After moving to Amsterdam in 1837, Royer received many public commissions for statues of leading personalities from Dutch history, such as the statues of Rembrandt and Joost van den Vondel in Amsterdam, William the Silent in The Hague and Michiel de Ruyter in Vlissingen [REF].
After his death in Amsterdam in 1868, Royer's widow offered the estate of her husband to the Dutch State.
