The first Doc Savage story appeared in 1933 and the series ran in pulp and later digest format into 1949. Bantam reprinted the entire series in paperback with wonderful, iconic covers starting in the 1960's. Doc was arguably the first great modern superhero with a rich background, continuity, and mythos. The characterizations were far richer than was common for the pulps; his five associates and their sometimes-auxiliary, Doc's cousin Pat, and the pets Chemistry and Habeas Corpus, all had very distinctive characteristics and their byplay was frequently more entertaining that the current adventure-of-the-month. The settings were also fascinating: Doc's Fortress of Solitude, the Hidalgo Trading Company (which served as a front for his armada of vehicles), and especially the mysterious 86th floor headquarters all became familiar haunts to the reader, and the far-flung adventures took the intrepid band to exotic and richly-described locations all over the world. The adventures were always fast-paced and exciting, from the early apocalyptic world-saving extravaganzas of the early days to the latter scientific-detective style shorter works of the post-World War Two years. There were always a few points that it was difficult to believe along the way, but there were always more ups than downs, and there was never, ever a dull moment. The Doc Savage books have always been my favorite entertainments... I was always, as Johnny would say, superamalgamated!
