Northern Trust Corp
A financial holding company that helps the world's biggest investors keep money safe, Northern Trust provides custody, fund administration, and asset management to institutions plus wealth management for wealthy families. Founded in Chicago in 1889 by banker Byron Laflin Smith, it began in a single room in the Rookery Building after friends kept asking him for estate-planning help. The name was chosen to signal discipline, reliability, and stability.
