The oldest American person has died at her Massachusetts home at age 113. Goldie Michelson was a month short of her 114th birthday.

Los Angeles-based Gerontology Research Group senior consultant Robert Young said Michelson died Friday. He said she'd been "very frail and confined to bed" and hadn't been seen in public for a long time.

Michelson was born in Elizabethgrad, Russia, in 1902 and moved to the United States when she was a child. She lived in Worcester, 50 miles west of Boston.

The Callahan Fay & Caswell Funeral Home said Michelson graduated from Brown University. It said she had a lifelong interest in theater and even installed stage lights in her basement so children could perform there.

Young said the new oldest American is New Jersey resident Adele Dunlap, who's also 113.
