Phoebus Levene: The Pioneer of Nucleic Acid Research

Phoebus Levene was a Russian-born American biochemist who revolutionized the field of nucleic acid research, characterizing the different forms of nucleic acid, DNA, and RNA. He is renowned for identifying the components of DNA, including adenine, guanine, thymine, cytosine, deoxyribose, and a phosphate group, which paved the way for groundbreaking discoveries in genetics and molecular biology.

Early Life and Education

Born as Fishel Rostropovich Levin on February 25, 1869, in the town ofagar, Lithuania, then part of the Russian Empire, Levene grew up in St. Petersburg. He studied medicine at the Imperial Military Medical Academy, graduating in 1891, and developed an interest in biochemistry.

Emigration to the United States

In 1893, Levene and his family emigrated to the United States due to anti-Semitic pogroms in Russia. He practiced medicine in New York City and pursued his passion for biochemical research, publishing papers on the chemical structure of sugars.

Research Career

In 1896, Levene was appointed as an Associate in the Pathological Institute of the New York State Hospitals. During his tenure, he worked with prominent chemists, including Albrecht Kossel and Emil Fischer, who were experts in proteins.

In 1905, Levene became the head of the biochemical laboratory at the Rockefeller Institute of Medical Research, where he spent the rest of his career. It was during this period that he made his most significant contributions to the field of nucleic acid research.
