He was proclaimed Blessed in 1744.
Born in Bologna as the son of Pier Nicola Albergati, he entered the Carthusian order in 1394, at the age of twenty. A supporter of the authority of Pope Martin V following the Western Schism, he was appointed as Bishop of Bologna by the latter in 1417 and made his native city a center of learning.
Albergati was employed as an ambassador by several popes; in that capacity he visited France and several of the other Italian states. He represented Pope Eugene IV at the 1435 Congress of Arras. The congress failed to make peace between England and France, but it did effect a reconciliation between Philip the Good of Burgundy and the French crown. He was made the Cardinal-Priest of Santa Croce in Gerusalemme in 1426. He played a role in the Council of Basel-Ferrara-Florence and opened the Council of Florence, which brought about a short-lived union of the Latin and Greek Churches.
Among the young scholars under his tutelage were future important figures such as Pope Nicholas V and Pope Pius II as well as Francesco Filelfo. He had ordained and consecrated Nicholas V and served as a great influence upon him, so much so that the latter chose the pontifical name of "Nicholas" upon his ascension to the pontificate in honor of Albergati. He died at Siena in 1443.
Albergati was beatified on 25 September 1744.
