His father was the decorative painter and village Elder, Danckwardt Pasch (1660-1727), who originally came from Lübeck.
There, he was introduced to the art community by his fellow Swedes, Michael Dahl and Hans Hysing.
He returned to Stockholm in 1728, after his father's death, due to disputes involving inheritance.
Two years later, he married Anna Helena Beckman (1706-1756), the daughter of a local official.
Much of his work shows the influence of William Hogarth, although he is also credited with helping to introduce the Rococo style into Sweden.
