A professional newspaperman, Clifford Donald Simak was a major figure both in and beyond the 'Golden Age' of science fiction. Active for more than fifty years, he published some 140 short stories and (depending on how you count) at least 27 novels. The many Awards he received - three Hugos, a Nebula, a Jupiter, a Locus, an Analog, and an International Fantasy Award - to say nothing of many nominations, show that his contemporaries recognised his qualities. It is no surprise that the Science Fiction Writers of America elected him as their third SWFA Grand Master. This book considers what he achieved. CDS grew up in Grant County, Wisconsin, just south of where the Wisconsin flows into the Mississippi. Many of his tales reflect the 'Simak country' of his youth, regularly drawing on the characteristics of the residents of that area. They are high value entertainment. Some are extremely amusing. Others lead you on to explore many ideas: what does it mean to be sentient, to be human, how should/can we cope with technology, has life a purpose, and if so what, and, what about aliens?
