This paper deals with the efforts of scientist Fuat Sezgin in reviving the Arab heritage. What motivated him to study Arab heritage? How was his scientific personality affected by that study? How did he move from the stage of collecting the history of the Arab scientific heritage to the stage of investing in the renaissance of the Muslim nation in the contemporary time? We will discuss the merger between the results of the Islamic heritage and the scientific personality of Sezgin, and the influence of Sezgin on the products of that heritage as the leading scientist in this field. The research will discuss the influence of Sezgin on the scientists of his time, and how Sezgin moved from the collection of Islamic heritage to the stage of awareness and defense of this heritage. This is an overview of the research that we will discuss here.
