Adeline Virginia Woolf (; née Stephen; 25 January 1882 – 28 March 1941) was an English writer, considered one of the most important modernist 20th-century authors and also a pioneer in the use of stream of consciousness as a narrative device.

Woolf was born into an affluent household in South Kensington, London, the seventh child in a blended family of eight. Her mother, Julia Prinsep Jackson, celebrated as a Pre-Raphaelite artist's model, had three children from her first marriage, while Woolf's father, Leslie Stephen, a notable man of letters, had one previous daughter. The Stephens produced another four children, including the modernist painter Vanessa Bell. While the boys in the family received college educations, the girls were home-schooled in English classics and Victorian literature. An important influence in Virginia Woolf's early life was the summer home the family used in St Ives, Cornwall, where she first saw the Godrevy Lighthouse, which was to become central in her novel To the Lighthouse (1927).

Woolf's childhood came to an abrupt end in 1895 with the death of her mother and her first mental breakdown, followed two years later by the death of her stepsister and a mother figure to her, Stella Duckworth. From 1897 to 1901, she attended the Ladies' Department of King's College London, where she studied classics and history and came into contact with early reformers of women's higher education and the women's rights movement. Other important influences were her Cambridge-educated brothers and unfettered access to her father's vast library.

Encouraged by her father, Woolf began writing professionally in 1900. Her father's death in 1905 caused another mental breakdown for Woolf. Following his death, the Stephen family moved from Kensington to the more bohemian Bloomsbury, where they adopted a free-spirited lifestyle. It was in Bloomsbury where, in conjunction with the brothers' intellectual friends, they formed the artistic and literary Bloomsbury Group.

Following her 1912 marriage to Leonard Woolf, the couple founded the Hogarth Press in 1917, which published much of her work. The couple rented a home in Sussex and moved there permanently in 1940. Throughout her life, Woolf was troubled by her mental illness. She was institutionalized several times and attempted suicide at least twice. Her illness is considered to have been bipolar disorder, for which there was no effective intervention during her lifetime. At age 59, Woolf committed suicide in 1941 by putting rocks in her coat pockets and drowning herself in the River Ouse.

During the interwar period, Woolf was an important part of London's literary and artistic society. In 1915 she published her first novel, The Voyage Out, through her half-brother's publishing house, Gerald Duckworth and Company. Her best-known works include the novels Mrs Dalloway (1925), To the Lighthouse (1927) and Orlando (1928). She is also known for her essays, including A Room of One's Own (1929), in which she wrote the much-quoted dictum, "A woman must have money and a room of her own if she is to write fiction."

Woolf became one of the central subjects of the 1970s movement of feminist criticism and her works have since garnered much attention and widespread commentary for "inspiring feminism." Her works have been translated into more than 50 languages. A large body of literature is dedicated to her life and work, and she has been the subject of plays, novels and films. Woolf is commemorated today by statues, societies dedicated to her work and a building at the University of London.

Mary Wollstonecraft Shelley (UK: , US: ; née Godwin; 30 August 1797 – 1 February 1851) was an English novelist who wrote the Gothic novel Frankenstein; or, The Modern Prometheus (1818). She also edited and promoted the works of her husband, the Romantic poet and philosopher Percy Bysshe Shelley. Her father was the political philosopher William Godwin and her mother was the philosopher and feminist Mary Wollstonecraft.

Shelly's mother died less than a month after giving birth to her. She was raised by her father who was able to provide her with a rich if informal education, encouraging her to adhere to his own anarchist political theories. When she was four, her father married a neighbour with whom Shelley came to have a troubled relationship.

In 1814, Shelley began a romance with one of her father's political followers, Percy Bysshe Shelley, who was already married. Together with her stepsister, Claire Clairmont, she and Percy left for France and travelled through Europe. Upon their return to England, Shelley was pregnant with Percy's child. Over the next two years, she and Percy faced ostracism, constant debt and the death of their prematurely born daughter. They married in late 1816, after the suicide of Percy Shelley's first wife, Harriet.

In 1816, the couple famously spent a summer with Lord Byron, John William Polidori and Claire Clairmont near Geneva, Switzerland, where Shelley conceived the idea for her novel Frankenstein. The Shelleys left Britain in 1818 for Italy, where their second and third children died before Shelley gave birth to her last and only surviving child, Percy Florence Shelley. In 1822, her husband drowned when his sailing boat sank during a storm near Viareggio. A year later, Shelley returned to England and from then on devoted herself to the upbringing of her son and a career as a professional author. The last decade of her life was dogged by illness, most likely caused by the brain tumour which killed her at age 53.

Until the 1970s, Shelley was known mainly for her efforts to publish her husband's works and for her novel Frankenstein, which remains widely read and has inspired many theatrical and film adaptations. Recent scholarship has yielded a more comprehensive view of Shelley's achievements. Scholars have shown increasing interest in her literary output, particularly in her novels, which include the historical novels Valperga (1823) and Perkin Warbeck (1830), the apocalyptic novel The Last Man (1826) and her final two novels, Lodore (1835) and Falkner (1837). Studies of her lesser-known works, such as the travel book Rambles in Germany and Italy (1844) and the biographical articles for Dionysius Lardner's Cabinet Cyclopaedia (1829–1846), support the growing view that Shelley remained a political radical throughout her life. Shelley's works often argue that cooperation and sympathy, particularly as practised by women in the family, were the ways to reform civil society. This view was a direct challenge to the individualistic Romantic ethos promoted by Percy Shelley and the Enlightenment political theories articulated by her father, William Godwin.

Count Lev Nikolayevich Tolstoy (; Russian: Лев Николаевич Толстой, tr. Lev Nikoláyevich Tolstóy; [lʲef nʲɪkɐˈlaɪvʲɪtɕ tɐlˈstoj] (listen); 9 September [O.S. 28 August] 1828 – 20 November [O.S. 7 November] 1910), usually referred to in English as Leo Tolstoy, was a Russian writer who is regarded as one of the greatest authors of all time. He received multiple nominations for Nobel Prize in Literature every year from 1902 to 1906, and nominations for Nobel Peace Prize in 1901, 1902 and 1910, and his miss of the prize is a major Nobel prize controversy.

Born to an aristocratic Russian family in 1828, he is best known for the novels War and Peace (1869) and Anna Karenina (1877), often cited as pinnacles of realist fiction. He first achieved literary acclaim in his twenties with his semi-autobiographical trilogy, Childhood, Boyhood, and Youth (1852–1856), and Sevastopol Sketches (1855), based upon his experiences in the Crimean War. Tolstoy's fiction includes dozens of short stories and several novellas such as The Death of Ivan Ilyich (1886), Family Happiness (1859), and Hadji Murad (1912). He also wrote plays and numerous philosophical essays.

In the 1870s Tolstoy experienced a profound moral crisis, followed by what he regarded as an equally profound spiritual awakening, as outlined in his non-fiction work A Confession (1882). His literal interpretation of the ethical teachings of Jesus, centering on the Sermon on the Mount, caused him to become a fervent Christian anarchist and pacifist. Tolstoy's ideas on nonviolent resistance, expressed in such works as The Kingdom of God Is Within You (1894), were to have a profound impact on such pivotal 20th-century figures as Mahatma Gandhi and Martin Luther King Jr. Tolstoy also became a dedicated advocate of Georgism, the economic philosophy of Henry George, which he incorporated into his writing, particularly Resurrection (1899).
