Collegium Curiosorum
Collegium Curiosorum was founded in the Gustavianum building during the plague year of 1710, when the University was shut down. The initiative came from the University librarian, Eric Benzelius, Jr. Besides Harald Vallerius, his sons Johann and Göran took part, as did professors Johan Upmark, Per Elvius, Olof Rudbeck, Jr., and Lars Roberg. They exchanged letters with Christopher Polhammar (after his ennoblement in 1716, Polhem) and Emanuel Swedberg (after his ennoblement in 1719, Swedenborg). The meetings ceased in 1711, but the society was succeeded by the Bokwettsgillet (Society of Book Knowledge) in 1719, the Royal Society of Science in 1728, and the Royal Swedish Academy of Sciences in 1739.
