MATTESON, Ill., Feb. 3 (UPI) -- Jane Ising, one of the world's oldest women, died in an Illinois nursing home on her 110th birthday, family members said.
The birthday party planned at the the Applewood Nursing and Rehabilitation Center in Matteson, Ill., was held anyway Thursday as a celebration of her life, family members told the Chicago Tribune.
Ising, who died in her sleep early Thursday, was one of fewer than 100 "super-centenarians" worldwide, the Gerontology Research Group said.
Born Johannah Ehmer on Feb. 2, 1902, in Berlin, Ising received a doctoral degree in economics and taught in Germany before working as a researcher at Berlin University. She and her husband, physicist Ernest Ising, fled the Nazis in 1938 and stayed in Luxembourg until the end of World War II, when they emigrated to the United States.
Thomas Ising, 72, said his parents spent most of their lives in Peoria, Ill. Ernest Ising taught physics at Bradley University and Jane taught economics and German in the public school system. Her husband died in 1998 at age 98.
Ising moved to Matteson in 2007. She is survived by her son, two grandchildren and five great-grandchildren, the newspaper said.
