Frederick Sommer (September 7, 1905 – January 23, 1999), was an artist born in Angri, Italy and raised in Brazil. He earned a M.A. degree in Landscape Architecture (1927) from Cornell University where he met Frances Elisabeth Watson (September 20, 1904 – April 10, 1999) whom he married in 1928; they had no children. The Sommers moved to Tucson, Arizona in 1931 and then Prescott, Arizona in 1935. Sommer became a naturalized citizen of the United States on November 18, 1939.

Considered a master photographer, Sommer first experimented with photography in 1931 after being diagnosed with tuberculosis the year prior. Early works on paper (starting in 1931) include watercolors, and evolve to pen-and-ink or brush plus drawings of visually composed musical score. Concurrent to the works on paper, Sommer started to seriously explore the artistic possibilities of photography in 1938 when he acquired an 8×10 Century Universal Camera, eventually encompassing the genres of still life (chicken parts and assemblage), horizonless landscapes, jarred subjects, cut-paper, cliché-verre negatives and nudes. According to art critic Robert C. Morgan, Sommer's "most extravagant, subtle, majestic, and impressive photographs—comparable in many ways to the views of Yosemite Valley’s El Capitan and Half Dome by Ansel Adams—were Sommer’s seemingly infinite desert landscapes, some of which he referred to as 'constellations.'" The last artistic body of work Sommer produced (1989–1999) was collage based largely on anatomical illustrations.
