The Art of Handwriting reveals how the simple act of writing a letter in one's own hand can be an artistic act. The letters, from the collections of the Smithsonian's Archives of American Art, show that an artist might put pen to paper just as he or she would apply a line to a drawing. In the age of emails, texts, and tweets, this book explores what can be learned from the handwriting of artists such as Georgia O'Keefe, Isamu Noguchi, Willem de Kooning, Thomas Eakins, and others. For each letter, a leading authority on the artist's work will discuss how the pressure of line and sense of rhythm speak to that artist's signature style. Questions of biography also arise: Does handwriting confirm assumptions about the artist, or does it suggest a new understanding?
