Ralph Wightman (26 July 1901 – 28 May 1971) was an English lecturer, journalist, author, and radio and television broadcaster.
He wrote many books on farming and the countryside and in the 1950s and 1960s became a well-known national figure, especially as a regular guest on the BBC radio programme Any Questions?
A younger son of Tom Wightman, a farmer and butcher of Piddletrenthide in Dorset, Wightman was educated at Beaminster Grammar School and Armstrong College, Newcastle, part of the University of Durham, where he graduated BSc in agricultural chemistry.
From 1923 to 1927 he was a lecturer on agriculture for Devon County Council, then from 1927 to 1930 for Wiltshire County Council, before in 1930 returning home as Senior Agricultural Adviser to Dorset County Council. He gave up that work in 1948 to become a freelance writer and broadcaster, having begun to give talks on radio in the 1930s.
During the Second World War Wightman began to broadcast once a week to the United States on English country life, and altogether he gave 290 such "Trans-Atlantic talks". His radio work nearer home included a feature on the BBC Home Service programme Country Magazine, every week focussing on an aspect of country life in a different place around England. As a broadcaster specializing in farming and the countryside, Wightman was soon seen as the natural successor to his mentor A. G. Street, and from the 1950s on he established himself as a national figure, known for his books, his column in The Guardian, and his radio and television work. On 15 April 1957 he was Roy Plomley's guest on Desert Island Discs, choosing music by Elgar, Vaughan Williams, Mendelssohn, Strauss, Parry, Paul Robeson, and Bill Haley.
