Selman Waksman

Selman Waksman is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Selman Waksman rather than just read about it. In short: Selman Abraham Waksman (July 22 [O.S. July 8] 1888 – August 16, 1973) was a Russian-born American inventor, biochemist and microbiologist, whose research into the decomposition of organisms that live in soil enabled the discovery of streptomycin and several other antibiotics.

Key takeaways

  • Selman Waksman belongs to chemistry; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Selman Waksman to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Selman Waksman from memory before moving on to harder problems.

Reference excerpt

Selman Abraham Waksman (July 22 [O.S. July 8] 1888 – August 16, 1973) was a Russian-born American inventor, biochemist and microbiologist, whose research into the decomposition of organisms that live in soil enabled the discovery of streptomycin and several other antibiotics. For his work he won the 1952 Nobel Prize in Physiology or Medicine. Waksman emigrated to the United States in 1910 and became a naturalized U.S. citizen in 1916. A professor of biochemistry and microbiology at Rutgers University for four decades, he discovered several antibiotics (and introduced the modern sense of that word to name them), and he introduced 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 at the Rutgers University Busch Campus in Piscataway, New Jersey (USA). After receiving the Nobel Prize, Waksman and his foundation later were sued by Albert Schatz, one of his Ph.D. students and the discoverer of streptomycin, for minimizing Schatz's role in the discovery. In 2005, Waksman was granted an ACS National Historic Chemical Landmark in recognition of the significant work of his lab in isolating more than 15 antibiotics, including streptomycin, which was the first effective treatment for tuberculosis.

Early life and education Selman Waksman was born on July 22 [O.S. July 8] 1888, to Jewish parents in Novaya Priluka, in Kiev Governorate of the Russian Empire (present-day Vinnytsia Oblast, Ukraine). He was the son of Fradia (London) and Jacob Waksman. In 1910, shortly after receiving his diploma from the Fifth Gymnasium in Odessa, he immigrated to the United States and became a naturalized American citizen in 1916. Waksman attended Rutgers College (now Rutgers University), where he graduated in 1915 with a Bachelor of Science in agriculture. He continued his studies at Rutgers, receiving a Master of Science the following year, in 1916. 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 spent some months in 1915–1916 at the United States Department of Agriculture in Washington, DC under Charles Thom, studying soil fungi. He was appointed as a research fellow at the University of California, Berkeley, and in 1918 he was awarded his doctor of philosophy in biochemistry.

Career He joined the faculty at Rutgers University in the Department of Biochemistry and Microbiology. At Rutgers, Waksman's team discovered several antibiotics, including actinomycin, clavacin, streptothricin, streptomycin, grisein, neomycin, fradicin, candicidin, candidin. Waksman co-discovered streptomycin with Albert Schatz. Streptomycin was the first effective drug against gram-negative bacteria and the first antibiotic used to cure tuberculosis. Waksman is credited with coining the term antibiotics to describe antibacterials derived from other living organisms, for example penicillin, though the term was used by the French dermatologist François Henri Hallopeau, in 1871 to describe a substance opposed to the development of life. In 1931, Waksman organized the division of Marine Bacteriology at the Woods Hole Oceanographic Institution (WHOI) in addition to his task at Rutgers. He was appointed a marine bacteriologist there and served until 1942. He was elected a trustee at WHOI and finally a Life Trustee. In 1951, using half of his patent royalties, Waksman created the Waksman Foundation for Microbiology. 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 foundation's first president, Waksman, was succeeded in this position by his son, Byron H. Waksman, from 1970 to 2000.

Research

Streptomycin

Waksman had been studying the Streptomyces family of organisms 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. These results were later confirmed by Elizabeth Bugie Gregory, whose name was also published on "Streptomycin, a Substance Exhibiting Antibiotic Activity Against Gram-Positive and Gram-Negative Bacteria" with Schatz and Waksman. However, Bugie's name was not on the second key paper in 1944, which was regarding the efficacy of streptomycin against tuberculosis in test tubes, as Schatz claimed Bugie was not involved with the experiment. Bugie was also not given credit for her work on streptomycin, nor was she listed on the patent proposal, as she signed an affidavit stating that she did not have any contribution in discovering streptomycin. This was submitted under an attorney of the Rutgers Research and Endowment Foundation.

Worked examples

Example 1 — a first encounter with Selman Waksman

Start with the simplest possible case. Write down what Selman Waksman claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Selman Waksman before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Selman Waksman ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Selman Waksman

In research
Selman Waksman appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Selman Waksman in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Selman Waksman is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1888 births, 1973 deaths, 20th-century American Jews, so understanding it makes those chapters shorter.
In everyday life
Look for Selman Waksman outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
