Developer Jerry Wolman approaches architecture firm Skidmore, Owings & Merrill (SOM) to discuss developing his parking lot on the block bounded by Michigan Avenue, Delaware Place, Seneca Street (renamed Mies van der Rohe Way in 1986), and Chestnut Street.
Chief architect Bruce Graham (right) and chief engineer Fazlur Khan (left) along with their SOM team face a huge design challenge: The footprint for the project is relatively small, but Wolman’s vision is large—an apartment tower and an office building side by side, plus a garage mandated by zoning requirements. Over lunch one day, Graham grabs a salt shaker and puts it on top of the pepper shaker. He suggests to Kahn that they stack the apartments on top of the business offices. Kahn goes to work and designs a tubular system that will hold up during high winds and earthquakes. Graham incorporates Kahn’s innovative X-beams on the exterior of the tapered structure, creating the iconic look that defines the building against the Chicago skyline. It is recognized around the world.
John Hancock Mutual Life Insurance Company, which had underwritten the project, takes title from Wolman. The Hancock Center name is adopted.
