As part of a series of murals devoted to famous Groningen professors, Barthel and colleagues realized an artistic mural for astronomer J.C. Kapteyn (1851-1922), founder of the Groningen Kapteyn Institute. In addition they produced an on-line animation for children on the life and works of Kapteyn; it can be viewed here.
