Hammad was born in 1923 in Damascus , Syria . He studied art at the Accademia di belle arti di Roma between 1953 and 1957. He focused on the art of engraving and especially the art medals. After completing his studies he returned to Damascus in 1960 and taught as professor at the Fine Arts Faculty of Damascus since its creation. From 1970 until 1980, he became dean at the Fine Arts Faculty of Damascus. In 1939, he started exhibiting his work throughout most Arab countries, Europe and the United States. In 1948, he received first prize in Arts in Damascus Exhibition, in 1957, first prize at the competition of the city of Naples, and in 1959, first prize at the competition of the Ministry of Culture in the United Arab Republic. In his work, Hammad uses the geometry of elementary forms to express the dynamic spirit of the Arabic letter. Among circles, squares, rectangles, determined by the color, the letter appears with freedom to end a profound silence. His work has been shown in exhibitions at museums such as the Jordan National Gallery of Fine Arts .
