Thelma Sykes is a naturalist and printmaker and was born in Yorkshire. After completing a degree in English she settled in Cheshire close to the Dee Estuary, a source of inspiration and subject matter. She came to printmaking later in life and without formal training. Her work as a programmer analyst in the early days of computing contrasted with a growing reputation for illustrations within books of ornithological reference, but it was in the freedom of the linoleum block that she found her medium.
Elected to the Society of Wildlife Artists, in the Federation of British Artists, in 1999, she exhibits at the Mall Galleries in London. Her work is shown widely in group and solo exhibitions in the UK and Europe and she was exhibited in the Chinese Festival of Printmaking in 2000 at Chong Qing. Several of her prints are now held in public collections.
