History

The Large Lakes Observatory was founded in 1994, after a 1988 scientific and policy conference resulted in the formation of the "Institute for Lake Superior Research" which developed into the LLO. It moved into its present location in the Research Laboratory Building in Duluth, MN after a fire in the former Old Main campus building (now the site of Old Main Park) left the Model School building untouched. LLO moved into the Model School Building shortly thereafter. Past directors of LLO include Dr. Tom Johnson and Dr. Steve Colman. Scientific expeditions carried out by LLO scientists have visited all of the
