Smith, E.E. "Doc": Triplanetary
Triplanetary served as the basis for Doc Smith's classic Lensman series.
Taking a zen approach, I have added nothing to the Project Gutenberg version except to reformat the titles for each chapter. All of their included art work is included here.
Smith was a real life PhD in chemistry and is considered one of the pioneers of modern scientific scifi.
