1. M. A. DE RUIJTER (the statue in the picture): Wikipedia says:
Michiel Adriaenszoon de Ruyter (IPA: [miˈxil ˈaːdrijaːnˌsoːn də ˈrœytər]; 24 March 1607 – 29 April 1676) was a Dutch admiral. Widely celebrated and regarded as one of the most skilled admirals in history, De Ruyter is arguably most famous for his achievements with the Dutch Navy during the Anglo-Dutch Wars. He fought the English and French forces and scored several critical victories, with the Raid on the Medway being the most famous among them.
