August Paulsen (July 29, 1871 – March 11, 1927) was a Danish-American businessman noted for his philanthropy in the states of Washington and Idaho.
However, his interest lay in the mountains of the Coeur d'Alenes district, where productive mining claims were making hard working miners rich.
Upon manually drilling a 1500-foot shaft, the partners finally exposed a high quality ore body in 1901 that proved to be the best in the district.
The Hercules mine provided a full six percent of the nation's lead, and also produced good values in silver.
Paulsen's interest in philanthropy and the civic needs of Washington and Idaho make him a notable character in the history of the Inland Pacific Northwest.
