Phyllis Forbes Dennis (31 May 1884 – 22 August 1963) was a British novelist and short story writer who wrote under her birth name, Phyllis Bottome. In 1935, her novel Private Worlds was made into a film. Set in a psychiatric clinic, Bottome's knowledge of Individual psychology proved useful in creating a realistic scene. Bottome saw her share of trouble with Danger Signal which the Hays Office forbade from becoming a Hollywood film. Germany became Bottome's home in the late 1930s, and it inspired her to pen The Mortal Storm, a film which was the first to mention Hitler's name and be set in Nazi Germany. Bottome was an active anti-fascist. In total, four of her works – Private Worlds, The Mortal Storm, Danger Signal, The Heart of a Child – were adapted to film. In addition to fiction she is also known as an Adlerian who wrote a biography of Alfred Adler.
