Richard Nikolaus Eijiro, Count of Coudenhove-Kalergi (16 November 1894 – 27 July 1972), was a politician, philosopher, and count of Coudenhove-Kalergi. A pioneer of European integration, he served as the founding president of the Paneuropean Union for 49 years. His parents were Heinrich von Coudenhove-Kalergi, an Austro-Hungarian diplomat, and Mitsuko Aoyama, the daughter of an oil merchant, antiques-dealer and major landowner in Tokyo. His childhood name in Japan was Eijiro Aoyama (青山 栄次郎). Being a native Austrian-Hungarian citizen, he became a Czechoslovak citizen in 1919 and then took French citizenship from 1939 until his death.

His first book, Pan-Europa, was published in 1923 and contained a membership form for the Pan-Europa movement, which held its first Congress in 1926 in Vienna. In 1927, Aristide Briand was elected honorary president of the Pan-Europa movement. Public figures who attended Pan-Europa congresses included Albert Einstein, Thomas Mann and Sigmund Freud.

Mitsuko Thekla Maria, Countess of Coudenhove-Kalergi (German: Mitsuko Thekla Maria Gräfin von Coudenhove-Kalergi, born Mitsuko Aoyama (青山光子); 7 July 1874 – 27 August 1941) was one of the first Japanese people to immigrate to Europe, after becoming the wife of an Austro-Hungarian diplomat, Heinrich von Coudenhove-Kalergi, in Tokyo. She was the mother of Richard von Coudenhove-Kalergi and the Catholic author Ida Friederike Görres (née von Coudenhove-Kalergi).
