Anton Zilwicki is a fictional character in the Honorverse, a series of military science fiction novels written by David Weber. Zilwicki's first appearance takes place in The Short Victorious War, when he and his daughter must witness the death of his wife Captain Helen Zilwicki, who sacrificed herself to protect the convoy they were traveling onboard from a group of Havenite warships. While he claims his specialty was electronic intelligence (breaking into computer systems), he has proved himself to be an adequate field intelligence officer.
