(1848–1909). British physicist and barrister, born at Thetford, Norfolk, and educated at Cambridge. After practising as a barrister for a number of years he devoted himself to scientific research, especially in electricity and magnetism and physiological optics. He was elected a Fellow of the Royal Society in 1888 and was president of the Physical Society (1897–9). In 1899 he published Curiosities of Light and Vision, enlarging a series of lectures he gave at the Royal Institution. The so-called Bidwell's ghost is a visual phenomenon associated with after-images produced by alternating flashing lights.
