Selman Abraham Waksman
Selman Abraham Waksman (July 22, 1888 – August 16, 1973) was an American biochemist and microbiologist whose research into organic substances—largely into organisms that live in soil—and their decomposition promoted the discovery of Streptomycin, and several other antibiotics. A professor of biochemistry and microbiology at Rutgers University for four decades, his work led to the discovery of over twenty antibiotics (a word which he coined) and procedures that have led to the development of many others. The proceeds earned from the licensing of his patents funded a foundation for microbiological research, which established the Waksman Institute of Microbiology located on Rutgers University's Busch Campus in Piscataway, New Jersey (USA). In 1952 he was awarded the Nobel Prize in Physiology or Medicine in recognition "for his discovery of "streptomycin" the first antibiotic active against tuberculosis."
In 2005 Selman Waksman was designated an ACS National Historical Chemical Landmark in recognition of the significant work of his lab in isolating more than fifteen antibiotics, including streptomycin, which was the first effective treatment for tuberculosis.
Biography
Selman Waksman was born on July 22, 1888 to Jewish parents in Nova Pryluka, Podolia Governorate in the Russian Empire, now Vinnytsia Oblast, Ukraine. He immigrated to the United States in 1910, shortly after receiving his matriculation diploma from the Fifth Gymnasium in Odessa, and became a naturalised American citizen six years later.
Waksman attended Rutgers College (now Rutgers University), where he was graduated in 1915 with a Bachelor of Science (B.Sc.) in Agriculture. He continued his studies at Rutgers, receiving a Master of Science (M.Sc.) the following year. During his graduate study, he worked under J. G. Lipman at the New Jersey Agricultural Experiment Station at Rutgers performing research in soil bacteriology. Waksman was then appointed as Research Fellow at the University of California, Berkeley from where he was awarded his Doctor of Philosophy (Ph.D.) in Biochemistry in 1918.
Later he joined the faculty at Rutgers University in the Department of Biochemistry and Microbiology. It was at Rutgers that Waksman's team discovered several antibiotics, including actinomycin, clavacin, streptothricin, streptomycin, grisein, neomycin, fradicin, candicidin, candidin, and others. Two of these, streptomycin and neomycin, have found extensive application in the treatment of numerous infectious diseases. Streptomycin was the first antibiotic that could be used to cure the disease tuberculosis. Waksman coined the term antibiotics.
Many awards and honors were showered on Waksman after 1940, most notably the Nobel Prize in 1952; the Star of the Rising Sun, bestowed on him by the emperor of Japan, and the rank of Commandeur in the French Légion d'honneur.
Selman Waksman died on August 16, 1973 and was interred at the Crowell Cemetery in Woods Hole, Barnstable County, Massachusetts. His tombstone is inscribed simply as Selman Abraham Waksman: Scientist, followed by his dates of birth and death, and the phrase "The earth will open and bring forth salvation", which is a reference to Isaiah 45:8.
Streptomycin
Waksman had been studying the Streptomyces family of organism since his college student days and had, for a time, been studying the organism Streptomyces griseus. Streptomycin was isolated from S. griseus and found effective against tuberculosis by one of Waksman's graduate students, Albert Schatz.
Controversy
The details and credit for the discovery of streptomycin and its usefulness as an antibiotic were strongly contested by Schatz, eventually leading to litigation. Waksman and Rutgers settled out of court with Schatz, resulting in financial remuneration and entitlement to "legal and scientific credit as co-discoverer of streptomycin."
Neomycin
Neomycin is derived from actinomycetes and was discovered by Waksman and Hubert A. Lechevalier, one of Waksman's graduate students. The discovery was published in the journal Science.
Nobel Prize
Waksman was awarded the Nobel Prize in 1952 for "for his discovery of streptomycin, the first antibiotic effective against tuberculosis" though it is understood that the Nobel Prize was awarded not only for the discovery of streptomycin but also for the development of the methods and techniques that led up to its discovery, and the discovery of many other antibiotics.
Waksman created the Waksman Foundation for Microbiology in 1951 using half of his personal patent royalties. At a meeting of the board of Trustees of the Foundation, held in July 1951 he urged the building of a facility for work in microbiology, named the Waksman Institute of Microbiology, which is located on the Busch campus of Rutgers University in Piscataway, New Jersey. The Selman A. Waksman Award in Microbiology of the National Academy of Sciences is given in his honor.
Publications
Selman Waksman was author or co-author of over 400 scientific papers, as well as twenty-eight books and 14 scientific pamphlets.
Enzymes (1926)
Humus: origin, chemical composition, and importance in nature (1936, 1938)
Principles of Soil Microbiology (1938)
My Life with the Microbes (1954) (an autobiography)
