John Hancock Center
John Hancock Center, also known as “Big John,” stands on prestigious North Michigan Avenue in Chicago. It is a hundred-story, tapered skyscraper designed by Bruce Graham. The exterior is clad in black anodized aluminum with tinted bronze glass.
Tall buildings have to be strong in Chicago, the “Windy City.” Big John rests on caissons that extend down to bedrock as far as 191 feet below ground. Giant bracing made of square steel tubes crisscrosses the facade and carries most of the building’s weight.
Besides the Hancock Center, Graham also designed the Sears Tower in Chicago. Born in 1925 in Colombia, South America, Graham earned a degree in architecture from the University of Pennsylvania in 1948. In 1951, he joined the firm of Skidmore, Owings, & Merrill where he became a specialist in high-rise corporate structures.
The Hancock Center opened in 1970. It contains both commercial and residential space, as well as many conveniences like a post office, shops, a supermarket, a day-care center, restaurants, health clubs, a swimming pool, and even an ice-skating rink!
In 1999, the John Hancock Center was honored with the American Institute of Architects’ 25-Year Award.
