Sir James Guthrie (1859-1930) was one of the Glasgow Boys, a group of late-19th century Scottish painters influenced by French realist Jules Bastien-Lepage.
Like some other artists of middle-class origin in those days, his family sent him to university with the idea that he would practice law. And like the others he abandoned that line of education to take up art, though his art training came largely by self-education.
Regardless of how he mastered his skills, Guthrie became one of the most prominent Scottish artists of his time. By 1902 he was president of the Royal Scottish Academy and in 1903 was knighted.
The best place to find Guthrie's painting is Glasgow, of all places. Unfortunately for me, the last time I was in Glasgow I hadn't yet launched into serious study of art history and skated through Kelvingrove faster than I really should have.
