Loudan was born in London and had a brilliant career, first at the Academy Schools and later in Paris, studying under Bouguereau. His Polperro painting 'Fish Sale' was his first major success, and was later engraved for a large illustration in the Illustrated London News. He went on to produce a series of sketches for the same publication, of life in Polperro. Loudan exhibited A Cornish Fish Market at Whitechapel's Cornish exhibition in 1902.
