Given the question: Given the following context:  On returning to London, Moore undertook a seven-year teaching post at the Royal College of Art. He was required to work two days a week, which allowed him time to spend on his own work. His first public commission, West Wind (1928–29), was one of the eight reliefs of the 'four winds' high on the walls of London Underground's headquarters at 55 Broadway. The other 'winds' were carved by contemporary sculptors including Eric Gill with the ground-level pieces provided by Epstein.  1928 saw Moore's first solo exhibition, held at the Warren Gallery in London.  In July 1929, Moore married Irina Radetsky, a painting student at the Royal College. Irina was born in Kiev in 1907 to Ukrainian–Polish parents. Her father did not return from the Russian Revolution and her mother was evacuated to Paris where she married a British army officer. Irina was smuggled to Paris a year later and went to school there until she was 16, after which she was sent to live with her stepfather's relatives in Buckinghamshire. Irina found security in her marriage to Moore and was soon posing for him. Shortly after they married, the couple moved to a studio in Hampstead at 11a Parkhill Road NW3, joining a small colony of avant-garde artists who were taking root there. Shortly afterward, Hepworth and her second husband Ben Nicholson moved into a studio around the corner from Moore, while Naum Gabo, Roland Penrose, Cecil Stephenson and the art critic Herbert Read also lived in the area (Read referred to the area as "a nest of gentle artists"). This led to a rapid cross-fertilization of ideas that Read would publicise, helping to raise Moore's public profile. The area was also a stopping-off point for many refugee artists, architects and designers from continental Europe en route to America—some of whom would later commission works from Moore.  answer the following question:  What is the last name of the person that got married to the woman who was smuggled to Paris as a teenager?
The answer is:
Moore
