He was in France and Italy and trained as a painter, but initially was only an insignificant and little fertile artist in portrait art.
He returned to Denmark around 1670, and already in 1672 it is documented that he received payment of three skillings for works he had delivered for Rosenborg Castle.
Among his paintings are: Grodtschilling the Elder's portrait, now at Rosenborg Castle, Christian V of Denmark on horseback, at the old Copenhagen Castle, and an "optical piece": the Oldenburg kings with Christian V in the middle.
He also had drawings for Rosenborg Castle wallpapers (except for those in the Great Hall and data sheet.
For their 12 children, most died young, but one son Bendix Grodtschilling the Youngest became a painter as well.
