Tim Jeal

Explorers of the Nile: The Triumph and Tragedy of a Great Victorian Adventure (2011) is about the search for the source of the Nile by John Hanning Speke, James Augustus Grant, Richard Francis Burton, Samuel White Baker, Henry Morton Stanley, David Livingstone and many others from 1856-1878. It is particularly focused on John Hanning Speke, seeking to restore his reputation, who is credited with unraveling the mystery of the source. Jeal has pitched the book as an update to Alan Moorehead's The White Nile.

The 2007 biography of Sir Henry Morton Stanley was a revisionist account that showed Stanley in a more sympathetic light. Professor John Carey in The Sunday Times accepted that Jeal's 'ardent, intricate defence of a man history has damned' had been successful, and concluded: 'Anyone who, after reading this book, imagines they would have behaved better than Stanley, if faced with the same dangers, must have a vivid imagination.'

In Baden-Powell (1989), Jeal offers a revisionist account of Lieutenant-General The 1st Baron Baden-Powell, founder of the Boy Scouts, restoring his reputation which had deteriorated during the 20th century. However, Jeal also speculated that Lord Baden-Powell was a homosexual, even a repressed one, and this sparked a great deal of attention in the popular press culminating in scouting organisations reissuing an earlier biography of Baden-Powell by William Hillcourt to dilute attention and sales of Jeal's book. In 1995, Jeal's book was the basis for a TV documentary in the Channel 4 series "Secret Lives" entitled Lord Baden-Powell: The Boy Man.

His biography, Livingstone (1973), based on private letters, diaries and archives, was the first to describe the explorer/missionary's faults and failings and to reveal the man behind the icon. It became the basis for a BBC TV documentary and a film for the Discovery Channel. Livingstone has never been out of print since first publication in 1973 and in 2013 was reissued in a revised and expanded edition by Yale University Press.

From 1966 to 1970, he worked for BBC Television in the features group.

Jeal has been writing books since the 1960s, for London and New York-based publishers. Although most of his works are fictional, he is best known for his biographies.

John Julian Timothy Jeal, known as Tim Jeal (born 27 January 1945 in London, England), is a British biographer of notable Victorians and is also a novelist. His publications include a memoir and biographies of David Livingstone (1973), Lord Baden-Powell (1989), and Sir Henry Morton Stanley (2007).

Tim Jeal was born 27 January 1945 to civil servant Clifford Freeman Jeal and Norah Margaret Sabine, daughter of Sir Thomas Edward Sabine Pasley, 3rd Baronet, and Constance Wilmot Annie Hastings, daughter of the 14th Earl of Huntingdon. Jeal was educated at Westminster School, London, and Christ Church, Oxford. Clifford Jeal, about whom his son published a memoir in 2004, was a Christian mystic and follower of the Anglican Order Of The Cross fellowship and as such practised pacifism and vegetarianism.
