Background
He was born in Vågå, the son of Tjøstolv Olsson Kleppe of Sygaard (a well-known rabble-rouser, also called "Galin-Tjøstolv", who died in 1797) and Marit Pedersdotter (died 1803) from Horgje in Heidal.
He was born in Vågå, the son of Tjøstolv Olsson Kleppe of Sygaard (a well-known rabble-rouser, also called "Galin-Tjøstolv", who died in 1797) and Marit Pedersdotter (died 1803) from Horgje in Heidal.
He is believed to have been the model for Henrik Ibsen’s Peer Gynt. He had four siblings. He was well known for reindeer hunting and sharpshooting in the Jotunheim mountains, and built many cabins or huts at Lake Gjende.
He moved there in 1842.
In 1850 he bought the mountain farm Brurusten in Murudal from Jakob Kleiven. He took the name John Gjendin, and shortened it to Jo Gjende in his later days.
Occupied by natural philosophy, he participated frequently in discussions with the local minister. As a result he was recognized as a freethinker.
He died on the Brurusten farm in Murudal, and was buried in Vågå churchyard.
On his grave is a small soapstone monument, which shows a wild reindeer herd in flight, after a painting by Gerhard Munthe.
