In 1965, Stephanie Kwolek made an unexpected discovery that led to the creation of synthetic fibers so strong, not even steel bullets could penetrate them.

​

That discovery made way for Kwolek’s invention of industrial fibers that today protect and save thousands of lives.

​

Most notable among these is Kevlar®, a heat-resistant material that’s five times stronger than steel, but lighter than fiberglass.

Norbert Rillieux pioneered an important sugar processing with the invention of the multiple effect evaporator.

​

Rillieux’s invention made it possible to produce sugar at a lower cost and with reduced man power.

​

The Rillieux evaporator is still used today in sugar production in addition to the production of condensed milk, soap, and glue.

  • Agnes Pockels discovered the influence of impurities on the surface tension of fluids doing the dishes in her own kitchen.
  • Despite her lack of formal training, Pockels was able to measure the surface tension of water by devising the slide trough, a key instrument in the new discipline of surface science.
  • She first published her work in Nature in 1891.

Maud Menten was among the first women in Canada to earn a medical doctorate.

​

In 1912, she published a paper that showed that the rate of an enzyme-catalyzed reaction is proportional to the amount of the enzyme-substrate complex.

​

This relationship between reaction rate and enzyme–substrate concentration is known as the Michaelis–Menten equation.

The first Mexican-born scientist to win a Nobel Prize in Chemistry, Mario Molina discovered the serious environmental threat posed by chlorofluorocarbon gases (CFCs).

​

Along with fellow chemist Sherwood Rowland, Molina found that CFCs—chemicals commonly used as refrigerants, and colloquially known as Freon—released into the atmosphere were contributing to ozone depletion.

Dr. Charles Richard Drew broke barriers in a racially divided America to become one of the most important scientists of the 20th century.

​

His pioneering research and systematic developments in the use and preservation of blood plasma during World War II.

​

Drew aspired to continue training in transfusion therapy at the Mayo Clinic, but racial prejudices at major American medical centers barred black scholars from their practices.

Mildren Cohn overcame gender and religious prejudice to leave a profound impact on biochemistry and biophysics.

​

Among the first scientists to apply electron spin and NMR to investigate metabolism.

​

She pioneered the use of NMR to determine how enzymes and other proteins behave during chemical reactions in the body.

​

Her are now widely practiced by other scientists to study metabolic processes at the molecular level.

The young Yellapragada SubbaRow flunked out of two high schools in India until the death of his father caused him to buckle down to his studies.

​

He co-discovered phosphocreatine and ATP with Cyrus Fiske besides devising the colorimetric method for phosphorus estimation known as the Fiske-SubbaRow Method.

​

In 1940, he directed the research that led to the synthesis of folic acid, discovery of tetracycline, methotrexate, and diethylcarbamazine.

David Liu is leading the charge in conceiving improved versions of CRISPR, the gene-editing tool that is revolutionizing research.

​

His most notable advance is a new “base editor” that can swap a single nucleotide base, or letter, of DNA for another.

​

The invention opens the door to developing treatments for the thousands of genetic diseases caused by one small typo in DNA.

Patsy Sherman was a 1952 alumnus of Gustavus Adolphus College

​

She was the co-inventor along with Samuel Smith of Scotchgard while an employee of the 3M corporation in 1952. An accidental spill of a fluorochemical rubber on an assistant’s tennis shoe was the beginning to the invention of the product.

​

Sherman holds 13 patents with Smith in fluorochemical polymers and polymerization processes.

Edith Ellen Humphrey was a British inorganic chemist who carried out pioneering work in co-ordination chemistry at the University of Zurich under Alfred Werner.

​

She is thought to be the first British woman to obtain a doctorate in chemistry.

​

Humphrey was "the first of his students to succeed in preparing Werner's first new series of geometrically isomeric cobalt complexes, a class of compounds that were crucial in his development and proof of his coordination theory.

The Cori Cycle — the process of sugar metabolism — is named after husband-and-wife team Gerty Theresa Cori and Carl Ferdinand Cori (1896-1984).

​

They are responsible for helping us understand how cells use food and convert it to energy through a cyclical process in the muscles.

​

Their landmark carbohydrate research not only led to the development of treatments for diabetes, it also made them winners of the 1947 Nobel Prize in physiology or medicine.

Barbara S. Askins is best known for her invention of a method to enhance underexposed photographic negatives.

Askins' method prompted improvements in the development of X-ray images.

This development was used extensively by NASA and the medical industry, and it earned Askins the title of National Inventor of the Year in 1978.
