Alexander Alyabyev

He wrote seven operas, twenty musical comedies, a symphony, three string quartets, more than 200 songs, and many other pieces.

The colonel died a few days later, possibly from a ruptured spleen, and Alyabyev was arrested on a charge of murder.

While the evidence was not conclusive, Tsar Nicholas I expressly ordered him into exile to his native town of Tobolsk.

[1] Alyabyev's most famous work is The Nightingale (Соловей), a song based on a poem by Anton Delvig.

The song became more widely known after having been introduced into Rosina's singing lesson scene in Gioachino Rossini's The Barber of Seville by Pauline Viardot, followed by Adelina Patti and Marcella Sembrich.
