Peter worked for 42 years at Dubuque Bank and Trust in the computer department.
Peter enjoyed fishing, camping, and riding his bike along the Mississippi River, Heritage Trail and Mackinac Island. He also liked listening to KDTH, reading the TH, and balancing his checkbook. He loved cheering for the Iowa Hawkeyes, Green Bay Packers, Chicago Cubs, and the Wahlert Eagles, but loved most of all cheering for his grandkids at their sporting events.
