Johan David Ǻkerblad (1763-1819), Swedish orientalist and interpreter in the Swedish diplomatic service who then switched to philological research, settling in Rome in 1809. Speaking fluently Greek, Turkish, Arabic and Persian, he worked on deciphering the Rosetta Stone in 1801-02 while posted to Paris. Nevertheless his scholarly output was small. He died alone, neglected by Sweden, and his tomb was raised by the Prussian legation five years after his death.
