Kalle's real name was Karl August Gabriel Lindgren, born in 1898 in Stugund outside Söderhamn. For decades, this forest wanderer was a well-known and appreciated odd profile, who year after year wandered from Gästrikegränsen, through Hälsingland, Härjedalen and Jämtland up to Lapland, where he turned and wandered south through Ångermanland and Medelpad. His eternal wanderings extend from the end of the 20th century until his dramatic death in November 1957 near Morvallsbyn in Västra Hälsingland.
