Julie Montagu, Countess of Sandwich is not your average aristocrat. Born on the outskirts of Chicago, she describes herself as an all-American girl who unexpectedly met the future Earl of Sandwich and then married into the British aristocracy. Two decades later, Julie is the driving force behind Mapperton House, Gardens & Wildlands in Dorset, UK - widely regarded as one of England's finest manor houses. She shares her daily life with hundreds of thousands of followers via YouTube (@MappertonLive) and Instagram (@juliemontagu) as well as Facebook, Patreon and Substack. Alongside managing the estate, Julie built a successful career as a wellness entrepreneur and yoga instructor, writing several bestselling books and appearing on Bravo's Ladies of London. As a historian, she is a sought-after presenter and commentator on British history and royal affairs for both UK and US networks. In 2020, she presented An American Aristocrat's Guide to Great Estates for the Smithsonian Channel. She later launched the @AmericanCountess YouTube channel, where her production company, Living History Films, produces high-quality documentaries exploring Britain's stately homes.
