Born in Nizhny Novgorod to a family of the staroobryadtsy merchants, Serafim Golovastikov debuted on stage the Nizhny Drama Theatre in the late 1880s, where he adopted the stage name Sudbinin. In May 1898 Sudbinin joined the Stanislavski-led Moscow Art Theatre's original troupe and took part in its very first production, Tsar Fyodor Ioannovich. In the course of the next several years he took part in all this company's major productions, including Men Above the Law, Antigona, The Death of Ivan the Terrible, Twelfth Night, Snow Maiden, The Philistines, The Power of Darkness. He was a substitute for Stanislavsky as Vershinin in Chekhov's The Three Sisters, as well as Satin in The Lower Depths. In the early 1900s Sudbinin became increasingly interested in sculpture, painting and photography. His first major work was the statuette of Stanislavsky as Doctor Stockman. Sudbinin gave it as a souvenir to Maxim Gorky, and it is now exposed at the Gorky Museum in Nizhny. After visiting Paris in 1904, Sudbinin decided to devote himself to sculpture. A grant awarded by Savva Morozov enabled him to study sculpture under Leopold Sinaeff-Bernstein and Auguste Rodin, which he would later become an assistant of. After exhibiting a series of Sleeping Monsters at the Salon dAutomne, he became a member of the Union of Russian Artists and Salon d'Automne. His best-known sculptures include "Sisyphus", "Cherubini at Rest", "Maxim Gorky", "Anna Pavlova", "Fyodor Chalyapin", "Chalyapin as Romeo", "Skryabin" and "Leonid Sobinov". His exhibitions, at the Moscow Fellowship of Artists, Salon d'Automne, Salon de la Nationale, Sergei Makovsky Salon, Union of Russian Artists, Les Ballets Russes de Serge Diaghilev in Paris, international exhibitions in Venice, Munich and Rome and the exhibitions of Russian art in Paris, Venice, London, New York City, Belgrade and Prague, as well as one-man shows in New York, Paris and San Francisco, won him much critical acclaim. After the October Revolution Sudbinin left Soviet Russia for Paris. He visited the United States, where he created ceramic vases and animal figurines. In an air raid during World War II, his Paris studio was destroyed. Serafim Sudbinin died on November 1, 1944, in Paris.
