Helmuth Naumer Sr. (born 1907 in Reutlingen, Germany; died 16 June 1990) was a German artist. He painted subjects throughout the United States and around the world but New Mexico was his favourite subject. Naumer studied art in Germany and in 1926, he moved to the United States to experience the West that he had read about in novels of cowboy life. He attended the Frank Wiggins Trade School and the Otis Art Institute in Los Angeles and then joined the Merchant Marine. After six years at sea, Naumer moved to Santa Fe, New Mexico in 1932. There he began to work in pastels.
In 1933, during the Great Depression, the Civilian Conservation Corps constructed various park buildings in Frijoles Canyon in Bandelier National Monument including a visitor centre as part of the federal Works Progress Administration's employment program. Naumer together with Pablita Velarde and E. J. Austin were commissioned by the National Park Service to create works for the newly built visitor centre exhibits. Naumer created a series of paintings showing scenes in Bandelier National Monument and nearby pueblos. He produced fourteen pastel artworks from 1935-1936 for Bandelier National Monument, works of art which remain in the Bandelier museum collections.
Although Naumer also worked in oils and watercolors, pastels were his preferred medium. He believed they allowed him to capture "the fleeting effects of the sky and water and our own New Mexico landscapes with fast changing colors sweeping rapidly across it, for there are hundreds of different colors and shades, so one loses no time in mixing colors as in oil."
Naumer was a professional artist recognized as one of the major painters of the Santa Fe school. Describing his work in a 1959 pamphlet, he said "though born in Europe and having lived in many places in the world, coming to the Southwest was like coming home. Here I found peace and beauty and these I try to paint." His work is held in such museums as the New Mexico Museum of Art and the Panhandle-Plains Historical Museum
