The first noted use of “serendipity” in the English language was by Horace Walpole (1717–1797). In a letter to Horace Mann (dated 28 January 1754) he said he formed it from the Persian fairy tale The Three Princes of Serendip, whose heroes “were always making discoveries, by accidents and sagacity, of things they were not in quest of”.
