Alexander Young Jackson (October 3, 1882 - April 5, 1974) was a Canadian painter and a founding member of the Group of Seven.
As a young boy, Jackson worked as an office boy for a lithograph company, after his father abandoned his family of six children. It was at this company that Jackson began his art training. In the evenings, he took classes at Montreal's Monument-National
In 1905, Jackson worked his way to Europe on a cattle boat, returning by the same means and travelling on to Chicago. In Chicago, he joined a commercial art firm and took courses at the Art Institute of Chicago. He saved his earnings and, by 1907, was able to visit France to study Impressionism. In France, Jackson decided to become a professional painter, studying at Paris' Academie Julian under J.P. Laurens.
