Jacob van Wassenaer Obdam

Jacob van Wassenaer Obdam was a Dutch States Navy officer and nobleman who became lieutenant admiral, and supreme commander of the Dutch navy. He had as official titles Banner Lord of Wassenaer, and Lord Obdam, Hensbroek, Spanbroek, Opmeer, Zuidwijk and Kernhem. The name Obdam was then also spelled as Opdam. Contemporary English sources typically refer to him as Admiral Opdam or Lord Obdam because it was not until 1657 that he bought the Wassenaar Estate from relatives and thus acquired its title. Modern Dutch sources sometimes less correctly insert a second "van" between "Wassenaer" and "Obdam" or use the modern spelling "Wassenaar".
