Anatoly Konstantinovich Lyadov or Liadov (Russian: Анато́лий Константи́нович Ля́дов; May 12 [O.S. April 30] 1855 – August 28 [O.S. August 15] 1914) was a Russian composer, teacher and conductor.
Lyadov was born in St. Petersburg into a family of eminent Russian musicians. He was taught informally by his conductor step-father Konstantin Lyadov from 1860 to 1868, and then in 1870 entered the St. Petersburg Conservatory to study piano and violin.
He soon gave up instrumental study to concentrate on counterpoint and fugue, although he remained a fine pianist. His natural musical talent was highly thought of by, among others, Modest Mussorgsky, and during the 1870s he became associated with the group of composers known as The Mighty Handful. He entered the composition classes of Nikolai Rimsky-Korsakov, but was expelled for absenteeism in 1876. In 1878 he was readmitted to these classes to help him complete his graduation composition.
He taught at the St. Petersburg Conservatory from 1878, his pupils including Sergei Prokofiev, Nikolai Myaskovsky, Mikhail Gnesin, Lazare Saminsky and Boris Asafyev. See: List of music students by teacher: K to M#Anatoly Lyadov. Consistent with his character, he was a variable but at times brilliant instructor. Conductor Nikolai Malko, who studied harmony with him at the conservatory, wrote, "Lyadov's critical comments were always precise, clear, understandable, constructive, and brief.... And it was done indolently, without haste, sometimes seemingly disdainfully. He could suddenly stop in midword, take out a small scissors from his pocket and start doing something with his fingernail, while we all waited."
