Karl H. Buesgen, Sr. (December 25, 1917-December 14, 1981) was an American landscape painter and Pennsylvania impressionist typically associated with the Baum Circle, a group of artists either taught by, associated with, or directly influenced by Pennsylvania impressionist painter Walter Emerson Baum.
A musician by trade, Buesgen studied painting with Walter Emerson Baum (1884-1956) and John E. Berninger (1897-1981). Like many impressionist painters, Buesgen painted landscapes en plein air (directly from nature) or from colored slides of photographs he took with his camera.
The greatest influence to Buesgen's work was John E. Berninger. The two were first associated as teacher and student, and soon became fast friends who shared a passion for music and art. Over the course of 40 years, the two spent nearly every Saturday afternoon visiting and discussing their interests and Sunday afternoons painting. They scouted sites throughout Lehigh County at which to set up their easels and paint or, if the weather was not satisfactory, spent their time painting in Berninger's third floor "studio" at his home near Allentown's West Park.
This relationship continued until Berninger's death in 1981. Buesgen died later that same year.
During 2005, an exhibition of his works were shown at an exhibit in the David E. Rodale Gallery at the Baum School of Art. In 2006, Buesgen's work was included in an exhibition at the David E. Rodale Gallery at the Baum School of Art highlighting the work of the Baum Circle.
