Constantin (Kostia) Térechkovitch was a Russian painter born near Moscow. He initially studied at the Moscow School of Painting, Sculpture and Architecture in 1917, but fled the country during the Russian Revolution. In Paris, he enrolled at the Académie de la Grande Chaumière and settled among the Russian community in Montparnasse, where he met Mikhail Larionov and Chaïm Soutine.

Influenced by Bonnard, he became associated with Roland Oudot, Maurice Brianchon, André Planson and Jules Cavaillès. As well as painting colourful landscapes, towns, and portraits, he worked on sets and costumes for a ballet in Monte Carlo in 1933, where he met his wife. After the Second World War, his interests extended to sport and horses, and he owned his own racing yard. He died in Monaco in 1978.
