Marie Louise Killick (in some sources Maria) (died 1964) was an English audio engineer who patented the truncated-tip sapphire stylus in 1945 for playing gramophone records.[1]
Following a lapse in the patent, she was involved from 1953 in a lawsuit against Pye Ltd. (Killick v Pye Ltd) for their infringement of her patent. Killick won the suit in 1958,[2] but her bankruptcy in the following year prevented her from profiting from the outcome.[3][4][5]
