An artist's biography will inform the reader about the artist's life and accomplishments in their career. However, to better understand the creative process scholars turn to artists' drawings and sketchbooks. The preparatory drawings of the Belgian-American artist Christo not only give incite to the finished artwork but are essential because the sales from these drawings are used to finance the monumental environmental projects for which Christo is known. When these works are seen they have such impact that the experience stays with the viewer long after the project is over. These detailed drawings such as, Wrapped Reichstag II, show the building before and after wrapping plus notes by the artists Christo and his wife, Jean-Claude, who is actively involved in the conception and creation of all of the artwork. Another artist working on environmental sculpture is Dale Chihuly. Born in Tacoma Washington in 1941, Chihuly was introduced to glass when studying interior design at the University of Washington. Chihuly is perhaps best known for his chandelier constructions made of individually blown shapes of glass and assembled on site in such locations as Venice Italy, Waterford Ireland, and the Sydney Opera House. He also has a series of small-scale sculpture inspired by the art of Japanese flower arranging called, Ikebana and a series of glass baskets. The spontaneity achieved in, Boathouse Ikebana Drawing and Burned Baskets Drawing is translated to the large-scale installations. In actuality it takes much preparation to make the work feel like it was always meant to be in a certain location. Renaissance artist Michelangelo was an accomplished draftsman. In Madonna and Child c. 1512, the artist has modeled the baby as he will be modeled in stone, although, in a reverse process. In drawing the artist plans movement, composition, color and special relationships to be translated in the finished product. Alexander Calder, an American artist best known for his mobiles, has done countless drawings and models. In this case drawing is not only preliminary but becomes part of the piece. For example, in the "Circus" series a piece of wire is "drawn" into a line and forms the finished sculpture. In Hovering Bowies, 1963, he achieves the essence of the mobiles wind blown movement, special relationships and interaction of color
