Just one month after assuming the title of “World’s Oldest Man,” Alexander Imich, passed at the age of 111 in Manhattan on Sunday.

According to a report from the New York Times, the scholar and retired chemist, who was named the “oldest living” male by the Gerontology Research Group of Torrance, California, last month, died “peacefully” at a senior residence at West End Avenue and 74th Street in Manhattan.

On May 8, Imich was awarded his certified by the Guinness World Records certificate and title of “Oldest Living Man.” Imich was reportedly 111 years and 93 days old at the time of his death.

Imich was born in present-day Czestochowa, Poland, in 1903, before fleeing the country due to the rise of Nazism in 1939 and surviving a Soviet Gulag. In 1951, Imich immigrated to the United States with his wife, Wela, settling in Manhattan before her passing in 1986.

“I don’t know, I simply didn’t die earlier,” Imich said of his supercentenarian age to NBC in May. “I have no idea how this happened.” Imich previously credited his genes as the source of his long life.  

Despite his title, Imich is survived by at least 65 older females, Time Magazine reports. The title of World’s Oldest Woman is currently held by 116-year-old Misao Okawa of Japan.
