"Georg Friedrich Grotefend (9 June 1775 – 15 December 1853) was a German epigraphist and philologist. He is known mostly for his contributions toward the decipherment of cuneiform.
Georg Friedrich Grotefend had a son, named Carl Ludwig Grotefend, who played a key role in the decipherment of the Indian Kharoshthi script on the coinage of the Indo-Greek kings, around the same time as James Prinsep, publishing Die unbekannte Schrift der Baktrischen Münzen ("The unknown script of the Bactrian coins") in 1836." - (en.wikipedia.org 11.08.2021)
