The tower was built for the National Life and Accident Insurance Company and served as its National Life Center until the State of Tennessee acquired it on January 3, 1994.

More than 1,000 state employees who had been assigned to numerous locations now work in the building.

[2] The building is named in honor of William R. Snodgrass, a career public servant who served as Tennessee's Comptroller of the Treasury from 1955 to 1999.

The tower was struck by lightning on August 31, 2003, which caused a firepump to turn on the sprinkler system.
