Biographie

Thomas de Hartmann was born in Khoruzhivka, Poltava Governorate, Russian Empire, now Sumy Oblast, Ukraine. At the age of 18 he received his diploma from the Saint Petersburg Conservatory. He studied conducting in Munich with Felix Mottl before World War I.

Thomas de Hartmann was a graduate of the Imperial Conservatory of Music. He studied musical composition with three of the greatest Russian composers of the 19th century: Nikolai Rimsky-Korsakov, Anton Arensky and Sergei Taneyev. His piano teacher was Anna Yesipova, the second wife and former student of Theodor Leschetizky. Most of de Hartmann's compositions were for voice and piano. In 1907, his ballet The Pink Flower, produced by Sergei Diaghilev with Vaslav Nijinsky and Tamara Karsavina in the cast, was presented at the Imperial Opera. The Tsar was so impressed that he himself granted de Hartmann exemption from military duty so that he might study conducting in Munich.

In Munich, Thomas de Hartmann met the artist, former Sufi student and later stage impresario, Alexander de Salzmann; they were both friends of Rainer Maria Rilke and Wassily Kandinsky. Later, in Russia, after the beginning of World War I, de Hartmann would introduce de Salzmann to George Gurdjieff.

Thomas married Olga Arkadievna de Schumacher, a celebrated opera singer; her father was a high official in tsarist Russia.

Thomas was the nephew of Eduard von Hartmann, the author of Philosophy of the Unconscious, a book published in Germany in 1869 but well known in America and England.
