Who was Harry Blackmun? The short answer is that he was an Associate Justice of the United Supreme Court and the author of Roe v. Wade. The slightly longer answer can be found in the 2005 national bestseller Becoming Justice Blackmun: Harry Blackmun’s Supreme Court Journey. The book relies exclusively on the extensive collection of personal and official papers donated in Blackmun’s will to the Library of Congress. He left a long paper trail of his life that Linda Greenhouse weaves into a readable narrative and interesting introduction to Justice Blackmun.
