Clara Maass

Clara Louise Maass (June 28, 1876 – August 24, 1901) was an American nurse who died as a result of volunteering for medical experiments to study yellow fever.[1][2]

Early life

Clara Maass was born in East Orange, New Jersey, to German immigrants Hedwig and Robert Maass. She was the oldest of nine children in a devout Lutheran family.[3] Clara's family was impoverished and to help alleviate the financial burden of one child on her family, she went to work as a "mother's helper" for a local woman while in elementary school. She did not generate any income, but was able to live and eat with her employer's family.[4]

In 1895, she became one of the first graduates of Newark German Hospital's Christina Trefz Training School for Nurses. By 1898, she had been promoted to head nurse at Newark German Hospital, where she was known for her hard work and dedication to her profession.[3]

Army service

In April 1898, during the Spanish–American War, Maass volunteered as a contract nurse for the United States Army (the Army Nurse Corps did not yet exist). She served with the Seventh U.S. Army Corps from October 1, 1898, to February 5, 1899, in Jacksonville, Florida, Savannah, Georgia, and Santiago, Cuba. She was discharged in 1899, but volunteered again to serve with the Eighth U.S. Army Corps in the Philippines from November 1899 to mid-1900.[5]

During her service with the military, she saw few battle injuries. Instead, most of her nursing duties came in providing medical aid to soldiers suffering from infectious diseases like typhoid, malaria, dengue and yellow fever. She contracted dengue in Manila, and was sent home.[5]

Yellow fever studies

Shortly after finishing her second assignment with the army, Maass returned to Cuba in October 1900 after being summoned by William Gorgas, who was working with the U.S. Army's Yellow Fever Commission. The commission, headed by Major Walter Reed, was established during the post-war occupation of Cuba in order to investigate yellow fever, which was endemic in Cuba. One of the commission's goals was to determine how the disease was spread: by mosquito bites or by contact with contaminated objects.[5]

The commission recruited human subjects because they did not know of any animals that could contract yellow fever. In the first recorded instance of informed consent in human experiments, volunteers were told that participation in the studies might cause their deaths. As an incentive, volunteers were paid US$100 (approximately $3,000 today), with an additional $100 if the volunteer became ill.[5]

In March 1901, Maass volunteered to be bitten by a Culex fasciata mosquito (now called Aedes aegypti) that had been allowed to feed on yellow fever patients. By this time, the researchers were certain that mosquitoes were the route of transmission, but lacked the scientific evidence to prove it because some volunteers who were bitten remained healthy. Maass continued to volunteer for experiments.[3]

Death

On August 14, 1901, Maass allowed herself to be bitten by infected mosquitoes for the second time. Researchers were hoping to show that her earlier case of yellow fever was sufficient to immunize her against the disease. Unfortunately, this was not the case. Maass once again became ill with yellow fever on August 18 and died on August 24. Her death roused public sentiment and put an end to yellow fever experiments on human beings.[3]

Maass was buried in Colon Cemetery in Havana with military honors. Her body was moved to Fairmount Cemetery in Newark, New Jersey on February 20, 1902.[6]
