Who was the author of the science fiction novel "I, Robot"?

"I, Robot" is a fixup novel of science fiction short stories or essays by American writer Isaac Asimov. The stories originally appeared in the American magazines "Super Science Stories" and "Astounding Science Fiction" between 1940 and 1950 and were then compiled into a book for stand-alone publication by Gnome Press in 1950, in an initial edition of 5,000 copies. The stories are woven together by a framing narrative in which the fictional Dr. Susan Calvin tells each story to a reporter (who serves as the narrator) in the 21st century. Although the stories can be read separately, they share a theme of the interaction of humans, robots, and morality, and when combined they tell a larger story of Asimov's fictional history of robotics.

Several of the stories feature the character of Dr. Calvin, chief robopsychologist at U.S. Robots and Mechanical Men, Inc., the major manufacturer of robots. Upon their publication in this collection, Asimov wrote a framing sequence presenting the stories as Calvin's reminiscences during an interview with her about her life's work, chiefly concerned with aberrant behaviour of robots and the use of "robopsychology" to sort out what is happening in their positronic brain. The book also contains the short story in which Asimov's Three Laws of Robotics first appear, which had large influence on later science fiction and had impact on thought on ethics of artificial intelligence as well.
