William Kuhn wrote the first book on Jacqueline Kennedy Onassis in publishing. Doubleday, where Jackie worked as an editor during the last two decades of her life, commissioned the book. Nan Talese, one of Jackie's colleagues, edited it.
He has also written bestselling fiction about the current Queen of England, who boards a public train (wearing a hoodie as her incognito) to visit the mothballed royal yacht in Edinburgh.
His double biography of Henry & Mary Ponsonby tells the story of a couple who served Queen Victoria, but also laughed at her when she deserved it.
He has also written about Britain's most royalist prime minister, Benjamin Disraeli, who wrote surprisingly gay novels. More surprising still, in the midst of a century famous for prudery, Disraeli got away with it.
His history of the late Victorian monarchy shows how periodically someone has to take responsibility for dragging the show into the modern age.
His novel imagining what happened during a sexier, more fun-loving Prince Harry's deployment to Afghanistan recalls the days before he was married to Meghan.
Kuhn began his career as an academic historian. The National Endowment for Humanities and the Social Science Research Council funded his research. Featured on BBC Radio Four's "Book of the Week," his books have also been translated into Spanish and Chinese. He taught history for fifteen years at Carthage College in Kenosha, Wisconsin before becoming a fulltime writer.
