Habibollah Sadeghi belongs to the generation of "revolution artists." This outstanding painter was born in Tehran. The sparks of his interest and talent in painting were lit from the age of eight. He started learning painting at Tehran Fine Arts Academy between 1973 and 1975. Then he went to the Tehran College of Fine Arts to continue his studies and graduated in 1983 with a bachelor's degree in painting. During this period, he studied under the supervision of professors such as Mehdi Hosseini, Hannibal Alkhas, Mahmoud Farshchian, Parviz Tanavoli, Marco Gregorian, etc. Later, he went to Tarbiat Modares University and received a master's degree in painting and a doctorate in art research. Sadeghi began his artistic activity amid the 1979 revolution, mainly with political and social satire in the press, and during the following years, he focused more and more on painting.
Along with artists such as Kazem Chalipa and Naser Pelangi, he was among the core revolution artists movement. The works of this famous artist have been displayed many times in different countries, such as the United States, Canada, Poland, France, Germany, Italy, China, etc. His works were selected in the first, second, and fourth contemporary Iranian painting biennial. He also won the "Chosen Artist" title in international events such as the Japan International Fine Arts Competition in 1370 and the Netherlands International Design Competition in 1993.
Sadeghi is one of the visual art centers of the Hozeh Honari's founders  (Islamic Advertising Organization) and has had many responsibilities. Among them, we can mention membership in the Art Committee of the Supreme Council of Cultural Revolution, membership in the Art Academy, and supervision of the Tehran Museum of Contemporary Arts between 2006 and 2008. He also taught as a painting teacher for many years at Tehran Fine Arts College and Shahed University.
Sadeghi, believing that "art is discovery, intuition, has an inner meaning," has been following a type of allegorical painting in religious and mystical themes since the early 1980s. Flying figures in the rhythm of twisted lines and the combination of moderate paints are most of his works' characteristics. Habibollah Sadeghi died in Tehran in August 2022 due to a heart attack.
