The unique design of the John Handcock Center was developed by the structural civil engineer Fazlur Khan and chief architect Bruce Graham. The majority of construction of the building was completed by Tishman Construction Co.

The project began in 1964 as a plan by Jerry Wolman to build the tallest building in the world. Wolman initiated the development and construction began in 1965. However, construction was delayed in 1967 due to a flaw in the way that concrete was being poured. Wolman had to back out of the project due to the financial strain of the delay and John Hancock Mutual Life Insurance Co. took up the financing of the project. The building was completed in 1969 and was named after the company that financed the project.
