Biography
His family had a long history in the priesthood, beginning with , from Blacksta Parish in Södermanland. His father, Adolf, was a sea captain. When he was eight, he accompanied his father on a voyage that would last for six years. He received his education from local, private schools while the ship was in port. Upon their return to Sweden, he was apprenticed to the lithographer, Karl Fredrik Natanael Schultén, who was his mother's half-brother. At the same time, he took classes at the Royal Swedish Academy of Fine Arts. In 1844, after travelling around Sweden, he went to Finland where he stayed for five years; making his living by painting portraits.
