Alexander Sergeievich Taneyev

Russian composer (St. Petersburg, 1850-1918)
(Not to be confused with the distantly related, more famous composer Sergey Ivanovich Taneyev (1856-1915)).
After studying at St. Petersburg University, Alexander Sergeievich undertook musical studies in Dresden and with Rimsky-Korsakov in St. Petersburg. He was a close friend of the group of composers known as the "Mighty Handful", especially of Mussorgsky and Balakirev (the latter wrote orchestral versions of two waltzes by Taneyev), and took a keen interest in the national development of Russian music.
Though he composed only sporadically -- his duties as a bureaucrat prohibited him much time out of his office -- he managed to compose two operas, three symphonies, three string quartets, as well as other chamber music, choral pieces and songs. Almost all of his pieces were performed during his lifetime.
