Episodes I through III of Star Wars detail the life of Anakin Skywalker, including his manipulation at the hands of Darth Sidious. Since Anakin was apparently a side effect of work done by Darth Sidious' master, Darth Plagueis, was Darth Sidious aware of Anakin's existence when he still lived on Tatooine?
1 Answer
No.
From the plot summary of Star Wars : Darth Plagueis novel on Wookieepedia:
As the novel comes to a close during the events of The Phantom Menace, Sidious and Plagueis learn that a young boy named Anakin Skywalker, a former slave found by Qui-Gon Jinn on Tatooine, had been born of the Force. They discern that this is most likely due to Plagueis's experiment of creating life through the Force that he had commenced about a decade earlier.
