Feature for Today
Thumbnail of Charles Willson Peale

On 15 Apr 1741, Charles Willson Peale was born, who in early life was a portrait painter, with many famous people captured in his oil paintings. In later life, he opened an art museum to show his growing collection of artworks. Then, by chance, his attention was turned to natural science. He was offered some mammoth bones to display as an additional curiosity to draw people into his museum. From that small beginning, he started collecting items to exhibit in what became the first U.S. popular Museum of Natural Science and Art.

Later, he went on a full scale fossil hunting expedition to excavate the bones making a full skeleton of a mastodon.

You can read about his life’s change in direction in his own words, from a lecture he gave in 1799, about the development of his Peale Museum.


Book of the Day
The Science of Leonardo: Inside the Mind of the Great Genius of the Renaissance

On 15 Apr 1452, Leonardo da Vinci was born, one of the most versatile minds of his era, and well-known to us now. He was an Italian painter, draftsman, sculptor, architect. Da Vinci was also a great engineer and inventor who designed buildings, bridges, canals, forts and war machines. He kept huge notebooks sketching his ideas. Among these, he was fascinated by birds and flying and his sketches include such fantastic designs as flying machines. These drawings demonstrate a genius for mechanical invention and insight into scientific inquiry, truly centuries ahead of their time. His greater fame lies in being one of the greatest painters of all times, best known for such paintings as the Mona Lisa and The Last Supper.

Today's book pick is: The Science of Leonardo: Inside the Mind of the Great Genius of the Renaissance, by Fritjof Capra, who provides a well-researched, profound and clear exploration of Leonardo’s scientific thought. In fact, da Vinci was as much a scientist as he was artist. These came together in his meticulous obsession with anatomy. The author holds the reader’s attention as he fills page after page with the fascinating diversity of Leonardo’s projects.
