A brief article in The Great Soviet Encyclopaedia says he was born on May 8, 1907, in the town of Yefremov or Efremov (Russian: Ефре́мов) in the Tula Oblast.

[1] In 1945, Ivanov succeeded Nathan Rakhlin as Principal Conductor of the USSR State Symphony Orchestra.

[2] Konstantin Ivanov was succeeded as Principal Conductor of the USSR Symphony Orchestra in 1965 by Yevgeny Svetlanov.

His reputation in later years, at least in the west, was somewhat eclipsed by the rise of a younger generation of Soviet conductors such as Svetlanov, Rozhdestvensky and Kondrashin, all of whom became much better known, and who travelled abroad more frequently.

[3] Some of Ivanov's recordings became available in the west through the association of Britain's EMI Group with the Soviet state label Melodiya.

EMI-Melodiya used these as fillers on LPs of Tchaikovsky’s First and Third Symphonies, conducted by Ivanov's successor Yevgeny Svetlanov.

In 1973 Melodiya issued an LP of Rimsky-Korsakov's suites from Le Coq d'Or and Tsar Sultan.

The Symphony was also released on Dutch Melodia LP 562.265 with Liadov's Kikimora, Baba Yaga and two orchestral polonaises.
