Final answer:
Florence Balcombe is most known for her demand to destroy all copies of 'Nosferatu', a silent film that took inspiration from her late husband's novel without permission.
Step-by-step explanation:
Florence Balcombe is probably most known today for demanding that all copies of Nosferatu be destroyed. This assertion is true. Florence Balcombe was not known for her skill as a nurse nor did she have any significant relationship with nursing theories such as the miasmatic theory, which is more commonly associated with Florence Nightingale. She was also not the mother of Abraham "Bram" Stoker, but rather his widow. As for the term "The Bloofer Lady," it is a character description from Bram Stoker's famous novel Dracula and not a nickname for Florence Balcombe herself.
