Deruet was made a noble by the Duke of Lorraine in 1621, and was then made a Knight of the Order of St Michel in 1645 by Louis XIII, who had in 1641 absorbed most of Lorraine into France. He had a luxurious residence in Nancy, named La Romaine, where Louis XIII and his Queen stayed in 1633.
Claude Lorrain was an apprentice to Claude Deruet in 1623 for one year. He also married and had two sons, one of whom became a painter.
American architect DeWitt H. Fessenden wrote a biography of Deruet, The Life and Works of Claude Deruet, in 1952.
