Ardeshir Mohasses (also romanized Ardešir Moḥaṣṣeṣṣ, Ardashir Mohases, Persian: ردشير محصص) was born September 9, 1938 in Rasht, Iran. One of four children, and cousin to the noted artist Bahman Mohasses, he was raised in Lahijan. Ardeshir Mohasses began his career as an illustrator as a student in the 1950s, contributing work to Towfiq, a satirical publication. Although he applied to and was accepted by the University of Tehran's Faculty of Fine Arts, he opted to study political science and never trained formally as an artist. After graduating university in 1962, he briefly worked as a civil servant before deciding to pursue art full time. His work appeared in Iranian publications including Ketāb-e hafta and Kayhān, cementing his reputation as a leading illustrator and pioneer of satirical cartoons in Iran by the late 1960s. He published several volumes of work through the 1970s.
By the 1970s, Mohasses gained increasing recognition internationally, leading to publication of his work in major outlets in the United States, Europe, and Asia. He also exhibited works and toured in the United States. Facing hostility from the government of Shah Mohammed Reza Pahlavi, Mohasses relocated to New York City in 1976 and decided to remain following the 1979 Iranian Revolution. He continued working, satirizing and criticizing the new Iranian government as he had the old.
Mohasses' health declined following a Parkinson's disease diagnosis in 1986 and other challenges. He continued publishing, including Ardeshir Mohassess: Closed Circuit History (1989) and Life in Iran: The Library of Congress Drawings (1994). He remained active until his death in New York on October 9, 2008. His life and legacy were celebrated at the conference "Ardeshir Mohassess, Art, Politics, and Beyond" at New York University, October 9-10, 2010, as well as Ardeshir: The Rebellious Artist by Bahman Maghsoudlou, a revised version of a documentary originally released in 1972 as Ardeshir Mohasses and His Caricatures.
