Sibelius (1865-1957) is an important part of Finnish national identity, famous for works such as Finlandia, Valse Triste, and his Violin Concerto.
The diaries offer insights into his private life, including his happy marriage, his hostility towards critics of his work, and his financial dealings. Up until now, only a few researchers had access to the diaries.
Sibelius was born into a Swedish-speaking family in H‹meenlinna in the Russian Grand Duchy of Finland. He was christened Johan Julius Christian Sibelius, but soon adopted the name of his French uncle Jean.
