Seymour was living aboard a Dutch sailing
smack when he married Sally Medworth, an Australian
potter and artist in 1954. In this they travelled around the waterways and rivers of England, journeys later described in
Sailing through England. As their first daughter grew older they felt that a land-base would be more suitable. They leased two isolated
cottages on of land near
Orford in Suffolk. These 5-acres are still called Seymour's Bit by the current owner. The manner in which they developed
self-sufficiency on this
smallholding is recounted in
The Fat of the Land (1961). At the end of the 1960s, Seymour, along with other radical voices like
Herbert Read,
Edward Goldsmith,
Leopold Kohr and
Fritz Schumacher, provided a stream of articles for the journal
Resurgence edited from 1966 to 1970 by
John Papworth. In 1964 the family moved to a farm near
Newport, Pembrokeshire. The 1970s saw Seymour's publication rate reach its peak. In 1973 John and Sally wrote
Self-Sufficiency and in 1976
The Complete Book of Self-Sufficiency was published. Appearing shortly after the publication of E.F. Schumacher's
Small Is Beautiful: A Study of Economics As If People Mattered (1973) and ''
The Good Life's first showing on British television (1975), the sales of the book exceeded all expectations. It was also set to establish the reputation of two young publishers, Christopher Dorling and Peter Kindersley who had commissioned and edited the work. In addition to self-sufficiency he wrote four guide books in the Companion Guide'' series. John also made many television programmes: an early series followed the footsteps of
George Borrow's
Wild Wales (1862). In the early 1980s he spent three years making the BBC series
Far From Paradise (with
Herbert Girardet) which examined the history of
human impact on the environment. His farm in Wales welcomed visitors seeking guidance on the smallholder's life, a project which continued when he moved to
County Wexford in Ireland. Here in 1999 he was taken to court for destroying a crop of GM sugar beet. For the last years of his life, he lived back on his old Pembrokeshire farm with his daughter's family. He died there on 14 September 2004 and is buried in the top field in an orchard that he planted. ==Legacy==
