Leonid Mezheritski was born on December 11, 1930, and spent most of his life in the cosmopolitan city of Odessa, whose streets and suburbs are found in many of his works.

After the fall of the Iron Curtain, also to Italy, Germany and Israel, where in the north of the country, in Upper Galilee, he lived and worked for the last eight years of his life.

He graduated from Odessa State Art School in 1955, class of Dina Frumina and worked mainly in the medium of oil, in his own picturesque manner, based on the coloristic nature of Impressionism and Post-Impressionism.

Loyal to the tradition of Odessa Impressionism, in which the French Impressionist treatment of light and form has been adapted to the uniquely atmospheric color palette of Odessa's silvery ash winters, warmly saturated flowering summers, and historic seaside landscapes and architecture, Mezheritski's bold, focused activity and confident, gestural handling of paint always verged on abstraction.

The narrative-thematic paintings,[3] created in the 1960s – 1970s on the orders of the Soviet Art Fund in realistic style can be found in current directories of galleries across Ukraine and Russia.
