William Van Alen hid a 185-foot steel spire inside the Chrysler Building's own crown, assembled in secret. His rival H. Craig Severance had designed 40 Wall Street two feet taller - thinking he'd win. Van Alen raised the hidden spire through the roof in 90 minutes on October 23, 1929. The Chrysler Building jumped to 1,046 feet, the first skyscraper to top 1,000 feet. It held the record for 11 months.
