Throughout his life, Charles excelled in drawing. By the time he entered Yeatman High School, he had proved his proficiency—as well as his humor—in the art form.
Charles made drawings for his school’s yearbook as well as engineering pieces for the Laclede Steel Company where he worked in his teens. He continued developing his skill at Washington University in St. Louis while studying architecture (where he excelled in esquisse—a preliminary sketch of a design problem). He made Christmas cards for himself and family members, and even continued to draw later in life while telling stories to his grandchildren.
These two sketches serve as examples of the drawings Charles made on his extended honeymoon with first wife, Catherine Dewey Woermann, a fellow architecture student at Washington University. The newlyweds spent several months in Europe visiting centuries-old architecture as well as more recent modernist buildings.
