Back when skyscrapers were a new invention, business tycoons in Pittsburgh and across the country invested in this new form of high tech to proclaim their power.

Join Mark Houser, Pittsburgh Magazine contributor and host of last year’s sellout tours of unique skyscraper rooftops, as he shares several surprising stories from his upcoming book, “MultiStories: 55 Antique Skyscrapers & the Business Tycoons Who Built Them.”

Presented by Mark Houser, a columnist and historian who frequently appears in Pittsburgh Magazine. Mark also presented the Antique Skyscrapers tour during the annual Doors Open Pittsburgh event.
