On Sunday 21 April, 1822, along with two friends, four brothers, Jacobus, Pieter, George and Dirk Lodewijk Bennewitz went sailing on the Legmeersepoel near Amstelveen. A trip which was to become a great tragedy. At 1:30pm thier boat capsized and five of the young men drown. The sixteen year old George Bennewitz, the youngest son of Dirk Lodewijk Bennewitz was the only son who managed to survive by clinging to the capsized boat. The second oldest, Jacobus Bennewitz, was noted for his artistic talent in silversmithing. At the time of his death, Jacobus had registered his own mark. As this plaque bears the signature of J. Bennewitz, one could asume that this piece is the work of Jacobus and dates somewhere between 1815 and the time of his death.
