Andrew Peterson was born Anders Petterson on October 20, 1818, on a farm in Sjöarp, Västra Ryd, Östergötland, Sweden. His family had financial ties to the church, so he and his brother received a better education than many farmers of the time. He had interests in music, and experimental agricultural and farm techniques.
In 1850, at thirty-two years old, Andrew Peterson immigrated to the United States, arriving in Boston on July 2. During his voyage, Peterson began keeping a daily journal. He would continue writing for the next forty-eight years, until two days before his death. Most of the early journals were unfortunately later lost. From Boston, he traveled west to Peru, Illinois, and then on to a settlement called New Sweden, near Burlington, Iowa. While in Iowa, Peterson “Americanized” his name, from Anders Petterson to Andrew Peterson.
In 1853, wanting land of his own rather than working for others, Peterson visited Minnesota, where he filed a claim for a farm. Two years later, on May 4, 1855, Peterson left for Minnesota permanently with his sister and her family. He settled on his claim close to a community called Scandia, near Waconia. He began an orchard on his land, as well as farming more traditional crops. The farm was his by December 6, 1856. During these years, Peterson was a founder of the Scandia Baptist Church. Meetings were held in his home. A church building was erected not long after.
Peterson visited nearby King Oscar’s settlement, near the twenty-first century town of East Union, to buy more trees and grafts for his orchard. While there, he met a woman named Elsa. They married in 1858 when he was forty and she was twenty-three. They had nine children: Ida, George, John, Charles (Carl), Frank, Emma, Anna, Josephine and Oscar. He continued his daily diary, recording trips to town, work on the farm, visits with neighbors, and his thoughts on the U.S.–Dakota War of 1862. His orchard blossomed, with the farm producing apples, pears, plums, grapes, and cherries.
In 1874, Peterson joined the Patrons of Husbandry, a national fellowship of farmers. He sent apple grafts to growers as far away as Iowa. His experimental work was recognized at the January 1888 annual meeting of the Minnesota Horticultural Society. He received an honorary life membership, by unanimous vote.
At its height, his orchard produced over two hundred varieties of apples. Peterson hosted tours to leading experts in the field from nearby states and as far away as Ottawa, Canada. Later, his orchard became one of fifteen experimental fruit breeding research stations in Minnesota, run by the Minnesota Horticultural Society. His farm was located six miles from what would become the University of Minnesota Landscape Arboretum and Horticultural Research Center.
Peterson died on March 31, 1898. His wife Elsa Peterson ran the farm with her children until her death March 8, 1922. As their children died with no heirs, his last daughter Emma gave the farm to Sarah Peterson, a neighbor who had cared for Emma in her old age. The farm then passed into the hands of the Holasek family, who renamed it Rock Isle Farm.
The Andrew Peterson farmstead was placed on the National Register of Historic Places in 1978. His children donated Peterson’s diaries to the Minnesota Historical Society in the 1930s. Swedish novelist Wilhelm Moberg discovered them while visiting Minnesota for research in the 1940s. He used the journals as the basis of his four novels: The Emigrants, Unto a Good Land, The Settlers, and The Last Letter Home. A musical called Andrew Peterson: The Genuine Pioneer Story had great success in Sweden in 2012. In the twenty-first century, Carver County is sister counties with Ydre, Sweden, Peterson’s home county. The Carver County Historical Society restored the granary on the farmstead in 2006 with help from Swedish carpenters, and began restoration on the north barn in 2010.
