Helen Sinclair was born in South Wales in 1954. She studied sculpture at Wimbledon School of Art (1972- 1976). After teaching for twelve years, she has been a full-time sculptor since 1988. With her technician (traveller and writer Gary Ley) she does her own mould-making and resin casting. All her bronze sculpture is cast at the MB Fine Arts Foundry in Pembrokeshire.
Helen is currently President of the historically important Society of Women Artists.

The human figure is her primary subject : the actual figure (in movement and at rest, clothed and unclothed) and the figure as depicted by other artists in any medium and at any phase in history.
Her influences include the sculptural forms and mythology of ancient civilisations (Etruscan, Egyptian, South American), Italian Renaissance sculpture (especially Donatello) and twentieth century sculptors : Emilio Greco, Medardo Rosso, Giacometti and, most notably, Willhelm Lehmbruck. She also looks to painting for inspiration, especially Picasso, Matisse, Chagall and Modigliani.

She exhibits widely in England and Wales and annually at the Chelsea Flower Show. Solo shows include: Catto Gallery, Hampstead, St David’s Hall, Cardiff; Kooywood Gallery, Cardiff, Edith Grove Gallery, London; Fairfax Gallery, Tunbridge Wells and Chelsea; Orleans House Gallery, Surrey; Grosvenor House Hotel, London, with Flying Colours Gallery at Dover St and Cork St Galleries, London W1, Edgar Modern Gallery, Bath.
She has work in private collections in Denmark, France, Germany, Greece, Holland, Ireland, Italy, Sweden, Switzerland, Lebanon, America, Australia and New Zealand.

Her customers include Lord Melvyn Bragg, Sir Robert Clark, chef Gary Rhodes, singer Bonnie Tyler, actress Sheila Hancock, actor Arnold Schwarzenegger, poet Roger McGough and Keith Chapman (creator of Bob the Builder!).

Recent commissions include ‘The Mother and the Child’ for All Saints Church, Fulham; ‘Five Figures’ for St Mary’s Hospital, Chichester and ‘Still Sitting’ for Gary Rhodes’ restaurant, ‘Rhodes 24’, Brecon Cathedral's two metre hanging bronze crucifix, 'Doo Wah Diddy' for the Royal Free Hospital in London, 'The Four Seasons' for Marie Curie's new West Midlands Hospice in Solihull,
