In a different domain, the journalist Hunter J. Thomson was known to type entire novels to learn the style of master novelists (http://en.wikipedia.org/wiki/Hunter_S._Thompson):

"During this time he worked briefly for Time, as a copy boy for $51 a week. While working, he used a typewriter to copy F. Scott Fitzgerald's The Great Gatsby and Ernest Hemingway's A Farewell to Arms in order to learn about the writing styles of the authors."
