[1] His home in Gudhjem, built from two fishermen's cottages with a rocky garden in the rear, is named "Norresân" after the nearby harbour, Nørresand Havn, where he painted many of his works.
During this period, he studied at Harald Giersing's school where Karl Isakson introduced him to Expressionism, especially through the work of Cézanne and Van Gogh.
[4] Inspired above all by Cézanne, Høst's work was also strongly influenced by the Nordic tradition as a result of the changing seasons and weather.
[3][5][6] Høst commented:[5] "We have our seasons, the long light nights, the enchantment that we must struggle with, while Cézanne lived in a place where there was no weather as such, as it was always the same.
They were sociable hosts, inviting many contemporary intellectuals to their home, including the author Otto Gelsted (1888–1968) who was a frequent guest.
[7] In 1943, Ole, the older of his two sons who had joined the SS, died in Barvinkove (Barwenkowo), a small town on the Eastern Front in Russia.
Høst felt guilty for the rest of his life about introducing his son to his friend Fritz Waschnitius, an Austrian-born translator and writer who was a Nazi supporter.
[8] Høst is also known for his subtly expressed acerbic views in the 1,800 diaries he called "log books", written with such clarity and self-criticism.
His family and friends thought that the term of 50 years on the log books may have been set because they contained information about links with the Nazis but this proved not to be the case.
