Isabella Garnett was born in Evanston in 1872 and received a nursing degree from Provident Hospital and Nurses Training School in 1895. She later graduated with a medical degree from the College of Physicians and Surgeons (now the University of Illinois College of Medicine) in 1901, making her one of the first female African American physicians in Illinois.

The Illinois Woman Suffrage Association (IWSA) was founded in 1869 and in the early 20th century changed its name to Illinois Equal Suffrage Association (IESA). After more than 40 years of active campaigning, Illinois women gained the right to vote in many statewide races in 1913.
