Peter Norbeck (August 27, 1870December 20, 1936) was an American politician from South Dakota.
He served one term as the ninth Governor of South Dakota and three terms as a United States Senator.
Norbeck was the first native-born Governor of South Dakota to serve in office.
He is best remembered as "Mount Rushmore's great political patron," for promoting the construction of the giant sculpture at Mount Rushmore and securing federal funding for it. 
The Mount Rushmore National Memorial is a sculpture carved into the granite face of Mount Rushmore (Lakota Sioux name: Six Grandfathers) near Keystone, South Dakota, in the United States.
Sculpted by Danish-American Gutzon Borglum and his son, Lincoln Borglum, Mount Rushmore features sculptures of the heads of four United States presidents: George Washington (1732–1799), Thomas Jefferson (1743–1826), Theodore Roosevelt (1858–1919), and Abraham Lincoln (1809–1865).
The entire memorial covers and is above sea level.
South Dakota historian Doane Robinson is credited with conceiving the idea of carving the likenesses of famous people into the Black Hills region of South Dakota in order to promote tourism in the region.
Robinson's initial idea was to sculpt the Needles; however, Gutzon Borglum rejected the Needles site because of the poor quality of the granite and strong opposition from Native American groups.
They settled on the Mount Rushmore location, which also has the advantage of facing southeast for maximum sun exposure.
Robinson wanted it to feature western heroes like Lewis and Clark, Red Cloud, and Buffalo Bill Cody, but Borglum decided the sculpture should have a more national focus and chose the four presidents whose likenesses would be carved into the mountain.
After securing federal funding through the enthusiastic sponsorship of "Mount Rushmore's great political patron," U.S.
Senator Peter Norbeck, construction on the memorial began in 1927, and the presidents' faces were completed between 1934 and 1939.
Upon Gutzon Borglum's death in March 1941, his son Lincoln Borglum took over construction.
Although the initial concept called for each president to be depicted from head to waist, lack of funding forced construction to end in late October 1941.
Mount Rushmore has become an iconic symbol of presidential greatness and has appeared in works of fiction, and has been discussed or depicted in other popular works.
It attracts nearly three million people annually.
The Rushmore farmhouse is architecturally significant as a distinctive example of a vernacular stone farmhouse.
The six-by-two-bay, -story building was constructed in two stages by Jeremiah Rushmore; a descendant of English Quakers from Long Island, whose family owned the property for more than a century.
Although the exact building date is not known, tax records and construction details indicate a late 18th-century construction date or the earlier (western) half, while Rushmore's will confirms that the later (eastern) addition was constructed before his death in 1828.
The building underwent renovations in the late 1830s or early 1840s, which probably account for the Greek Revival period trim and porch, dormers were added at a later date.
The house was constructed of uncoursed fieldstone and surmounted by a steeply pitched gable roof pierced by interior end chimneys.
The building's stone construction and long, low form with steep gables are typical of Dutch, German, and English settlement groups in the late 18th century; however, its specific framing method and spatial divisions are indicative of English building practices and may reflect the family's Long Island origins.
These differences are particularly evident in the interior of the older section, which features a jambed fireplace, more and smaller floor joists, and, originally, a compact arrangement of small rooms, all features more common to houses built by those of English descent.
When the house was doubled in size in the first quarter of the 19th century, the new eastern section was built with a basement kitchen and hall and "best room" plan on the first floor, probably reflecting Jeremiah Rushmore's increased wealth and the needs of a larger family.
It is interesting that Rushmore's will (1826, codicil 1828) specified how the spaces in the expanded house would be used after his death.
He ensured that his widow and unmarried daughter would remain in the house, according them the use of the first floor best room and two second floor bedrooms in the new section.
At the same time, his daughter was forbidden to enter the old section, now home to her brother Richard and his family.
The basement kitchen was apparently accessible to all.
Despite a number of changes, the house provides important evidence of regional architecture during the early years of the American republic and illustrates the evolution of a small farm house over time to meet the needs of a changing family.
The Rushmore property was a working farm with large orchards for over a century.
Although subdivided over time, the nominated ninety-five acre property retains an open setting and several agricultural dependencies, including an original stone smokehouse and the remains of a barn and silo, which burned in the 1960s.

In 1993, Rohrabacher and Senator Jesse Helms sponsored amendments which authorized such construction into the FRIENDSHIP Act.
The Act was signed into law by President Bill Clinton on December 17, 1993.
