Abraham Horwitz, a native of Chile, was graduated in 1936 from the University of Chile medical school. In a recent article about him, it is noted that he chose to study medicine and infectious diseases because of his family's experience as émigrés from Russia (adapted from "Pan American Health Organization Leader Abraham Horwitz, 89, Dies" from the washingtonpost.com). His parents were denied access into the United States and, ultimately, ended up in Chile because of an eye infection of his mother. After medical school he joined the Pan American Health Organization (PAHO) and specialized in infectious diseases and public health.
In the early 1940s, Horwitz was a key player in the treatment of meningitis using sulfas, which greatly reduced the death rate. In 1944 Horwitz received his Master of Public Health from the Johns Hopkins School of Public Health. He also was appointed the director of the University of Chile's School of Public Health. During the 1950s he worked for the Pan American Health Organization in Chile on smallpox eradication.
In 1958 he was elected to be the director of the Pan American Health Organization, a post, in which he served until 1975. Over the 17 years as director of PAHO, Horwitz was the only director to be elected and re-elected four times. He was dedicated to the health of in the Americas. He devoted much of his research to nutrition.
