Albrecht Durer was born on May 21, 1471, and was one of Eighteen(!)
children. He is considered one of the greatest German Renaissance
artists, and worked in a number of mediums, including watercolor and
charcoal, as well as exploring all manner of the engraving art--wood,
copper and zinc.
Aside from being a well known artist, he was also interested in
mathematics and did much to incorporate the use of geometry into art. He
also wrote and published a number of books, most of them dealing with
mathematics and artistic proportion, and how the two could be applied
together, to better art in general.
His works, many considered masterpieces in the use of art combined with
aspects of geometry, are now housed in great museums all over the world.
