University as bookkeeper (räntmästare). His son, Lars Johan Hierta, born in 1801,
became an important liberal politician, newspaper editor, book publisher and
businessman. The newspaper he founded, Aftonbladet (Evening Post), is still one of
the major Swedish tabloids.
11.4.21 Carl Gustaf Robsahm
Robsahm [62] was born in 1752. The Robsahm family had been involved in mining
and iron production since the seventeenth century, [63] and a mining exam was a
natural step in the career of Carl Gustaf. He defended a thesis on the analysis of
asbestos, de terra asbestina (Sect. 25.6) in 1782. He went on to become bookkeeper
at Letafors iron works near Torsby in the Värmland province. He died in 1821.
11.4.22 Fredrik Wilhelm Mannercrantz
Mannercrantz [64] was born in 1755 and studied pharmacy in Stockholm and
Strängnäs before enrolling at Uppsala University. In 1782 he defended his thesis de
antimonialibus sulphuratis and obtained a bachelor degree in medicine the same
year. He practised a few years as physician in Strömstad before buying the pharmacy in Enköping and taking his apothecary exam in 1785. In 1792 he opened a
pharmacy in Sigtuna [65]. He died in 1796. By 1782, Bergman’s health started to
decline, and Mannercrantz became the last student to present a thesis under
Bergman’s supervision.
