White was born as Eirene Botting to parents Cecil and Christine Botting. She later took her mother's maiden name, White. Her father taught Greek and Latin at St. Paul’s School. She was baptized in the Protestant Church of England but converted to Roman Catholicism at the age of 9 when her father converted. She struggled with religion and did not feel that she fitted in with the other girls at her school, many of whom were from upper-class Catholic families. She attended the Convent of the Sacred Heart, Roehampton (later Woldingham School, Surrey).
Although she is remembered as a modernist writer, she developed a terrible fear of writing after a misunderstanding when she was 15. She had been working on what was going to her first novel, which was to be a present for her father. She wanted to surprise him with a book about wicked people whose lives are changed as they discover religion. She attempted to give a detailed description of the evil characters, but, because of her lack of experience, she was unable to describe their wickedness except to say that they “Indulged in nameless vices”. The story was found unfinished by officials at her Catholic school and she was then expelled from the school without being given the opportunity to explain her book. She describes this incident as being her most vivid and tragic memory. “My superb gift to my father was absolutely my undoing” she remarked in an interview. She did not begin writing novels again until 20 years later, when her father died.
After she was expelled from the convent at Roehampton, she attended St. Paul’s Girls' School (the sister school to St Paul's School where her father taught), but did not fit in there either. When she left school she attempted to become an actress, but was unsuccessful. She then wrote for magazines and worked in advertising, where she earned £250 a year promoting Mercolized wax. She spent nine years working as a copywriter in London and she also worked for the BBC as a translator. Antonia White's translations of Colette's 'Claudine' novels were recognised for their elegance and erudition and remain the standard texts today.
In 1921 she was married to the first of her three husbands. The marriage was annulled only 2 years later, and reportedly was never consummated. She immediately fell in love again with a man named Robert, who was an officer in the Scots Guards. They never married, and their relationship was brief but intense, which led to her experiencing a severe mental breakdown. She was committed to Bethlem, a public asylum, where she spent the next year of her life.
She had described her breakdown as a period of “mania”. After she left the hospital, she spent four years participating in Freudian studies. She struggled the rest of her life with mental illness which she referred to as “The Beast”.
Her second marriage was to a man named Eric Earnshaw Smith, but this marriage ended in divorce. By the age of 30, she had been married 3 times. During her second marriage, she had fallen in love with two men. One was Rudolph 'Silas' Glossop, described as “a tall handsome young man with a slightly melancholy charm”. The other was Tom Hopkinson, then a copywriter. She had trouble deciding whom she should marry following her divorce, and she married Hopkinson in 1930. She had two daughters, Lyndall Hopkinson and Susan Chitty, who have both written autobiographical books about their difficult relationship with their mother.
Writing career and personal life
By 1931, White was married to Tom Hopkinson and was friends with novelist Djuna Barnes, and she was with Barnes when the latter wrote her now famous novel depicting a lesbian affair gone bad, Nightwood. This novel was based on Barnes's relationship with Thelma Wood. In 1933, White completed her first novel, Frost in May, which fictionalized her experiences at Catholic boarding school and her expulsion. She also began writing a second novel, but a failed marriage and mental illness hindered its completion.
Fifteen years later, she completed her second novel The Lost Traveller, which was published in 1950. In the subsequent five years, after undergoing treatment for mental illness and reconverting to Catholicism, she completed the Clara Batchelor trilogy, which includes The Lost Traveller, about her relationship with her mother and father, The Sugar House, about her first unconsummated marriage, and Beyond the Glass, about an intense love-affair followed by a breakdown, which is vividly described. As with her previous work, the trilogy was fictional, but mainly autobiographical. The four novels together narrate her life from ages 9 to 23. In 1966, she published a collection of letters entitled The Hound and the Falcon: The Story of a Reconversion to the Catholic Faith. She wrote Three in a Room, a three-act comedy, as well as many short stories, poems and juvenile fiction.
Her career as a writer seems to have been driven by the desire to cope with a sense of failure, resulting initially from her first attempt at writing, and with mental illness. She was quoted as saying, “The old terrors always return and often, with them, a feeling of such paralyzing lack of self-confidence that I have to take earlier books of mine off their shelf just to prove to myself that I actually wrote them and they were actually printed, bound, and read. I find that numbers of writers experience these same miseries over their work and do not, as is so often supposed, enjoy the process. "Creative joy" is something I haven't felt since I was fourteen and don't expect to feel again."
With regard to the content of her writing, White remarked, “My novels and short stories are mainly about ordinary people who become involved in rather extraordinary situations. I do not mean in sensational adventures but in rather odd and difficult personal relationships largely due to their family background and their incomplete understanding of their own natures. I use both Catholic and non-Catholic characters and am particularly interested in the conflicts that arise between them and in the influences they have on each other.” Two of the main themes in White’s novels are her relationship with her father and her Catholic faith.
In the introduction to Frost in May, Elizabeth Bowen describes the novel as a school story. She comments that the novel is written for adult readers, but that the language is comprehensible to an intelligent child of twelve. She writes, “We have Nanda’s arrival at Lippington, first impressions, subsequent adaptations, apparent success and, finally, head-on crash.” This plot deviates from what Bowen refers to as the normal school story only in that it does not have a happy ending. Frost in May was written during the rise of anti-school school stories after World War I. Regarding White's writing style, Bowen wrote: "Antonia White’s style as a story-teller is as precise, clear and unweighty as Jane Austen's. Without a lapse from this style Antonia White traverses passages of which the only analogy is to be found in James Joyce's Portrait of the Artist as a Young Man." This comparison suggests that White's writing is both reminiscent of 19th century realism and indicative of modernist tendencies.
