Born on 24 December 1900 in Valença, Rio de Janeiro, Yvonne do Amaral Pereira was a Brazilian seamstress and medium, author of several books on psychography. She died on 9 March 1984 (aged 83) in Rio de Janeiro. Yvonne do Amaral Pereira was a Brazilian medium known for her important career as a medium. 

Her father was a small businessman, Manoel José Pereira Filho, and her mother was Elizabeth do Amaral Pereira. She had five younger siblings and an older one, the son of her mother's first marriage. From what we read in her own statements in the book Recordações da Mediunidade – which was written under the assistance and supervision of the unforgettable Bezerra de Menezes – Yvonne Pereira's childhood was truly sad and painful.

When I was only 29 days old, "during a sudden attack of coughing and choking, I died".

The doctor and the pharmacist certified death by asphyxia. The wake was prepared. The supposedly deceased was dressed in a wreath of flowers and a white and blue dress. The small white coffin was ordered. The mother retired to a room, where she said a sincere and fervent prayer to Mary of Nazareth, asking for the situation to be resolved, for she did not believe that her daughter was dead. A few moments later, the child awoke in tears. All preparations were undone. The funeral was cancelled and life went on as normal. From a very young age she showed a great talent for mediumship and, throughout her life, was responsible for important messages and psychographic work. 

At the age of 5, she not only saw, but also talked to spirits. At the age of 10, by order of his father, she attended spiritist séances at home, and at the age of 12 she was given the books The Gospel According to Spiritism and The Spirits' Book, which she was to read every day, which he did, following the advice of his always kind father. At the age of 13 she began to attend practical spiritist séances, which he loved because she could see the communicating spirits. His only schooling was primary school. For financial reasons, she was unable to attend other courses, which was a great trial for her, as she loved to study and read, to the point that by the age of 16 she had already read works by great authors such as Goethe, Bernardo Guimarães, José de Alencar, Alexandre Herculano and Arthur Conan Doyle. From an early age she had to work to support herself. 

Throughout her life, Yvonne developed her mediumship and devoted herself to psychographing doctrinal and spiritual works. Her messages conveyed teachings of love, peace and spiritual evolution, and she was highly respected in the spiritist milieu. Yvonne was also the author of several books, in which she recounted her mediumistic experiences and shared her knowledge of the afterlife. 

As we have already seen, her mediumnity appeared in the first days of his earthly life, through the phenomenon of catalepsy, which became a regular phenomenon in her life from the age of 16. 

Most of the afterlife stories, novels, chronicles and tales told by Yvonne Pereira were collected in the Spirit World through this process, at the time of the restorative sleep. She wrote one of the greatest works of mediumship, Memoirs of a Suicide, considered a bestseller, with a special content, revealing in a truthful way the Spiritual Life of those who in the afterlife realise the grave error they have committed, suicide, in the delirious desire to free themselves from the evils or discomforts of existence. 

Her mediumship, however, was diverse. She was a psychographic medium and prescriber (homeopathy) assisted by entities of great elevation, such as the aforementioned Bezerra de Menezes, Charles, Roberto de Canalejas and Bittencourt Sampaio. He practised incorporation and passive mediumship. He had mediumnity of physical effects, and even carried out some materialisation séances, but he was never attracted to this mediumistic modality. His preferred séances were those of unfoldment, incorporation and prescriptions. Yvonne Pereira has always followed the guidelines of the basic books of the Codification and also the advice of her guides. Among her incarnated mentors, the outstanding spiritist of Barra Mansa, Zico Horta, who instructed her in the beginning of her mediumship, stands out. And it was through this work, carried out without interruption, that she practised prescriptions and healing passes for 54 and a half years. 

Yvonne Pereira worked as a medium from 1926 until 1980, when a stroke prevented her from practising her profession. Always humble, tender and vivacious, she lived in a large house in Piedade, a suburb of Rio de Janeiro, in the company of her married sister, Amália Pereira Lourenço, also a spiritist. On the night of 9 March 1984, she died of thrombosis during a surgical operation she had undergone at the Lagoa Hospital in Rio de Janeiro. Her body was buried in the Inhaúma cemetery. She was 83 years old and remained single, worthily fulfilling the mediumistic mandate she had exercised with love and total dedication to her fellow men.
