The Brothers Grimm were Jacob (1785 - 1863) and Wilhelm (1786 - 1859), German academics and cultural researchers who collected old European folk stories. Their published collections of folk and fairy tales remain famous as Grimm's Fairy Tales, and contain stories such as Aschenputtel (Cinderella), Der Froschkönig (The Frog Prince), Hänsel und Gretel, and Schneewittchen (Snow White).

Johann Ludwig Tieck (1773 - 1853) was a German poet, novelist, critic and translator of the Romantic movement. He published a collection of Märchen - folk or fairy tales - with titles such as Die Elfen, Der Runenberg, and Der blonde Eckbert.

 Mary Shelley (1797 - 1851) first conceived of the idea for her most famous work - Frankenstein: or, The Modern Prometheus - in 1816, after discussing with her husband, Percy Bysshe Shelley, and their friend Lord Byron, the subject of galvanism and the possibility of bringing a corpse back to life. The essence of her novel later came to her in a waking dream. The seed of the novel, however, was planted earlier than this, with the premature and still-birth of her first child.

 Emily Elizabeth Dickinson (1830 - 1886), was an American poet -  a very private person and a homebody by choice. Her poems were unconventional in form for the era, with broken rhymes and seemingly random capitalisation and punctuation, and few were published during her lifetime. The first collection of her work was published in 1890.

This refers to the Hans Christian Andersen fairytale The Princess and the Pea. It tells of a princess who is made to sleep on a bed of 20 mattresses and featherbeds, with - unbeknown to her - a pea placed under the bottom mattress, to prove to the prince who wants to marry her that she is a real princess. In the morning, on being asked how she slept, she replies that she didn't sleep a wink, as she was tossing and turning all night, and has woken bruised all over. The prince rejoices in her sensitivity, as it proves that she is a real princess, and therefore suitable to be his wife.
