Kuzma Sergeevich Petrov-Vodkin was a Russian/Soviet painter. His early iconographic work used special creative effects based on the curve of the globe, but its images were considered blasphemous by the Russian Orthodox Church. However he went on to become the first president of the Leningrad Union of Soviet Artists. His autobiographical writings attracted much praise, and have enjoyed a later revival.

Kuzma Petrov-Vodkin was born in Khvalynsk (Saratov Oblast) into the family of a local shoemaker. His first exposure to art was in his early childhood, when he took some lessons from a couple of icon painters and a signmaker. Still, Petrov-Vodkin didn't quite see himself in art at that time; after graduating from middle school, he took a summer job at a small shipyard with plans to get into railroad college in Samara. After failing his exam, he turned to "Art Classes of Fedor Burov" in 1896

In April 1895, Burov died and for some time Petrov-Vodkin took different painting jobs in the vicinity of Saratov. By chance, his mother's employer invited a well-known architect, Robert Meltzer (ru). Petrov-Vodkin was introduced to the guest and impressed him enough to get an invitation to study art at Saint Petersburg. The education was financed by a charitable subscription among local merchants. He also met at this time Victor Borisov-Musatov, an important painter resident in Saratov, who encouraged Petrov-Vodkin to continue his studies.

Petrov-Vodkin stayed in Saint Petersburg from 1895 to 1897 studying at the Stieglitz Academy, before moving to the Moscow School of Painting, Sculpture and Architecture. There Petrov-Vodkin was a student of Valentin Serov, Isaak Levitan, and especially Konstantin Korovin. In 1901 he travelled to Munich to take classes with Anton Ažbe.

While in Paris in 1906 he met and married Maria Jovanovic (1885–1960), a daughter of Serbian immigrant hotel-keepers. She remained his lifelong companion. They had two daughters, one of whom died [unverified] in childhood.

Even during his college years, Petrov-Vodkin managed to enter into conflict with the Russian Orthodox Church, which discarded his work on a chapel in Samara and ultimately destroyed it as unacceptable. A number of his early works were deemed too erotic. His first well-known work was The Dream (1910), which sparked a discussion among contemporary Russian artists. The main defender of the painting was Alexandre Benois; his main detractor was Ilya Repin (hence, Petrov-Vodkin was discussed by two of the major Russian painters of the time). Other major works of that time include Boys at play, and, notably, Bathing of a Red Horse, (1912) his most iconic work - a symbol of the coming social changes. The latter became an instant classic, and, in a sense, trademark for the artist.

During this stage in his artistic development, Petrov-Vodkin extensively used an aesthetic of Orthodox icon together with brighter colours and unusual compositions. His works were often deemed blasphemous and erotic.

From 1924 to 1926 Petrov-Vodkin lived in France with his family. In 1922 he painted a portrait of the Russian poet Anna Akhmatova.

During his earlier years, Petrov-Vodkin developed his "spherical perspective": a unique twist that distorted the drawing as to represent the viewer high enough to actually notice the spherical curve of the globe.

He used it extensively through his works like Death of a Commissar and In the Line of Fire, which make the observer seem more distant, but actually close. It is argued that this twist has been built upon Byzantine perspective - an inverted perspective used in iconography.

Petrov-Vodkin used darker tones with time, but his paintings became more detailed. He started painting still life and portraits, stepping further away from his previous themes.

With help from the Soviet government, he made several trips across the Soviet Union, producing many works with didactic purposes.

In 1927, Petrov-Vodkin contracted pulmonary tuberculosis and had to curtail painting for several years. He turned to literature and wrote three major semi-autobiographical volumes, Khlynovsk, Euclid's Space and Samarkandia. The first two of these are considered on a par with the finest Russian literature of the time.

In the spring of 1932 the Central Committee of the Communist Party decreed that all existing literary and artistic groups and organizations should be disbanded and replaced with unified associations of creative professions. Accordingly, the Leningrad Union of Artists was established on 2 August 1932, which brought the history of post-revolutionary art to a close. The epoch of Soviet art began. Petrov-Vodkin was elected the first president of the Leningrad Union of Artists in 1932.

Petrov-Vodkin's other important pieces during this period include 1919. Alarm. (1934).

In February 1939, Petrov-Vodkin died of tuberculosis in Leningrad.
