Fenton was born into a Lancashire merchant family. After graduating from London with an Arts degree, he became interested in painting and later developed a keen interest in the new technology of photography after seeing early examples at The Great Exhibition in 1851. Within a year, he began exhibiting his own photographs. He became a leading British photographer and instrumental in founding the Photographic Society (later the Royal Photographic Society). In 1854, he was commissioned to document events occurring in Crimea, where he became one of a small group of photographers to produce images of the final stages of the Crimean War.
