William Frederick Denning (November 25, 1848 – June 9, 1931) was a British astronomer. He devoted a great deal of time to searching for comets, and discovered several including the periodic comet 72P/Denning-Fujikawa and the lost comet D/1894 F1. The latter was the last comet discovered on British soil until the discoveries of George Alcock.
Were Denning's odd observations of so-called sleeks (swift nearby meteors, darting gleams of light) perhaps related to the psychological phenomenon known as Prisoner's Cinema? (see also Denning's articles in the Sourcebook Project, William R. Corliss).
