From Wikipedia, the free encyclopedia Wendy Mary Beckett (25 February 1930 – 26 December 2018), better known as Sister Wendy, was a British religious sister and art historian who became well known internationally during the 1990s when she presented a series of BBC television documentaries on the history of art. Her programmes, such as Sister Wendy's Odyssey and Sister Wendy's Grand Tour, often drew a 25 percent share of the British viewing audience. In 1997 Sister Wendy made her US debut on public television and that same year The New York Times described her as "a sometime hermit who is fast on her way to becoming the most unlikely and famous art critic in the history of television."
