A groundbreaking biography of Aino Sibelius suggests she was tough, inside and out.
Aino would give her husband the silent treatment for weeks on end and order him to write symphonies, not short pieces.
She would lock various of her six children in a cupboard if they misbehaved.
Her daughter Ruth Sibelius said: ‘She had a very strong character, and such people do not always fully understand others. The weak ones.’
Aino died in 1969, aged 97.
