Jacob Mogensen, or Ebbe Ulfeldt (c. 1600 – c. 1670), was the brother of the Danish naval officer
Corfits Ulfeldt, and became a landscape painter in
Delft.
According to the RKD he was a registered pupil of
Jacob Vosmaer. He is probably the "
Delvenaar" referred to as "Ugaart", in
Arnold Houbraken's '' Schouburg''. According to Houbraken, Ugaart Delvenaar was a good landscape painter who lived in the same period as
Jan Verkolje.
