Born Emmanuel Radnitzky, Man Ray was an American artist who spent most of his career in Paris, France. Perhaps best described simply as a modernist, he was a significant contributor to both the Dada and Surrealist movements, although his ties to each were informal. Best known in the art world for his avant-garde photography, Man Ray produced major works in a variety of media and considered himself a painter above all. He was also a renowned fashion and portrait photographer.

While appreciation for Man Ray’s work beyond his fashion and portrait photography was slow in coming during his lifetime, especially in his native United States, his reputation has grown steadily in the decades since.

In 1999, ARTnews Magazine named him one of the 25 most influential artists of the 20th century, citing his groundbreaking photography as well as "his explorations of film, painting, sculpture, collage, assemblage, and prototypes of what would eventually be called performance art and conceptual art" and saying "Man Ray offered artists in all media an example of a creative intelligence that, in its 'pursuit of pleasure and liberty,'" — Man Ray’s stated guiding principles — "unlocked every door it came to and walked freely where it would."

Man Ray was born in Philadelphia, Pennsylvania (in the area known as South Philadelphia), in 1890, the eldest child of recent Russian-Jewish immigrants. The family would eventually include another son and two daughters, the youngest born shortly after they settled in the Williamsburg section of Brooklyn, New York, in 1897. In early 1912, the Radnitzky family changed their surname to Ray, a name selected by Man Ray's brother, in reaction to the ethnic discrimination and anti-Semitism prevalent at that time. Emmanuel, who was called "Manny" as a nickname, changed his first name to Man at this time, and gradually began to use Man Ray as his combined single name.

Man Ray’s father was a garment factory worker who also ran a small tailoring business out of the family home, enlisting his children from an early age. Man Ray’s mother enjoyed making the family’s clothes from her own designs and inventing patchwork items from scraps of fabric. Despite Man Ray’s desire to disassociate himself from his family background, this experience left an enduring mark on his art. Tailor's dummies, flat irons, sewing machines, needles, pins, threads, swatches of fabric, and other items related to clothing and sewing appear at every stage of his work and in almost every medium. Art historians have also noted similarity in his collage and painting techniques to those used in making clothing.

Living in New York City, influenced by what he saw at the 1913 Armory Show and in galleries showing contemporary works from Europe, Man Ray's early paintings display facets of cubism. Upon befriending Marcel Duchamp who was interested in showing movement in static paintings, his works begin to depict movement of the figures.

In 1915, Man Ray had his first solo show of paintings and drawings. His first proto-Dada object, an assemblage titled Self-Portrait, was exhibited the following year. He produced his first significant photographs in 1918.

Abandoning conventional painting, Man Ray involved himself with Dada, a radical anti-art movement, started making objects, and developed unique mechanical and photographic methods of making images. In 1920 Ray helped Duchamp make his first machine and one of the earliest examples of kinetic art, the Rotary Glass Plates composed of glass plates turned by a motor. That same year Man Ray, Katherine Dreier and Duchamp founded the Société Anonyme, an itinerant collection which in effect was the first museum of modern art in the U.S.

Ray teamed up with Duchamp to publish the one issue of New York Dada in 1920, but he soon declared, "Dada cannot live in New York", and he moved to Paris in 1921.

He soon settled in the Montparnasse quarter favored by many artists. Shortly after arriving in Paris, he met and fell in love with Kiki de Montparnasse (Alice Prin), an artists' model and celebrated character in Paris bohemian circles. Kiki was Man Ray's companion for most of the 1920s. She became the subject of some of his most famous photographic images and starred in his experimental films. In 1929 he began a love affair with the Surrealist photographer Lee Miller.

For the next 20 years in Montparnasse, Man Ray made his mark on the art of photography. Great artists of the day such as James Joyce, Gertrude Stein, Jean Cocteau and Antonin Artaud posed for his camera. With Jean Arp, Max Ernst, André Masson, Joan Miró, and Pablo Picasso, Man Ray was represented in the first Surrealist exhibition at the Galerie Pierre in Paris in 1925.

In 1934, Surrealist artist Méret Oppenheim, known for her fur-covered teacup, posed for Man Ray in what became a well-known series of photographs depicting Oppenheim nude, standing next to a printing press.

Together with Lee Miller — his photography assistant and lover — Man Ray reinvented the photographic technique of solarization. He also created a technique using photograms he called rayographs.

Later in life, Man Ray returned to the United States, having been forced to leave Paris due to the dislocations of the Second World War. He lived in Los Angeles, California from 1940 until 1951. A few days after arriving in Los Angeles, Man Ray met Juliet Browner, a trained dancer and experienced artists' model. They began living together almost immediately, and married in 1946 in a double wedding with their friends Max Ernst and Dorothea Tanning. However, he called Montparnasse home and he returned there. He died in Paris on November 18, 1976.
