The world's oldest man, a retired chemist and parapsychologist, has died Wednesday at the age of 111.
Imich's niece, Karen Bogen of Providence, Rhode Island, says Imich died Sunday at his home in Manhattan.
Imich, who was Jewish, was born in 1903 in a town in present-day Poland; at the time, it was part of Russia. He and his wife fled after the Nazis invaded in 1939. They eventually moved to the United States in 1951. His wife died in 1986.
In news reports, Imich has said in the past that his good genes and healthy lifestyle contributed to his longevity.
