Gladia Delmarre, later known as Gladia Solaria, Gladia Gremionis, or, more commonly, simply Gladia, is a character from Isaac Asimov's Robot series. She first appears in the book The Naked Sun, which is set on Solaria, a planet which has ten thousand robots for every human being and where most people cannot tolerate the personal presence of other people. When Gladia's husband is murdered, she is the chief suspect because he would not have allowed anyone else near him. After Elijah Baley solves the murder case, finding out (though not revealing) that she indeed was the killer though not responsible, Gladia moves to Aurora, as Dr. Han Fastolfe protegé. This is apparently recommended by Baley, who had noticed that Gladia has a desire for human company which is completely out of place on Solar
