Friedrich August Rosen (2 September 1805 in Hannover – 12 September 1837 in London) was a German Orientalist, brother of Georg Rosen and a close friend of Felix Mendelssohn Bartholdy.
He was briefly professor of oriental literature at the University of London and became secretary of the Royal Asiatic Society in 1831.
[1] His Rigvedae specimen, excerpts from the Rigveda based on manuscripts brought back from India by Colebrooke, were enthusiastically received by European academia as the first authentic evidence of the archaic Vedic Sanskrit language.
His most important work was an edition of the entire Rigveda, left incomplete at his premature death shortly after his 32nd birthday.
Rosen also produced the first English translation of the Kitab al-Jabr wa-l-Muqabala of al-Khwārizmī, in 1831.
