Morrie Markoff, a supercentenarian blogger and scrap-metal sculptor who was believed to be the oldest man in the United States and whose brain has been donated for research on what is known as super-aging, died on June 3 at his home in downtown Los Angeles. He was 110. He had two strokes in recent weeks, his daughter, Judith Markoff Hansen, said in confirming his death. People who live to be 110 or older are considered supercentenarians, and the Gerontology Research Group, in Los Angeles, lists more than 150 of them around the world. Mr. Markoff, who was born in New York City on Jan. 11, 1914, six months before World War I began, joined the club this year and was regarded as the oldest living man in the United States after the death in January of Francis Zouein, at 113, in California.
