Derived from the Greek words pais, meaning child, and iatros, which means doctor or healer, a pediatrician is a medical professional who specializes in providing medical care to children. Although there are surviving manuscripts devoted to pediatrics from earlier times, it was not until the middle of the 19th century that it was recognized and developed as a new medical specialty. Known for his many contributions to the field, Abraham Jacobi is considered as the father of pediatrics. He was born in Germany where he received his medical training, but later went to the United States to practice. It was there that he opened the first children's clinic in New York.
