Pandulf of Pisa
Pandulf of Pisa was a twelfth-century Italian Cardinal, and biographer of several contemporary popes; these biographies belonged to the Liber Pontificalis. He was nephew of Hugo of Alatri. Works attributed to him appeared in the Rerum Italicarum scriptores by Ludovico Antonio Muratori; some of those attributions have been changed.
According to Robinson Pandulf's biography of Gelasius II is inaccurate in electoral details, and had a polemic purpose relating to the schism of 1130. Pandulf is thought to have been an intimate friend of Gelasius, and in the schism after 1130 supported antipope Anacletus II against Innocent II. Anacletus named him cardinal-deacon of SS. Cosma e Damiano; as such, he signed the bulls of this antipope on February 8, 1131, December 7, 1134 and March 21, 1137.
