Russian agriculturist (b. 1833; d. 1882), born German Karlovich Konradi (Герман Карлович Конради), also known as Herman Conradi.
By his marriage to Alina Meyer (1849–1932), Herman had a deaf-mute son Nikolay (1868–1922) to whom the composer's brother Modest Tchaikovsky became tutor in 1876. The composer and his brother often stayed at the Konradis' estate at Grankino, and knew the family well. Herman divorced Alina in 1881, and Modest was granted permanent guardianship of Nikolay the following year after Herman's death.
