1471 Edmund Beaufort 4th Duke of Somerset an English nobleman, and a military commander during the Wars of the Roses, in which he supported the House of Lancaster.
1475 Dieric Bouts an Early Netherlandish painter. According to Karel van Mander in his Het Schilderboeck of 1604, Bouts was born in Haarlem and was mainly active in Leuven , where he was city painter from 1468. Van Mander confused the issue by writing biographies of both "Dieric of Haarlem" and "Dieric of Leuven," although he was referring to the same artist. The similarity of their last names also led to the confusion of Bouts with Hubrecht Stuerbout, a prominent sculptor in Leuven. Very little is actually known about Bouts' early life, but he was greatly influenced by Jan van Eyck and by Rogier van der Weyden, under whom he may have studied. He is first documented in Leuven in 1457 and worked there until his death in 1475
1502 James Tyrrell an English knight, a trusted servant of King Richard III of England. He is known for confessing to the murders of the Princes in the Tower under Richard's orders.

1814 Georg Joseph Vogler a German composer, organist, teacher and theorist.

His greatest successes came as performer and designer for the organ at various courts and cities around Europe, as well as a teacher, attracting highly successful and devoted pupils such as Carl Maria von Weber. His career as a music theorist and composer however was mixed, with contemporaries such as Mozart believing Vogler to have been a charlatan. Despite his mixed reception in his own life, his highly-original contributions in many areas of music and influence on his pupils endured, and combined with his eccentric and adventurous career, prompted one historian to summarize Vogler as "one of the most bizarre characters in the history of music"
