Adalbert Atto (or Adalberto Azzo) (died 13 February 988) was the first Count of Canossa and founder of that noble house which eventually was to play a determinant rôle in the political settling of Italy and the Investiture Controversy in the eleventh and twelfth centuries.
Adalbert first appears in sources as a son of Sigifred of Lucca. He was originally a vassal of King Lothair II and a miles of Adelard, Bishop of Reggio. He rose to prominence rapidly by sheltering Queen Adelaide in his castle at Canossa after she fled from the castle of Garda (951), where Berengar II had imprisoned her.
In 958, he was made a count sine re, by Adelaide. He did not appear again as a count in documents until December 961, during Berengar's ascendancy. On 20 April 962, he appeared as count of Reggio and Modena (comes Regensis sive Mutinensis). These appointments were probably a further product of his support for Adelaide and her new husband, Otto I of Germany. With the queen, he negotiated a division of power with the bishop of Reggio whereby the bishop was confirmed as comes civitatis, count of the city, and Adalbert as comes comitatus, count of the county, where the county was said to begin three or four miles outside the city walls. He appears with a similar title, comes comitatus Mantuanensis, in Mantua in a letter of the abbess of Santa Giulia dated 10 June 977.
Atto- (symbol a) is a unit prefix in the metric system denoting a factor of 10−18 or 0.000000000000000001.
The unit multiple was adopted at the 12th General Conference on Weights and Measures (CGPM) in Resolution 8. It is derived from the Danish word atten, meaning "eighteen".

Adalbert may refer to:
Adalbert (fl. 1043 x 1072) was an 11th-century prelate. Having been consecrated elsewhere, he is said by the Saxon writer Adam of Bremen to have been sent to become Bishop of Orkney by his namesake, Adalbert, Archbishop of Hamburg. He is mentioned as the successor of Bishop John.
Adam of Bremen relates that a cleric called Albert was established as the first bishop in Trondheim, an event datable to some point between 1067 and 1093. It is possible that Adalbert and Albert are the same person.
Aldebert, or Adalbert, was a preacher in 8th century Gaul. He claimed that an angel had conferred miraculous powers on him at his birth and that another had brought him relics of great sanctity from all parts of the earth. He also claimed to be able to see the future and read people's thoughts, telling those who came to him that they had no need to confess, since he knew what they had done, and that their sins were forgiven.
Adalbert appeared in the district of Soissons sometime in the 8th century and practised and preached a life of Apostolic poverty. He was banned by the local bishop from preaching in churches, and preached in the countryside, in the open air and later in churches that his followers (he had acquired many of them) had built for him.
According to St Boniface, he erected crucifixes at fields and springs. According to the same saint, Adalbert had also claimed to have received a letter that Jesus Christ had given from heaven to Jerusalem, which Aldebert used in his own preachings.
