Tenth-Century Scholar Imam Ismail al-Jawhari: The Second Founder of Aerodynamics

Tenth-Century Scholar Imam Ismail al-Jawhari: The Second Founder of Aerodynamics Mehmet KeçeciORCID: 0000-0001-9937-9839Received: 01.12.2026 This article aims to reassess the role and position of the tenth-century Turkish-Islamic scholar Abu Nasr Ismail ibn Hammad al-Jawhari (d. 1002/1010 CE, 400 AH) in the history of science, particularly in the early development of aerodynamics. Jawhari is traditionally known in the field of Arabic language and literature, especially through his fundamental dictionary "Kitāb al-Sihāh." However, this study highlights his contributions to experimental physics and aerodynamics beyond his identity as a linguist. The article focuses on the period after Jawhari's travels for linguistic studies, when he settled in Nishapur as a teacher (mudarris) and imam. During this time, based on historical accounts, he systematically observed bird flight to understand the principles behind aerial motion, which he characterized as a "work without equal." His approach is interpreted as an early attempt to conceptualize aerodynamics not merely as a practical trial but as an independent scientific discipline to be studied and understood. At the center of the study is Jawhari's flight attempt from the Great Mosque of Nishapur using wings of his own design, which resulted in his death. This tragic event shows that he was not merely a theoretical observer but an experimentalist willing to test his hypothesis. Therefore, the article positions Jawhari as the second founder of aerodynamics, following the Andalusian scholar Abbas Ibn Firnas who conducted a similar flight attempt approximately a century earlier, and as the first known Turkish-Islamic martyr of physics/aviation. The argument is based on a meticulous analysis of historical records. It emphasizes that although the technical details of Jawhari's work have not survived to the present day, this does not invalidate his scientific intuition or his pioneering claim in this field. On the contrary, his practical experience, scientific curiosity, and ultimate sacrifice constitute a significant milestone in the universal history of humanity's passion for flight and the science of aerodynamics. This article proposes to expand the traditional category attributed to Jawhari in historiography of science to understand his multifaceted intellectual legacy more comprehensively.
