Lars Levi Laestadius was a Swedish Sami writer, ecologist, mythologist, and ethnographer as well as a pastor and administrator of the Swedish state Lutheran church in Lapland who founded the Laestadian pietist revival movement to help his largely Sami congregations, who were being ravaged by alcoholism. Laestadius himself became a teetotaller in the 1840s, when he began successfully talking his Sami parishioners out of alcoholism. Laestadius was also a noted botanist and an author.
