Abraham "Bram" Stoker (1847-1910) was an Irish writer and bureaucrat, notable in his time as Sir Henry Irving's assistant and theatre-manager. Stoker is probably best remembered today as the writer of several horror novels, notably Dracula. This book is arguably the source for much of the modern vampire myth, and notably features a vampire-hunter, Van Helsing, to whom Stoker gave his own first name.
Philip José Farmer mentions a Van Helsing, presumably some relative of Stoker's, in Doc Savage: His Apocalyptic Life.
Kim Newman used Stoker's novel Jewel of the Seven Stars, about Egyptian mummies, as the inspiration for his own episodic novel Seven Stars, which has several crossovers of interest to the Wold Newton scholar.
