During the Battle of Manhattan, Annabeth Chase activated a statue of William H. Seward in Madison Square Park. It was the first statue she activated. It was a celestial bronze statue on a red marble pedestal. The William Seward statue was sitting on a chair, legs crossed, wearing an old-fashioned suit,—Abraham Lincoln style—a bow tie, and long coattails. Books were piled under his chair, and he held a writing quill in one hand, big metal sheet of parchment in the other. 
The statue was one of many that Daedalus had created, to either attack or defend the Olympian gods, depending on which he needed to do to survive. He continued waking the other automatons as he was instructed to do.
- Due to Percy Jackson's dyslexia in The Last Olympian, he calls him William H. Steward.
- Percy suggests to Annabeth Chase that they call the statue "Bill" being short for William.
- The town of Seward, Alaska is named after him.
