Most of the biographical data on Eugène Ionesco cannot be exactly determined for the beginnings of his career. When asked Eugène Ionesco pointed out that this would be personal data, only of interest for himself (and unfortunately the police – direct quote Ionesco). For the knowledge of his literary works, Ionesco says, the reading of his “Diaries” would be sufficient.
1909: Ionesco was born on November 26 (November 13 according to orthodox calendar) in Slatina (Romania). The often mentioned year of birth 1912 was given by Ionesco in Paris since being a newcomer to the theatre scene he wanted to be among the youngest.
1913-1925: Ionesco lives in France with his mother, mostly in Paris.
1916: Ionesco’s father returns to Romania, which has just entered into war. In his youth Ionesco regularly (each Thursday) watches the puppet theatre in "Jardin du Luxembourg".
1917: Ionesco’s father, who at first was believed to have been killed in war, marries again. The father always took Power’s side, no matter what colour. Last but not least for this reason the relationship between Ionesco and his father was permanently tense.
1917-1919: Because of his poor health Ionesco’s mother sends him to La Chapelle Anthenaise together with his sister Marilina (born 1911). In his diaries Ionesco describes this period as the most peaceful and harmonic time of his life.

In answering the questions whether he was refering to "the king dies" Ionesco replied: "I refer to all of my plays" (Quelle Biographie Rowohlt Verlag). In Paris Ionesco develops a liking in the works of Emmanuel Mounier, Berdiaev, Jacques Maritain and Gabriel Marcel.
