coast began a life-long interest in marine life.
He then worked for his father's retail business, and travelled abroad extensively as a specimen collector for the Zoological Society of London.
In the early 1960s, while living in Middleton-on-Sea in Sussex, Miller was spotted by Jack Hargreaves, then Deputy Programme Controller at Southern, who recruited him to appear on How.
