Maimon was born in Vilkaviškis, in the Augustów Governorate of Congress Poland (present-day Lithuania).

In later years he was a member of the "Society for the Encouragement of Jewish Arts", which was established in St. Peterburg in 1916.

Among his familiar works are: "The Marranos", "The Hashmonaim", "The Inquisition" (1893), "Back in the Homeland", "After the Pogrom" (at the Israel Museum Collection, Jerusalem), "The Battle in the Mountains of Turenchin" (1906) and series of paintings devoted to biblical figures.

Maimon's painting "The Marranos" was long believed lost by several scholars, including Gabriella Safran, Olga Litvak, and Hillel Kazovsky.

But an article by Musya Glants at Harvard tells the exciting and amusing story of the painting's adventures and discovery and eventual "safe harbor".
