Nahum Tschacbasov

[3] There are varying stories as to why he used different names either due to a forged passport used for immigration; to avoid paying child support; and/or because he was a con-man.

[3] Tschacbasov moved to France in 1932 to 1933, where he studied painting with Adolph Gottlieb, Marcel Gromaire, and Fernand Léger.

[3] In 1935, he was part of a group exhibition at the Gallery Secession alongside Mark Rothko, Gottlieb, and the other artist members of "The Ten".

[10][11] His notable art students include Fritzie Abadi,[12] James F. Walker,[13] and his future wife Irene Zevon.

[10] In 2013, he had a posthumous solo exhibition curated by Marina Kovalyov at the National Arts Club, as part of the 11th Annual Russian Heritage Month.
