text: Robert de Sigello
  
  Robert de Sigello (died 1150) was a medieval Bishop of London and Lord Chancellor of England.
  
  Life
  
  Robert was keeper of the king's seal, usually known as Lord Chancellor from 1133 to 1135. He at one point was a monk at Reading Abbey, where he may have forged charters in favour of the abbey.
  
  Robert was nominated to the see of London by the Empress Matilda and consecrated in 1141, possibly about July. He died in 1150, and as his death was commemorated on both 28 September and 29 September, he probably died on one of those dates in 1150.
