Calligraphist (B. 1770, Istanbul, D. 23rd June 1849, Istanbul). His full name was Yesarizâde Mustafa İzzet Efendi. He was the son of Yesari Mehmed Esad, the pioneer of Turkish nastalīq. He was named as “Yesari” because he was writing very aesthetically with his left arm because of the disability of his right arm. Later, his family used this name. İzzet Efendi was trained by his father and received the permission from calligraphist Osman el-Üveysi Efendi (1789). Besides, he had a third diploma which had one thousand pages and was approved by five calligraphists.
Mustafa İzzet was a kazasker (T.N. military judge) of Anatolia in 1839 and was appointed to Takvimhane-i Âmire (T.N. the Imperial Printing House) in 1842. He created his own letters of Nastalīq and printed his first book with them. In 1846, he was appointed as the kazasker of Rumelia. Upon his death, he was buried in Fatih, next to his father’s grave.
Mustafa İzzet, who gained fame in his young ages, used his father’s style in his writings at first. After his father’s death, he established his own style by imposing his understandings into Nastalīq in the 1800s. He composed his best works after 1844. Most of the calligraphy on buildings constructed during the reign of Mahmud II belonged to him. Epigraphs of Nusteriye Mosque and Public Fountain, Mausoleum of Mahmud II, Gates of Sublime Porte (T.N. house of government of the Ottoman Empire), Alay Mansion, Hidayet Mosque are one of those. His most famous students were Kıbrısîzade İsmail Hakkı Efendi (1785-1862), Ali Haydar Bey (1802-70), Kazasker Mustafa İzzet and Abdülfettah Efendi (1815-96).
