Cook was born on February 5, 1856, in
Salt Lake City, Utah to John and Margaretta Gratrix Cook. Her mother, Margaretta, left her father due to his stinginess and his belief in
polygamy. In 1870, Eliza, her mother, and Eliza’s sister Rebecca moved to
Sheridan, Nevada. Without a school to attend, Eliza was educated by her mother and whatever books she could find. One book, the title of which is unknown, was about home remedies and got her interested in medicine. Dr. H. W. Smith hired Cook to help nurse his wife when she had
puerperal fever. Cook’s skills impressed him so much that he hired her as his assistant. This gave her access to his medical library, where she read everything she could read. She earned her Nevada
medical license in April 1899, the first year that they were issued by the state. As a doctor, Cook performed surgeries, set broken limbs, and delivered many babies. She also worked as a pharmacist and wrote articles about health issues for magazines and medical journals. Cook was a member of the
American Woman Suffrage Association and the
Women's Christian Temperance Union. She was a founding member of the
Nevada Women’s Equal Suffrage League and was elected the inaugural vice president of the organization in October of 1895. After her term was over, she became president of the
Douglas County Equal Suffrage League, and continued to serve both organizations by circulating
petitions, writing to legislators, and publishing letters in the newspapers. She served as Vice President of the
Nevada Equal Suffrage Association. Never married, Cook resided in
Mottsville,
Carson Valley, and
Douglas County. She died on October 2, 1947 ==References==
