Among the incorporators of Kupreanof was former Petersburg Grade School Principal Harold Bergman. Kupreanof was once called West Petersburg and was a thriving community of fur farms and commercial fishermen in the early- to mid-20th century. Gradually most residents moved over to the larger, more metropolitan city of Petersburg.
Kupreanof remained a separate municipality when the Petersburg Borough incorporated, unlike the neighboring city of Petersburg. However, Kupreanof now lies inside the Petersburg Borough, whereas before, it was a home-rule city inside the unorganized Petersburg Census Area.
Robert "Bobby" Dolan was mayor of Kupreanof for over 40 years.
