From 1900-1902 he became a pupil of Archip Kuindzhi in St. Petersburg, and from 1902-1904 he attended the studio of the Hungarian Professor Simon Hollocy.
Beginning in 1920 Kaigorodov lived and worked in Tallinn, Estonia, becoming a member of the Art Society K.T.E.U.
He both sent his pictures to, and held exhibitions in, Germany (Glaspalast Munich), Berlin and Karlsruhe, the Netherlands (Den Haag) and England (London).
Several dozens of his paintings were left behind in Poznan in January 1945 and these occasionally surface on the international art market.
Kagorodov was mainly a landscape painter within the Russian tradition, but he also produced a number of genre paintings and portraits.
