Calling himself
Hadorph or
Hadorphius, after the farm on which he grew up, he began to study at
Uppsala University, where he was appointed secretary of the academy in 1660. He was then noticed for his strong interest in national antiquities by
Magnus Gabriel De la Gardie and Count Erik Lindschöld (1634-1690). In 1666, he received a part of the salary of the director-general of the Central Board of National Antiquities, and he was appointed to be its seventh assessor in 1667. In 1669, he was promoted to be the secretary of the National Archives. In the same year, he and
Elias Brenner joined de la Gardie on an excursion through de la Gardie's fiefs, and Johan Hadorph made drawings of all the ancient monuments the party encountered. He also had access to de la Gardie's extensive library and made a Swedish verse translation of the history of
Alexander the Great, which was published during 1672. In the same year, he joined King
Charles XI of Sweden on his
Eriksgata through central and southern Sweden during which he was obliged always to be present and explain all the ancient monuments and curiosities that caught the king's attention. He received the whole position and salary as director-general of the Central Board of National Antiquities in 1679, when his co-director professor
Olof Verelius was promoted to be the librarian of
Uppsala University. In 1692, the Central Board of National Antiquities was transferred to Stockholm to function as an archive of antiquities rather than a college, and Johan Hadorph became its director. He died in the capital on July 12, 1693. == Production ==
