Pehr Wilhelm Wargentin

Pehr Wilhelm Wargentin (Sunne parish, Jämtlands län 11 September 1717 (OS) – Stockholm 13 December 1783), Swedish astronomer and demographer.

According to his own account, Wargentin was unimpressed with the purely classical and theological curriculum and the lack of any education in the sciences and did not finish the fourth year.

In 1756 Wargentin married Christina Magdalena Raab, a marriage that would produce three daughters until his wife's death due to a miscarriage in 1769.

[3] Wargentin made studies on the moons of Jupiter and published his first paper on the topic in 1741 in the Acta of the Royal Society of Sciences in Uppsala.

Wargentin was assigned to lead this task nationally in 1754, and subsequently published a number of demographic articles in the Transactions of the Swedish Royal Academy, in particular “Mortaliteten i Sverige, i anledning af Tabell-Verket”.
