Johannes Bilberg

Johannes Bilberg (17 November 1646 – 11 March 1717) was a Swedish theologian, professor and bishop.

He was the son of school principal and vicar Jonas Amberni and his wife Ingrid Denckert. he took employment as a tutor for a young baron named Ulf Bonde on a trip around the continent of Europe when they visited royal courts and universities.

At this time a controversy had erupted between the new Cartesian philosophy and the theological orthodoxy in Uppsala. Priests at the Riksdag were also involved in the debate, which made the government feel compelled to set up a special commission to investigate the matter. The expedition, dedicated to Karl as "sun-king", observed that the sun could indeed be observed around the clock at high altitudes. Bilberg afterwards published a work in Latin and Swedish under the title of Refractio solis inoccidui, in septemtrionalibus oris (About the refraction of the midnight sun, in the Northlands). The couple had four children together. All four were knighted by Karl XII in Bender at which time they were entitled to retain their father's last name of Bilberg.

In 1701, Bilberg was named bishop of Strängnäs after Erik Benzelius resigned to become archbishop. He continued as bishop in that congregation until his death in 1717.
