Nigel (c. 1100 – 1169) (sometimes Nigel Poor or Nigel of Ely) was an Anglo-Norman bishop of Ely. He came from an ecclesiastical family; his uncle Roger of Salisbury was a bishop and government minister for King Henry I, and other relatives also held offices in the English Church and government. Nigel owed his advancement to his uncle, as did Nigel's probable brother Alexander, who like Nigel was advanced to episcopal status. Nigel was educated on the continent before becoming a royal administrator. He served as Treasurer of England under King Henry I of England, before being appointed to the see, or bishopric, of Ely in 1133. Following the accession of Henry I's successor, King Stephen, Nigel remained as treasurer only briefly before his family was ousted from political office by the new king. Nigel rebelled and deserted to Stephen's rival Matilda, but eventually reconciled with Stephen. On the king's death, Nigel was returned to the treasurership by the new king, Henry II. Nigel's second tenure as treasurer saw him return the administration to the practices of Henry I. Most historians, then and now, have felt that Nigel's administrative abilities were excellent; he is considered to have been more talented as an administrator than as a religious figure.
