The son of Henry Malcolm GEOFFROI, London-born Harry was brought to Penzance as a baby when his father was appointed the first director of the Penzance School of Practical Art, which was subsequently to become known as the Penzance School of Art.

Harry became a painter and tutor at the School, and supported his parents in their sustained efforts to raise funds for the building of its permanent home in Morrab Road. The School opened in 1881 and over the next fourteen years 'became the centre for teaching, exhibiting and raising funds for local art in West Cornwall, mainly due to the efforts of the Geoffroi family.' (Waverly)

Harry was appointed to the post of Art Master at Redruth School of Art, also acting as Assistant Master (to his father) at Penzance. He died suddenly of an asthma attack on the 3 November 1896 in Penzance, and is buried there.
