His first documentary work was a two-part series he wrote, produced and directed for PBS, Ethics in American Business with Walter Cronkite (1991). The nation’s foremost expert on Lincolniana, Mann authenticates historical documents and places American treasures with collectors, museums and public institutions.

When not geeking out, he can be found (weather permitting) walking across the Manhattan Bridge to Brooklyn.
