Chicago’s Willis Tower lights are purple during the first week of November for National Alzheimer’s Disease Awareness Month.
The building’s architect, Bruce Graham, died of Alzheimer’s disease this year.
“It is not a secret that Bruce Graham was a magnificent architect,” said Erna Colborn, president and CEO of the Alzheimer’s Association of Greater Illinois, in a news release. “Mr. Graham helped shape the city skyline of Chicago designing such buildings as the Willis Tower and The John Hancock Center. He undoubtedly left his mark on the Windy City. He also battled Alzheimer’s disease, a disease which affects more than 500,000 Illinoisans.”
