Born into an elite, well-connected family (a scion of the influential Montt family), Teresa received a privileged education focused on languages, music (piano and singing), and social graces aimed at securing a “good” marriage. She was multilingual, fluent in English, French, Italian, and Portuguese, and wrote some of her diaries in French. From a young age, she displayed a creative, restless spirit that clashed with the submissive role expected of women in Chile’s upper-class society.

In 1910, at just 17, she married Gustavo Balmaceda Valdés (eight years her senior and related to former Chilean president José Manuel Balmaceda), despite opposition from both families. The couple had two daughters, but the marriage was troubled by his jealousy and alcoholism, her growing independence, and frequent moves between cities like Valdivia and Iquique. During these years of relative solitude, she began writing privately, kept diaries, and published under the pseudonym “Tebac” (or similar). She was influenced by Spanish feminist Belén de Sárraga and Chilean leftist thinker Luis Emilio Recabarren, which fueled her emerging anarcha-feminist views emphasizing women’s autonomy and independence.

Marital conflicts escalated when Teresa fell in love with her husband’s cousin. In 1915, at age 22, her family and husband confined her to the Convent of the Precious Blood (La Preciosa Sangre) in Santiago as punishment for alleged adultery. Separated from her young daughters, she endured profound isolation and began a harrowing personal journal documenting her despair, loss, and first suicide attempt in March 1916.

In June 1916, with help from the Chilean poet Vicente Huidobro (who became her lover and companion), she escaped the convent and fled to Buenos Aires, Argentina. This marked the start of her life in exile and greater literary freedom. She embraced bohemian intellectual circles, collaborated with magazines like Nosotros, and rejected traditional bourgeois values. She lived nomadically, traveling to Madrid, Barcelona, New York (where she tried but failed to join the Red Cross, reportedly mistaken for a German spy during World War I), London, and Paris.

Her life was further scarred in 1917 when a young Argentine poet, Horacio Ramos Mejía (age 22), committed suicide in front of her due to unrequited love and her refusal to commit fully. This event deeply traumatized her and inspired some of her most poignant writing.

Teresa published several works during her brief career, blending surrealist elements, eroticism, spirituality, prose poetry, and intimate diary-like fragments. Her themes often explored love, death, grief, female independence, oppression, and the tension between sensuality and sorrow. She was known for sensual, incantatory language that mixed Catholic, pagan, and personal imagery.

She also left unpublished diaries and fragments, some blending autobiography, poetry, and reflections on death as a form of liberation or “warm bath” oblivion. Her work stood out for its visceral honesty, sensuality, and feminist undertones amid a male-dominated literary scene.

In 1920, Teresa briefly reunited with her daughters in Paris, but their subsequent departure left her devastated. Already in fragile health and grappling with depression, exile, and separation from her children (whom she could not easily see or bring to Chile without facing social judgment), she overdosed on Veronal (a barbiturate) on Christmas Eve 1921 at Hôpital Laennec in Paris. She lingered in agony before dying at 28. She is buried in Père Lachaise Cemetery. One of her final reflections captured her exhaustion: “To die, after feeling everything and being nothing…”

Though somewhat forgotten in her lifetime and immediately after—partly due to scandal surrounding her intimate, erotic writings and unconventional life—Teresa Wilms Montt is now recognized as a pioneering voice in Latin American feminism and modernist literature. Her rebellion against patriarchal constraints, convent confinement, and pursuit of artistic and personal freedom resonate as both personal tragedy and social prophecy. She embodied the struggles of women seeking independence in conservative societies, influencing later discussions of gender, sensuality, and creativity. Her diaries and poems continue to be studied and translated, with renewed interest in English and other languages highlighting her as “the genius of the broken souls” or a woman “not suitable for young ladies.”

The most famous scene involves a high-speed chase along the winding Moyenne Corniche above Monaco. Ironically, this was the same stretch of road where Grace Kelly would later lose her life in a car accident in 1982.

The location of the original car used in the film remains unknown. In a 2006 episode of History Detectives, a car claimed to be the original was proven false after a VIN comparison. However, Prince Albert II of Monaco purchased a meticulously restored replica in 2012 for the Prince’s car collection to honor his mother’s legacy.
