(b Amsterdam, 1643; d The Hague, 1712). Dutch draughtsman and painter. By 1648 his family was in Haarlem, where he entered the Guild of St Luke at the age of 16. He went to Paris in the mid-1660s, returning via Maastricht where he made drawings in 1669–71. Between 1672 and 1676 he was employed as an engineering officer with the army of the Dutch States-General under the Stadholder Prince William III of Orange Nassau. The drawings made during these years are of places in the southern Netherlands, and some include scenes of military activity, but never battles. De Grave settled in The Hague after 1678 and was employed again in the army in 1711.
