At age 4, Sirikit attended the Kindergarten College at Rajini School (sometimes called the Queen’s College). She studied at the primary level. During that time the Pacific War was being fought; Bangkok was attacked many times, thus making travel unsafe. She then moved to Saint Francis Xavier Convent School, because it was near the palace. She studied there from her second year at the primary level to the secondary level.
In 1946, when the war ended, her father moved to the United Kingdom to work as the ambassador to the Court of St. James's, taking his family with him. At that time, Sirikit was 13 and had graduated to the secondary level. While staying in England she learned to play the piano and learned English and French. Because of her father's work as an ambassador, she and her family moved to various countries, includingDenmark and France. While living in France, she studied at a music academy in Paris.
Also while in France, Sirikit met King Bhumibol Adulyadej, who is distantly related to her, both being descendants of King Chulalongkorn(Rama V.). At that time, Bhumibol had ascended to the throne and was studying in Switzerland. Both Bhumibol and Sirikit (as well as a few other students) were staying at the Thai Royal Embassy in Paris. Sirikit accompanied the king as he visited various tourist attractions. Both Bhumibol and Sirikit found much in common and thus began a relationship.
