Frank Newman Turner, NDA, NDD, FNIMH, (11 September 1913 – 28 June 1964) was a British pioneering organic farmer, writer and broadcaster, who, based on his experience of natural treatment of animals, later became a consulting medical herbalist and naturopath.

After managerial positions on farms in Yorkshire, East Anglia, and Wales, he moved to London to work as an advisor for cattle feed suppliers and later joined the Potato Marketing Board.

Newman Turner registered as a conscientious objector (CO) in 1940 and became the manager of Goosegreen Farm, near Bridgwater in Somerset, which was run by a group of pacifists and Quakers as a training centre for COs who were required to work on the land.

[7] Visitors to Goosegreen Farm included the author and organic farmer, Robert Henriques, Fyfe Robertson, of Picture Post, Lady Eve Balfour, founder of the Soil Association, Laurence Easterbrook, Juliette de Baïracli Levy, Doris Grant, author of Your Daily Bread, and writers and artists such as Elspeth Huxley, Reginald Reynolds, and Ethel Mannin, as well as Richard de la Mare, the agricultural editor of the publisher Faber & Faber which later published Newman Turner's books.

Newman Turner was in demand as a spokesman on natural farming and animal rearing, appearing regularly on regional radio stations and, for a time, on BBC television's The Smokey Club, a pet care programme presented by the zoologist George Cansdale.

The Farmer had featured a supplement on organic horticulture and, in 1957, Newman Turner launched The Gardener, Small Livestock and Pet Owner as a monthly magazine with eminent horticulturist W. E. Shewell-Cooper, as associate editor, and Lawrence D. Hills a regular contributor.

Lawrence Hills, a well known alpinist and horticultural writer, founded the Henry Doubleday Research Association (now Garden Organic) in 1954 and invited Newman Turner to become its first president, a position he held until his death.
