Question: Which American artist's studios, known for New Mexico landscapes, is part of the National Trust for Historic Preservation?
Context: Preservation, the magazine of the National Trust for Historic Preservation, launched in 1952 as "Historic Preservation."  In 1998, the magazine won a National Magazine Award for General Excellence under its then-editor, Robert S. Wilson.  The magazine's launching point is architecture, but it is also, as the judges of the National Magazine Award write, about "politics, art, history, places, and people … "Preservation" tells the stories of extraordinary buildings and sites all over the world."  The headquarters of the magazine is in Washington DC. Kirkland Museum of Fine & Decorative Art is an art museum in Denver, Colorado.  The museum houses three principal collections and includes the original studio and art school building of artist Vance Kirkland (1904–1981).  The museum is temporarily closed to visitors to relocate to a new building at 12th Avenue and Bannock Street, opening early 2018.  The 1911 Arts & Crafts style studio building is listed as a member of Historic Artists’ Homes and Studios, a program of the National Trust for Historic Preservation, along with the homes and studios of Jackson Pollock/Lee Krasner, Charles Russell, Georgia O'Keeffe, Thomas Hart Benton, Charles Burchfield, N. C. Wyeth, Grant Wood and others. Preservation Action is an American 501(c)4 non-profit historic preservation advocacy organization.  Preservation Action was created in 1974 to serve as the national grassroots lobby for historic preservation.  The organization seeks to make historic preservation a national priority by advocating to all branches of the federal government for sound preservation policy and programs through a grassroots constituency of hundreds of members from throughout the United States.  Preservation Action provides information and training, and encourages direct contact with elected representatives, with National Historic Preservation Advocacy Week being the highlight of advocacy and outreach efforts each year. This list of African American Historic Places in Texas is based on a book by the National Park Service, The Preservation Press, the National Trust for Historic Preservation, and the National Conference of State Historic Preservation Officers. The National Trust for Historic Preservation (NTHP) is a privately funded, nonprofit organization based in Washington, D.C., that works in the field of historic preservation in the United States.  The member-supported organization was founded in 1949 by congressional charter to support the preservation of America’s diverse historic buildings, neighborhoods, and heritage through its programs, resources, and advocacy. Georgia Totto O'Keeffe (November 15, 1887 – March 6, 1986) was an American artist.  She was best known for her paintings of enlarged flowers, New York skyscrapers, and New Mexico landscapes.  O'Keeffe has been recognized as the "Mother of American modernism". Woodlawn Plantation is a historic house located in Fairfax County, Virginia.  Originally a part of Mount Vernon, George Washington's historic plantation estate, it was subdivided in the 19th century by abolitionists to demonstrate the viability of a free labor system.  The address is now 9000 Richmond Highway, Alexandria, Virginia, but due to expansion of Fort Belvoir and reconstruction of historic Route 1, access is via Woodlawn Road slightly south of Jeff Todd Way/State Route 235.  The house is a designated National Historic Landmark, primarily for its association with the Washington family, but also for the role it played in the historic preservation movement.  It is now a museum property owned and managed by the National Trust for Historic Preservation. The National Historic Preservation Act of 1966 (NHPA) envisioned a funding source to provide states with matching funds to implement the Act.  The Act was to be implemented through partnerships with states, Indian Tribes, Native Hawaiians, local governments, nonprofit organizations, and the private sector.  It brought forth state programs to implement much of the Act; a National Register of Historic Places encompassing a wide range of sites and structures deemed historic; partnerships at all levels of government; incentives; assistance; and reviews.  The NHPA endorsed the use of federal financial support for the national preservation program and called for two basic categories of assistance, both of which provide funding, rather than technical assistance, for historic preservation projects and to individuals for the preservation of properties listed in the National Register of Historic Places.  Since enactment in 1966, repeated efforts to fund the HPF was realized after a 10-year campaign when consistent funding was authorized on September 28, 1976, through Public Law 94-422.  The law amended the National Historic Preservation Act to establish a funding source known as the Historic Preservation Fund for a historic preservation grant program to provide assistance to non-federal entities. The Farnsworth House was designed and constructed by Ludwig Mies van der Rohe between 1945 and 1951.  It is a one-room weekend retreat in a once-rural setting, located 55 miles (89 km) southwest of Chicago's downtown on a 60-acre (24 ha) estate site, adjoining the Fox River, south of the city of Plano, Illinois.  The steel and glass house was commissioned by Dr. Edith Farnsworth, a prominent Chicago nephrologist, as a place where she could engage in her hobbies — playing the violin, translating poetry, and enjoying nature.  Mies created a 1,500-square-foot (140 m) house that is widely recognized as an iconic masterpiece of International Style of architecture.  The home was designated a National Historic Landmark in 2006, after joining the National Register of Historic Places in 2004.  The house is currently owned and operated as a historic house museum by the historic preservation group, National Trust for Historic Preservation. A national trust is an organisation dedicated to preserving the cultural heritage of a particular geographic region.  Although the focus of a national trust may vary by region, the principal role is to ensure the preservation of historically significant items, and to conserve areas of natural beauty.  National trusts generally operate as private non-profit organizations.  The first such trust organisation, The Trustees of Reservations, originated in 1890 as a regional group serving the state of Massachusetts, USA.  The first national trust, the National Trust for Places of Historic Interest or Natural Beauty, was founded in England in 1895 and operates as a charitable organisation serving England, Wales and Northern Ireland (it is commonly known in the UK as the National Trust).  Other national trusts have since been set up around the world.
