Heinrich "Harry" Heye Tammen (March 6, 1856 — July 19, 1924) was an American journalist, publisher, and businessman.

The company sold inauthentic skookum dolls, Navajo blankets, arrowheads, and other fake Native American memorabilia.

[3][6] While working at the Windsor Hotel, Tammen met his business partner, Fredrick Gilmer Bonfils.

Tammen's life was saved by newspaper editor Polly Pry, who used her skirt to bandage the wounds.

Bonfils insisted a story be published, calling it a "Million-Dollar Bunco Ring".
