Ira Moskowitz was born in Galicia, Poland in 1912, emigrating with his family to New York in 1927. He enrolled at the Art Student's League and studied there 1928-31. In 1935, he traveled to Paris and then lived until 1937 in what is now Israel. He returned in 1938 to marry artist Anna Barry in New York. The couple soon visited Taos and Santa Fe in New Mexico, returning there for extended periods until in 1944 they moved there permanently and stayed until 1949.
During this time, Moskowitz received a Guggenheim fellowship in 1943. While Moskowitz devoted much of his life to the production of Judaic art, his New Mexico period was especially productive of other work. His New Mexico art consists mostly of "Regionalist" subjects depicting both the New Mexico landscape and life within the state's three cultures. He especially focused on pueblo life. He and Anna also visited and sketched across the border in Old Mexico. While in the Southwest, Moskowitz flourished as a printmaker, yet continued to produce oils and watercolors as well.
After leaving the Southwest, printmaking remained a major part of his life and art. But his focus drastically changed as to subject. Later works of Moskowitz depict religious (Judaic) subjects primarily. These works were well received early on and Moskowitz was content to stay with them the rest of his life.
From 1963 until 1966 Moskowitz lived in Paris. He then returned in 1967 to New York City where he made his permanent home (with intermittent sojourns) until he died there in 2001. Shortly before his death, Zaplin-Lampert Gallery of Santa Fe staged a year 2000-01 exhibition of Ira's works.
