Abstract
Dr. Sidney Farber (Farber) was a distinguished pediatric pathologist and widely recognized pioneer of modern chemotherapy. In 1948, his influential study showed that various anti-folates, particularly 4-aminopteroylglutamic acid, also known as aminopterin, induced transient disease control in kids who had acute undifferentiated leukemia. The findings laid the basis for developing and using additional chemotherapies, individually or in combination, for treating pediatric and adult cancers. Farber also introduced actinomycin D to treat Wilms tumor in various stages. Underneath his oversight, the 'Jimmy Fund,' one of the earliest dedicated pediatric oncology centers, and the Children's Cancer Research Foundation, which subsequently evolved into the Dana-Farber Cancer Institute, was established. Farber is known as the "Founder of Pediatric Pathology" and the "Father of Modern Chemotherapy," citing his immense contributions. This article is a tribute to the great scientist Farber for his significant contributions to the scientific field and the countless individuals he has impacted.
