In 1903 to 1904 he studied art in the studios of Konstantin Yuon and Ilya Mashkov, in 1905 to 1909 he studied at the Moscow School of Painting, Sculpture and Architecture with Konstantin Korovin and Valentin Serov.

In 1910, Falk was one of the founders and the most active participant of the artistic group Jack of Diamonds.

[2] The group considered Paul Cézanne the only painter worth following, and the rest of visual art to be too trivial and bourgeois.

In 1918-1928, Falk taught at VKhUTEMAS (State Higher Artistic and Technical Workshops).

His works of that time were in neo-impressionist style with characteristic white-on-white colors (not unlike the later paintings of his teacher Valentin Serov).
