Morrie Markoff, Listed as Oldest Man in the U.S., Dies at 110

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.

As of April, the oldest living man in the world is believed to be John Alfred Tinniswood, of England, at 111, according to Guinness World Records. (Guinness lists María Branyas Morera, a California native who lives in Spain, as the oldest woman in the world, at 117.)

When Mr. Markoff heard the news of his rise to the top of the list, “He just smiled and said, ‘Well, someone’s got to be there,’” his daughter said in an interview.
