Today is also the feast day of St. Amand (c. 584 CE–679 CE). He was known for his hospitality, and is the patron saint of all who produce beer: brewers, innkeepers and bartenders and was also known as Amandus, Amandus of Elnon and Amantius. He was a bishop of Tongeren-Maastricht and one of the great Christian missionaries of Flanders. He is venerated as a saint, particularly in France and Belgium. He was born in Poitou, France, and died in the monastery at Elnone-en-Pevele (modern Saint-Amand-les-Eaux), France.

This account of his life is by T.J. Campbell from the Catholic Encyclopedia:

One of the great apostles of Flanders; born near Nantes, in France, about the end of the sixth century. He was, apparently, of noble extraction. When a youth of twenty, he fled from his home and became a monk near Tours, resisting all the efforts of his family to withdraw him from his mode of life. Following what he regarded as divine inspiration, he betook himself to Bourges, where under the direction of Saint Austregisile, the bishop of the city, he remained in solitude for fifteen years, living in a cell and subsisting on bread and water. After a pilgrimage to Rome, he was consecrated in France as a missionary bishop at the age of thirty-three. At the request of Clotaire II, he began first to evangelize the inhabitants of Ghent, who were then degraded idolaters, and afterwards extended his work throughout all Flanders, suffering persecution, and undergoing great hardship but achieving nothing, until the miracle of restoring the life of a criminal who had been hanged, changed the feelings of the people to reverence and affection and brought many converts to the faith. Monasteries at Ghent and Mt. Blandin were erected. They were the first monuments to the Faith in Belgium. Returning to France, in 630, he incurred the enmity of King Dagobert, who he had endeavoured to recall from a sinful life, and was expelled from the kingdom. Dagobert afterwards entreated him to return, asked pardon for the wrong done, and requested him to be tutor of the heir of the throne. The danger of living at court prompted the Saint to refuse the honour. His next apostolate was among of the Slavs of the Danube, but it met with no success, and we find him then in Rome, reporting to the pope what results had been achieved.

While returning to France he is said to have calmed a storm at sea. He was made Bishop of Maastricht about the year 649, but unable the repress the disorders of the place, he appealed to the Pope, Martin I, for instructions. The reply traced his plan of action with regard to fractious clerics, and also contained information about the Monothelite heresy, which was then desolating the East. Amandus was also commissioned to convoke councils in Neustria and Austrasia in order to have the decrees which had been passed at Rome read to the bishops of Gaul, who in turn commissioned him to bear the acts of their councils to the Sovereign Pontiff. He availed himself of this occasion to obtain his release from the bishopric of Maastricht, and to resume his work as a missionary. It was at this time that he entered into relations with the family of Pepin of Landen, and helped Saint Gertrude and Saint Itta to establish their famous monastery of Nivelles. Thirty years before he had gone into the Basque country to preach, but had met with little success. He was now requested by the inhabitants to return, and although seventy years old, he undertook the work of evangelizing them and appears to have banished idolatry from the land. Returning again to his country, he founded several monasteries, on one occasion at the risk of his life. Belgium especially boasts many of his foundations. Dagobert made great concessions to him for his various establishments. He died in his monastery of Elnon, at the age of ninety. His feast is kept 6 February.

And this history is from Catholic Online:

This great missionary was born in lower Poitou about the year 584. At the age of twenty, he retired to a small monastery in the island of Yeu, near that of Re. He had not been there more than a year when his father discovered him and tried to persuade him to return home. When he threatened to disinherit him, the saint cheerfully replied, “Christ is my only inheritance.” Amand afterward went to Tours, where he was ordained, and then to Bourges, where he lived fifteen years under the direction of St. Austregisilus, the bishop, in a cell near the cathedral. After a pilgrimage to Rome, he returned to France and was consecrated bishop in 629 without any fixed See, receiving a general commission to teach the Faith to the heathens. He preached the gospel in Flanders and northern France, with a brief excursion to the Slavs in Carinthia and perhaps, to Gascony. He reproved King Dagobert I for his crimes and accordingly, was banished. But Dagobert soon recalled him, and asked him to baptize his newborn son Sigebert, afterwards to become a king and a saint. The people about Ghent were so ferociously hostile that no preacher dared venture among them. This moved Amand to attempt that mission, in the course of which he was sometimes beaten and thrown into the river. He persevered, however, and in the end people came in crowds droves to be baptized.

As well as being a great missionary, St. Amand was a father of monasticism in ancient Belgium, and a score of monasteries claimed him as founder. He found houses at Elnone (Saint-Amand-les-Eaux), near Tournai, which became his headquarters, St. Peters on Mont-Blendin at Ghent, but probably not St. Bavo’s there as well; Nivells, for nuns, with Blessed Ida and St. Gertrude, Barisis-au-Bois, and probably three more. It is said, though possibly apocryphal, that in 646 he was chosen bishop of Maestricht, but that three years later, he resigned that See to St. Remaclus and returned to the missions which he had always had most at heart. He continued his labors among the heathens until a great age, when, broken with infirmities, he retired to Elnone. There he governed as Abbot for four years, spending his time in preparing for the death which came to him at last soon after 676. That St. Amand was one of the most imposing figures of the Merovingian epoch, is disputed by no serious historian; he was not unknown in England, and the pre-Reformation chapel of the Eyston family at east Hendred in Birkshire is dedicated in his honor.

He has quite a few patronages, including the Boy Scouts, bar staff, barkeepers, bartenders, brewers, grocers, hop growers, hotel keepers, innkeepers, merchants, pharmacists, druggists, vinegar makers, vine growers, vintners, wine-makers, and wine merchants; plus he’s against diseases of cattle, against fever, against paralysis, against rheumatism, against seizures, against skin diseases, against vision problems; and of the places: Flanders, Belgium; Maastricht, Netherlands; Salzburg, Austria; Utrecht, Netherlands; and Wingene, Belgium.
