Eighteen years carving a son's memorial
Kollwitz's son Peter volunteered in 1914, after she persuaded her husband Karl to consent, and was killed near Diksmuide in Flanders that October at eighteen. She conceived a memorial within weeks, repeatedly abandoned and destroyed versions, and only in 1932 installed two kneeling granite figures, a mother and a father bearing her and Karl's features, facing his grave at Roggevelde, later moved to Vladslo. The finished work shows no soldier at all, only the parents.
