Adriaan Van Roomen
Adriaan van Roomen (29 September 1561 – 4 May 1615), also known as Adrianus Romanus, was a mathematician, professor of medicine and medical astronomer from the Duchy of Brabant in the Habsburg Netherlands who was active throughout Central Europe in the late 16th and early 17th centuries. As a mathematician he worked in algebra, trigonometry and geometry; and on the decimal expansion of π. He solved the Problem of Apollonius using a new method that involved intersecting hyperbolas. He also wrote on the Gregorian calendar reform. Life Van Roomen was born in Leuven, the son of Adriaan Van Roomen and Maria Van Den Daele. He was educated partly in Leuven and partly After studying at the Jesuit College in Cologne, also attending the University of Cologne where he began his study of medicine.Henri Bosmans, "Romain (Adrien)", ''Biographie Nationale de Belgique''vol. 19(Brussels), 848-888. He also briefly studied medicine at Leuven University. Roomen was professor of mathematics and m ...

Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, structure, space, models, and change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman mathematician recorded by history was Hypati ...

Collegiate Church
In Christianity, a collegiate church is a church where the daily office of worship is maintained by a college of canons: a non-monastic or "secular" community of clergy, organised as a self-governing corporate body, which may be presided over by a dean or provost. In its governance and religious observance a collegiate church is similar to a cathedral, although a collegiate church is not the seat of a bishop and has no diocesan responsibilities. Collegiate churches were often supported by extensive lands held by the church, or by tithe income from appropriated benefices. They commonly provide distinct spaces for congregational worship and for the choir offices of their clerical community. History In the early medieval period, before the development of the parish system in Western Christianity, many new church foundations were staffed by groups of secular priests, living a communal life and serving an extensive territory. In England these churches were termed minsters, from th ...

Priest
A priest is a religious leader authorized to perform the sacred rituals of a religion, especially as a mediatory agent between humans and one or more deities. They also have the authority or power to administer religious rites; in particular, rites of sacrifice to, and propitiation of, a deity or deities. Their office or position is the 'priesthood', a term which also may apply to such persons collectively. A priest may have the duty to hear confessions periodically, give marriage counseling, provide prenuptial counseling, give spiritual direction, teach catechism, or visit those confined indoors, such as the sick in hospitals and nursing homes. Description According to the trifunctional hypothesis of prehistoric Proto-Indo-European society, priests have existed since the earliest of times and in the simplest societies, most likely as a result of agricultural surplus and consequent social stratification. The necessity to read sacred texts and keep temple or church rec ...

MacTutor History Of Mathematics Archive
The MacTutor History of Mathematics archive is a website maintained by John J. O'Connor and Edmund F. Robertson and hosted by the University of St Andrews in Scotland. It contains detailed biographies on many historical and contemporary mathematicians, as well as information on famous curves and various topics in the history of mathematics. The History of Mathematics archive was an outgrowth of Mathematical MacTutor system, a HyperCard database by the same authors, which won them the European Academic Software award in 1994. In the same year, they founded their web site. it has biographies on over 2800 mathematicians and scientists. In 2015, O'Connor and Robertson won the Hirst Prize of the London Mathematical Society for their work... The citation for the Hirst Prize calls the archive "the most widely used and influential web-based resource in history of mathematics".

Julius Echter Von Mespelbrunn
Julius Echter von Mespelbrunn (18 March 1545 – 9 September 1617) was Prince-Bishop of Würzburg from 1573. He was born in Mespelbrunn Castle, Spessart ( Lower Franconia) and died in Würzburg. Life He was educated in Mainz, Leuven, Douai, Paris, Angers, Pavia, and Rome. In Rome he became a licentiate of canon and civil law. In 1567 he entered on his duties as canon of Würzburg, an office to which he had been appointed in 1554; in 1570 he became the dean of the cathedral chapter, and in 1573, at the age of twenty-eight, even before his ordination to the priesthood, was appointed to the office of the Prince-Bishop of Würzburg. During the first ten years of Echter's government, the attempt to unite the Abbey of Fulda and the Bishopric of Würzburg, after the deposition of the Prince-Abbot Balthasar von Dernbach, caused much confusion. From the beginning, he carried out a thorough ecclesiastical restoration. To this end, he promoted the Jesuits and their ...

Rudolf II
Rudolf II (18 July 1552 – 20 January 1612) was Holy Roman Emperor (1576–1612), King of Hungary and Kingdom of Croatia (Habsburg), Croatia (as Rudolf I, 1572–1608), King of Bohemia (1575–1608/1611) and Archduke of Austria (1576–1608). He was a member of the House of Habsburg. Rudolf's legacy has traditionally been viewed in three ways:Hotson, 1999. an ineffectual ruler whose mistakes led directly to the Thirty Years' War; a great and influential patron of Northern Mannerism, Northern Mannerist art; and an intellectual devotee of occult arts and learning which helped seed what would be called the Scientific Revolution. Determined to unify Christendom, he initiated the Long Turkish War (1593–1606) with the Ottoman Empire. Exhausted by war, his citizens in Hungary revolted in the Bocskai uprising, Bocskai Uprising, which led to more authority given to his brother Matthias, Holy Roman Emperor, Matthias. Under his reign, there was a policy of toleration towards Judaism ...

Oxford Dictionary Of National Biography
The ''Dictionary of National Biography'' (''DNB'') is a standard work of reference on notable figures from British history, published since 1885. The updated ''Oxford Dictionary of National Biography'' (''ODNB'') was published on 23 September 2004 in 60 volumes and online, with 50,113 biographical articles covering 54,922 lives. First series Hoping to emulate national biographical collections published elsewhere in Europe, such as the '' Allgemeine Deutsche Biographie'' (1875), in 1882 the publisher George Smith (1824–1901), of Smith, Elder & Co., planned a universal dictionary that would include biographical entries on individuals from world history. He approached Leslie Stephen, then editor of the ''Cornhill Magazine'', owned by Smith, to become the editor. Stephen persuaded Smith that the work should focus only on subjects from the United Kingdom and its present and former colonies. An early working title was the ''Biographia Britannica'', the name of an earlier eightee ...

Floruit
''Floruit'' (; abbreviated fl. or occasionally flor.; from Latin for "they flourished") denotes a date or period during which a person was known to have been alive or active. In English, the unabbreviated word may also be used as a noun indicating the time when someone flourished. Etymology and use la, flōruit is the third-person singular perfect active indicative of the Latin verb ', ' "to bloom, flower, or flourish", from the noun ', ', "flower". Broadly, the term is employed in reference to the peak of activity for a person or movement. More specifically, it often is used in genealogy and historical writing when a person's birth or death dates are unknown, but some other evidence exists that indicates when they were alive. For example, if there are wills attested by John Jones in 1204, and 1229, and a record of his marriage in 1197, a record concerning him might be written as "John Jones (fl. 1197–1229)". The term is often used in art history when dating the career ...
