He attained a great deal of fame during his lifetime as a painter of the famous (including royalty and three American presidents), and this allowed him a great accumulation of wealth during his lifetime. He used this money primarily to build a substantial art collection, which he donated to the Swedish state upon his death, and also to purchase 40 timber houses which Zorn wished to preserve to ensure that the art of traditional timber building was not forgotten. This reflects the respect of Zorn for his other great subject of painting, which was poor and working people, and rural environments.
