Old Norvicensians (ONs) are former pupils of Norwich School, an independent co-educational day public school in Norwich, England. It was founded in 1096 as an episcopal school by the first Bishop of Norwich, Herbert de Losinga, and is one of the longest surviving schools in the United Kingdom. It was refounded by royal charter in 1547 by Edward VI. ONs may join the Old Norvicensian Club of former pupils. Predecessors include the Parrian Club, a dining society for former pupils of Samuel Parr's headship in the late 18th century, and the Valpeian Club, after Edward Valpy in the early 19th century. In 1866, the latter gave way to the Norwich School Club, which became the current association for former pupils at the beginning of the 20th century.[1]
