Painting by F. Luis Mora, depicting Lt(JG) Kalk assisting survivors of USS Jacob Jones (Destroyer # 61) after she was sunk by the German submarine U-53 off the Scilly Isles on 6 December 1917.
A plaque accompanying this painting read: "The Jacob Jones was sunk by an enemy torpedo between Brest and Queenstown. Lieutenant (jg) S.F. Kalk rendered conspicuous and gallant services after the ship sank by helping men from one raft to another so as to equalize the weight on the rafts. He died of exposure and exhaustion in order to save others. Lieutenant (jg) Kalk was awarded the Distinguished Service Medal posthumously."
