Dutch was the language of her childhood home, and De Vries did not learn English until she attended grammar school. After completing the sixth grade, De Vries was sent to work in silk mills.

In 1925, she matriculated to a nurses training program at New Rochelle HospitalTraining School for Nurses in New York. After receiving her nursing degree, De Vries married Wilbur Fuhr.

Life Work
De Vries is remembered for her work as a public health nurse in Mexico. Before living in Mexico, De Vries joined the Communist Party in 1935. Two years later, in 1937, she volunteered to travel to Spain with the Medical Bureau to Aid Spanish Democracy, which provided medical care for the international brigades and Spanish anti-fascist fighters during the Spanish Civil War. She was at the Madrid front in February 1937 during the Battle of Jarama. "Within four hours after the battle had begun, we had 93 wounded. Our hospital was equipped for fifty," writes De Vries of the battle in her memoirs. Later, she was sent to Villa Paz where she oversaw the administration of the hospital of Castillejo. Recounting her efforts to sustain the running of the hospital, De Vries managed to convince the male soldiers to participate in the chores needed to free nursing hands, including dish-washing, scrubbing, washing, digging latrines. Her memoirs describe her time at Castillejo as revolutionary in the co-operative that was being formed. Moreover, she writes of the concerns of farmers and soldiers to their own futures, which led to the opening of new clinics and even new trenches that included special sections for classroom work. As such, she remembers this as a time of idealism: "This was a crusade for the freedom of man." Upon her return to the United States, De Vries embarked on a fundraising lecture tour. When the lecture tour concluded, De Vries worked as a nurse and public health educator. She held positions with the San Miguel County Public Health Demonstration Unit in New Mexico, the Department of Public Health in Puerto Rico, and the Agricultural Workers Health and Medical Association of Southern California. De Vries moved to Mexico in 1949. She was the director of health education for the Comisión del Papaloapan serving the indigenous communities in the Papaloapan River Valley in the states of Oaxaca and Veracruz. She was also an instructor of public health at the Universidad Veracruzana in Jalapa, Veracruz, and established summer schools for foreign students both there and at the Universidad de Morelos in Cuernavaca. In 1962, a presidential decree granted De Vries Mexican citizenship
