Legitimised son of Emperor Pedro I of Brazil and Henriette Joséphine Clémence de Saisset. As soon as Pedro was born, his father hastened to assure Henriette de Saisset that, despite circumstances preventing him from recognising his son, he would never abandon him financially and that he would provide the means for his existence and education (in a message to the child's mother, dated November 1829). But the promise was not kept. From April 7, 1831 on, the situation of the Frenchwoman and the boy began to be affected by the abdication of Pedro I to the Brazilian throne. A little later, he moved to Portugal, where he began a long battle against his absolutist brother Miguel, to guarantee the throne of Portugal to his daughter Maria, who had become entitled to the throne at the age of seven. The death of Pedro I, on September 24, 1834, was a blow to Henriette de Saisset. The main fear, expressed in a letter to Francisco Gomes da Silva, dated December, was that the son would no longer receive the financial help promised by his biological father. The Frenchwoman did not take her son to the funeral ceremonies, but made him mourn. "Once, however, they dressed me all in black, telling me that my Friend was dead. I didn't know who the one I had just lost was", recalls Pedro de Saisset, in a letter to his half-brother Emperor Pedro II of Brazil, three decades later. While he lived in Paris, the first Emperor of Brazil received visits from his son, but he never revealed that he was his father. Little Pedro was five years old when he lost the mysterious friend, who would put him on his knees and give him candy. Saisset was very affectionate and kept in touch with his half-sister, Princess Januária, Countess of Aquila, whom he would mourn for five months in 1901. The Emperor ended recognising him as his son in his will and gave him a part of his inheritance. Pedro de Saisset worked on a variety of business ventures in the United States, where he served as a consular agent for France for more than three decades. He married Maria de Jesus "Jesusita" Palomares de Suñol and had four children: Henriette, Ernest, Pierre and Isabel.
