THE COMPLETE TALES OF Jules de Grandin is dedicated to the memory of Robert E. Weinberg, who passed away in fall of 2016. Weinberg, who edited the six-volume paperback series of de Grandin stories in the 1970s, also supplied many original issues of Weird Tales magazine from his personal collection so that Seabury Quinn’s work could be carefully scanned and transcribed digitally. Without his knowledge of the material and his editorial guidance, as well as his passion for Quinn’s work over a long period of time (when admirers of the Jules de Grandin stories were often difficult to come by), this series would not have been possible, and we owe him our deepest gratitude and respect.
