Albert Brudzewski given name Wojciech
Albert Brudzewski, also Albert Blar (of Brudzewo), Albert of Brudzewo or Wojciech Brudzewski (in Latin, Albertus de Brudzewo; c.1445–c.1497) was a Polish astronomer, mathematician,  philosopher and diplomat.Life
Albert (in Polish, Wojciech), who would sign himself "de Brudzewo" ("of Brudzewo"), was born about 1445, in Brudzewo, near Kalisz. Scant information exists about his early life.  It is only known that as a 23-year-old he matriculated at the Kraków Academy (now Jagiellonian University), where he remained through nearly all his life, teaching there for two decades.  He served as the academy's dean, as procurator (administrator of its property), and as head of the Bursa Hungarorum ("Hungarians' Dormitory").
Albert is remembered as a remarkable teacher.  At the Kraków Academy he impressed students by his extraordinary knowledge of literature, and taught mathematics and astronomy.  When in 1490 he became a bachelor of theology, he also lectured on Aristotle's philosophy.  These lectures were attended by Nicolaus Copernicus, who enrolled at the academy in 1491.  A major accomplishment of Albert's was his modernization of the teaching of astronomy by introducing the most up-to-date  texts.
Albert was well versed in Georg von Peuerbach's Theory of the Planets and Regiomontanus' Astronomical Tables.  He was skeptical of the geocentric system.  He was the first to state that the Moon moves in an ellipse and always shows its same side to the Earth.He drew up tables for calculating the positions of heavenly bodies.  In 1482 he wrote a Commentariolum super Theoricas novas planetarum Georgii Purbachii [...] per Albertum de Brudzewo — a commentary on Georg von Peuerbach's text, Theoricae novae planetarum – New Theories of the Planets — published in Milan, Mediolani, in 1495, by his pupil, Jan Otto de Kraceusae with this title Commentaria utilissima in theoricis planetarum.
Besides Copernicus, Albert's students included the mathematician Bernard Wapowski and the German poet and Renaissance humanist, Conrad Celtis, who in Kraków established the first Central European literary society, Sodalitas Litterana Vistulana.
In 1495, at the behest of Cardinal Fryderyk Jagiellończyk (Frederick Jagiellon), Brudzewski moved to Vilnius as secretary to Grand Duke of Lithuania Aleksander Jagiellon, who would later become King Alexander of Poland.  He served the Grand Duke as a diplomat; one of his most important missions involved negotiations with Muscovy's Tsar Ivan the Terrible.  It was in Vilnius that Albert wrote his treatise, Conciliator, the original of which has not yet been found.
Albert of Brudzewo died in Vilnius.  The exact date of his death is not known; some sources state that he died at the age of fifty.
