Clara Louise Maass



1876 - 1901


Born:  Clara Louise Maass was born on June 28, 1876 in East Orange, NJ, the first of 10 children. Her parents, Hedwig and Robert Maass, were immigrants from Germany.


When Clara was 17, she entered the Christina Trefz Training School of Nurses at Newark German Hospital, only the fourth such nursing school at the time in New Jersey and the first in Newark. She graduated in 1895, after two years of arduous training. In 1898, at the age of 21, she was named head nurse at Newark German Hospital.

She worked as an Army nurse in Florida, Cuba, and the Philippines during the Spanish-American War. In 1900, Maass returned to Cuba at the request of Maj. William Gorgas, chief sanitation officer. There she became embroiled in a controversy over the cause of yellow fever.

A Cuban doctor, Carlos Juan Finlay, had proposed that transmission was not by personal contact, but instead through the stegomyia fasciata mosquito. The test for proof was clear: volunteers were needed to expose themselves to the infected mosquito.

Clara Maass was the only American woman to volunteer. She contracted the disease, but recovered. Then on August 14, 1901, she offered herself again; ten days later she died. With her sacrifice, Major Reed proved that the mosquito was the carrier of yellow fever.
