Solomon III (died 919) was the Bishop of Constance from 890 to his death.
 In 885, the Emperor Charles III made him archchancellor of the Empire, for Konstanz was then the greatest diocese in Swabia, which had been Charles' original kingdom and was still his home most of the time.
 As well as bishop, he was also abbot of Reichenau and Saint Gall, immensely powerful abbeys in Swabia and the Rhineland.
 Solomon founded a church in honour of Saint Magnus at Saint Gall.
Ekkehard V (died c. 1220), called "Minimus" (the Least), was a monk of the Abbey of Saint Gall.
 He is the last of the Saint Gall Ekkehards, and flourished towards the end of the twelfth, and the beginning of the thirteenth, century.
 No particulars are known concerning his life, and tradition is silent as to his origin, the year of his birth and of his death.
 He was dean of the abbey in the reign of Innocent III.
The Abbey Library of Saint Gall was founded by Saint Othmar, the founder of the Abbey of St. Gall.
 During a fire in 937, the Abbey was destroyed, but the library remained intact.
 In 1983 the library together with the Abbey of St. Gall were made a World Heritage Site, as 'a perfect example of a great Carolingian monastery'.
The Abbey of Saint Gall (German: Abtei St. Gallen ) is a dissolved abbey (747–1805) in a Roman Catholic religious complex in the city of St. Gallen in Switzerland.
 The Carolingian-era monastery has existed since 719 and became an independent principality between 9th and 13th centuries, and was for many centuries one of the chief Benedictine abbeys in Europe.
 It was founded by Saint Othmar on the spot where Saint Gall had erected his hermitage.
 The library at the Abbey is one of the richest medieval libraries in the world.
 The city of St. Gallen originated as an adjoining settlement of the abbey.
 Following the secularization of the abbey around 1800 the former Abbey church became a Cathedral in 1848.
 Since 1983 the whole remaining abbey precinct has been a UNESCO World Heritage Site.
St. Gallen or traditionally St Gall, in German sometimes Sankt Gallen (   ; English: St Gall ; French: "Saint-Gall" ; Italian: "San Gallo" ; Romansh: "Son Gagl" ) is the capital of the canton of St. Gallen in Switzerland.
 It evolved from the hermitage of Saint Gall, founded in the 7th century.
 Today, it is a large urban agglomeration (with around 160,000 inhabitants) and represents the center of eastern Switzerland.
 Its economy consists mainly of the service sector.
Ekkehard I (Latin: "Eccehardus" ; died 14 January 973), called "Major" or "Senex" (the Elder), was a monk of the Abbey of Saint Gall.
 He was of noble birth, of the Jonschwyl family in Toggenburg, and was educated in the monastery of St. Gall; after joining the Benedictine Order, he was appointed director of the inner school there.
 Later, under Abbot Kralo, who trusted him implicitly, he was elected dean of the monastery, and for a while directed all the affairs of the abbey.
Notker the Stammerer (Latin: "Notcerus Balbulus" ; 840 – 6 April 912 AD), also called Notker I, Notker the Poet or Notker of Saint Gall, was a musician, author, poet, and Benedictine monk at the Abbey of Saint Gall in modern Switzerland.
 He is commonly accepted to be the "Monk of Saint Gall" ("Monachus Sangallensis") who wrote "Gesta Karoli", (the "deeds of Charlemagne").
Saint Tuotilo (Tutilo, Tutilo von Gallen, Tutilo of Gall, Tutilo of Saint Gall) (c. 850 – c. 915) was a medieval monk and composer.
Ekkehard III was a monk of the Abbey of Saint Gall and a nephew of Ekkehard I and a cousin of Ekkehard II.
 He shared the educational advantages of his cousin and, at his invitation, accompanied him to Hohentwiel to superintend and direct the studies of the local clergy.
 On his return to St. Gall he was made dean of the abbey, and is reported to have filled this office for thirty years.
 He died early in the eleventh century.
The Chronicon Suevicum universale (German: "Schwäbische Weltchronik" , "Swabian World Chronicle"), written around 1045 in Latin, is a chronicle of universal history in the form of annals for the years from Creation down to 1043.
 It was once commonly associated with the monastery of Saint Gall, but is now thought to have been composed by a monk of Reichenau.
 On the first hypothesis, it has been called the "Epitome Sangallense Herimanni Augiensis", a Saint Gall version of Hermann of Reichenau's chronicle.
 On the second, it has been called the "Reichenauer Weltchronik".
