Here are profiles of 25 great scientists who lived for over 100 years, with the oldest reaching 110 years of age. Of the five who reached the greatest ages four were mathematicians. The highest age at which anyone published new work was 103 and the highest retirement age from teaching was 104.
Dorrit Hoffleit lived for 100 years, from March 12 1907 to April 9 2007. She was born in Florence, Alabama, USA and died in New Haven, Connecticut, USA.
She co-discovered the optical variability of the quasar 3C 273, the first quasar ever identified, and co-authored The General Catalogue of Trigonometric Stellar Parallaxes, offering precise distances to over 8000 stars, information that is essential to understanding the dynamics and evolution of our Milky Way galaxy.

He specialized in the study of human nutrition and is remembered for formulating K-rations for American soldiers in World War 2 and hypothesizing and promoting the health benefits of the Mediterranean Diet.
Claude Lévi-Strauss lived for 100 years, from November 28 1908 to October 30 2009. He was born in Brussels, Belgium and died in Paris, France.
Held to be one of the fathers of modern anthropology, he was responsible for the field of structural anthropology – the idea that all forms of human activity are founded on the same basic thought patterns.
Raymond Firth lived for 100 years, from March 25 1901 to February 22 2002. He was born in Auckland, New Zealand and died in London, England, UK.
He was a professor of anthropology, responsible for the splitting of social organization from social structure. He was still writing in his hundredth year. He seems to have inherited genes for long life from his father, who lived to the age of 104.
Frances Kelsey lived for 101 years, from July 24 1914 to August 7 2015. She was born on Vancouver Island, British Columbia, Canada and died in London, Ontario, Canada.
She was a pharmacologist and medical doctor, who saved thousands of children from birth defects by blocking American sales of the drug thalidomide, stating that its manufacturers had not fully assessed the drug’s risks.
Friedrich Hund lived for 101 years, from February 4 1896 to March 31 1997. He was born in Karlsruhe, Germany and died in the same city.
He was a physicist, famous for molecular orbital theory and Hund’s Rule, which determines how the electron shells in an atom are filled. Robert Mulliken, winner of the 1966 Nobel Prize in Chemistry said Hund’s work had been of great importance to his own research and that, in a fairer world, they would have been awarded the prize jointly.
Charles Abbot lived for 101 years, from May 31 1872 to December 17 1973. He was born in Wilton, New Hampshire, USA and died in Riverdale, Maryland, USA.
He specialized in studying the sun’s electromagnetic radiation, charting variations in the sun’s energy output and relating these variations to climate patterns experienced on Earth. He invented and patented a number of solar energy devices, including the solar boiler, solar cooker and solar still.
Harriette Chick lived for 102 years, from January 6 1875 to July 9 1977. She was born in London, England, UK and died in the same city.
She was a biochemist. Working with colleagues, she initiated the new field of protein folding with the discovery that protein denaturation was not the same as protein coagulation. She and Elsie Dalyell led research into rickets, discovering that the disease was not transmissible, but was caused by a nutritional deficiency, which could be cured with cod-liver oil or ultra-violet light. (We now know rickets is caused by vitamin D3 deficiency.) Chick also devised Chick’s Law, which later became the Chick-Watson equation.
Michel Chevreul lived for 102 years, from August 31 1786 to April 9 1889. He was born in Angers, France and died in Paris, France.
He was a professor of chemistry who discovered margaric acid and creatine. Funnily enough, he was also a specialist in the science of aging!
Albert Hofmann lived for 102 years, from January 11 1906 to April 29 2008. He was born in Baden, Switzerland and died in Burg im Leimental, Switzerland.
While working as a chemist for Sandoz, a Swiss pharmaceutical company, he discovered lysergic acid diethylamide, better known as the psychedelic drug LSD. Hofmann discovered the drug’s mind-altering effects when he accidentally ingested a tiny grain of it. The drug was used in psychoanalysis therapy for 10 years before it was banned.
George Rosenkranz lived for 102 years, from August 20 1916 to June 23 2019. He was born in Budapest, Hungary and died in Atherton, California, USA.

A mathematician, he contributed new ideas in gamma functions, complex functions, elliptic functions, non-Euclidean geometry, and the roots of transcendental functions. He continued publishing new research until he was 98 years old, and retired when he reached 100.
Michael Heidelberger lived for 103 years, from April 29 1888 to June 25 1991. He was born in New York City, USA and died in the same city.
He was the founder of the science of immunochemistry. Working with Oswald Avery, he discovered that the antigens of pneumococcus bacteria are polysaccharides, and therefore that antibodies are proteins.
Rita Levi-Montalcini lived for 103 years, from April 22 1909 to December 30 2012. She was born in Turin, Italy and died in Rome, Italy.
After graduating as a Doctor of Medicine, she opted for a career in medical research. She won the 1986 Nobel Prize in Physiology or Medicine for the discovery of nerve growth factor (NGF).

He was an engineer-inventor whose wide interests included space research and computer engineering. He invented improved induction welding methods, which were used in aircraft production during WW2. He also invented a radar-jamming device, which was highly effective, and saved countless pilots’ lives. Regarding the mystery of his long life, he said you need to “select the right grandparents, have a good family life, and don’t let the armchair get you.”
Arnold Beckman lived for 104 years, from April 10 1900 to May 18 2004. He was born in Cullom, Illinois, USA and died in La Jolla, California, USA.
He invented one of the most important tools in chemistry and biology – the pH meter. He started up Beckman Instruments, then developed the DU spectrophotometer, going on to fund the first transistor company in California – the beginnings of Silicon Valley.
Henri Cartan lived for 104 years, from July 8 1904 to August 13 2008. He was born in Nancy, France and died in Paris, France.
A mathematician specializing in algebraic topology, he developed the Cartan Model. He was a founder of the influential Bourbaki Group, whose objective was to reconfigure mathematics to be based on set theory.

Dr. Ray Crist was Emeritus professor when I was in college. By then his research focused on algae/metals and pollution. We all knew he had worked on the Manhatten Project, and that he didn’t like to discuss it. But I never knew the significance of the role he played until I read his memoir recently. He wrote it just before he died. He worked directly with Harold Urey and other famous scientists. He once visited Einstein at his home in Princeton, NJ. To think I had the opportunity to work with him on a seminar project but chose a different project instead is something I’ll forever regret, although, I just didn’t know or realize he was one of the best scientists to ever live.
You could add another great scientist to this list: David Shugar ,
Canadian- Polish born scientist living in Warsaw celebrated his 100th anniversary in September 2015 .
He oriented the research of many a scientist into the field of nucleosides and nucleotides .
Dr. A.D.Padhye says
Wish all Nobel laureates and other greatest of the scientists also live such a long life to make the human kind a favor.
This is amazing!
Also amazing is that people born in 2015 have about a 1 in 3 chance of making it to 100!
