CEDAR RAPIDS — The man known around Cedar Rapids as “Mr. History” soon will take perhaps his most direct role to date preserving the city’s past. Mark Stoffer Hunter will partner with developer Hobart Hisoric Restoration to create History Connect, slated to begin offering services May 28, after resigning in late April from The History Center after on-and-off work there since 2000.Through the new Hobart subsidiary, Stoffer Hunter will assist with the research and development of historical initiatives and partner with developers working to restore historical sites — responsibilities he said were familiar but now are on a more formal level.“I’m stepping up my game a little bit,” laughed Stoffer Hunter, 53, when reached by phone Thursday.
