Mabel Isabel Wilcox was a pioneering nurse on the island of Kauai. She served with the Red Cross in Europe during World War I, and was decorated by Elisabeth of Bavaria, Queen of Belgium and by the Mayor of Le Havre. She was instrumental in instituting public nursing services on Kauai and in getting a hospital built on the island.
She received her early education at home from a private instructor, transferring later to Punahou School on Oahu, followed by three years at Oakland High School in California, completing her basic education at the college preparatory Dana Hall School in Massachusetts. Her parents discouraged her from a career in nursing, but she persisted in pursuing her profession at Johns Hopkins School of Nursing, receiving her RN degree in 1911. According to Johns Hopkins, she was the first Hawaii resident to graduate from the school. Upon graduation, she remained in New York for several years, affiliated with the Buffalo Red Cross War Relief organization. In 1915, she returned home to Kauai as an employee of the Territorial Board of Health. Instituting the island's first public nursing services, she was influential in raising funds and getting the territorial legislature to allocate land to build the Samuel Mahelona Memorial Hospital at Kapaa.
With the outbreak of World War I, Johns Hopkins pediatrician Edwards A. Park, working with the American Red Cross Belgian Commission, headed the Children's Hospital in Le Havre as a facility for refugee Belgian children. He appointed Mabel as head nurse in supervision over 15 other nurses, among whom was Ethel Moseley Damon of Honolulu. They provided medical care and a safe haven for the children, often putting themselves in harm's way behind enemy lines to assist refugee women. In recognition of their war-time services, Mabel and Ethel were decorated with the Queen Elisabeth Medal by the Queen Elisabeth of Belgium and the Bronze Medal of the City of Le Havre by the Mayor of Le Havre.
Postwar career
Returning home to Kauai, she became the trustee and treasurer of Samuel Mahelona Memorial Hospital, and a probation officer of the Kauai County Juvenile Court.

She died at home on December 28, 1978, and is buried on the island of Kauai.
