Count Erik Jönsson Dahlbergh (10 October 1625 – 16 January 1703) was a Swedish military engineer, Governor-general, Field marshal and Master-general of the Ordinance. He rose to the level of nobility through his military competence. According to Cathal Nolan, Count Dahlberg was a highly innovative military engineer in the 17th and 18th century, often referred to as the "Swedish Vauban". He was expert in both building and destroying fortifications. In warfare he won several sieges, including Copenhagen and Kronborg.
