Gustaf Fredrik Gyllenborg

Count Gustaf Fredrik Gyllenborg (25 November 1731 – 30 March 1808) was a Swedish writer.

Gustaf Fredrik Gyllenborg was born in Suinstad, Östergötland and died in Stockholm.

He was one of the leading lights of Tankebyggarorden (Order of the Thought-builders), one of the earliest literary societies, which was founded by Carl Fredrik Eckleff.

From 1756 to 1762 he stayed as a cavalier of the heir to the throne Gustav at the Swedish royal court.

In order to introduce him to the state civil servant career, he was elected bank representative, and was a member of the number lottery.
