Theodore William Richards and the Weight of Chemical Elements

Theodore William Richards and the Weight of Chemical Elements

On January 31, 1868, American chemist Theodore William Richards was born. Richards was the first American scientist to receive the Nobel Prize in Chemistry “in recognition of his accurate determinations of the atomic weight of a large number of chemical elements.” His work meticulously refined the classical gravimetric methods of analysis to better reduce the sources of error. Together with his co-workers, he was able to measure accurate values for…
Sir William Jenner and the Distinction of Typhus and Typhoid

Sir William Jenner and the Distinction of Typhus and Typhoid

On January 30, 1815, English physician Sir William Jenner was born. Jenner is primarily known for having discovered the distinction between typhus and typhoid. While “typhoid” means “typhus-like”, typhus and typhoid fever are distinct diseases caused by different genera of bacteria. William Jenner attended University College, London where he studied medicine. Jenner was further apprenticed to a surgeon in Marylebone. William Jenner was appointed surgeron to the Royal Maternity Charity,…

Abdus Salam’s Electroweak Unifying Theory

On January 29, 1926, Pakistani theoretical physicist Mohammad Abdus Salam was born. Abdus Salam shared the 1979 Nobel Prize in Physics with Sheldon Glashow and Steven Weinberg for his contribution to the electroweak unification theory. Mohammad Abdus Salam was born in Jhang, a small town in what is now Pakistan, into a Muslim Punjabi family.

Victor Moritz Goldschmidt and the Origins of Geochemistry

On January 27, 1888, Swiss-Norwegian geochemist, mineralogist and petrologist Victor Moritz Goldschmidt was born. Goldschmidt is considered (together with Vladimir Vernadsky) to be the founder of modern geochemistry and crystal chemistry, as well as the developer of the Goldschmidt Classification of elements. Goldschmidt was born in Zürich, Switzerland, into a family of Jewish parents, Heinrich Jacob Goldschmidt, a distinguished physical chemist, who held professorships at Amsterdam, Heidelberg, and Oslo, and…
Ancel Keys and the Saturated Fats

Ancel Keys and the Saturated Fats

On January 26, 1904, American nutritionist and epidemiologist Ancel Keys was born. Keys studied the influence of diet on health. In particular, he hypothesized that saturated fat in the diet is unhealthy and should be avoided. He also was the first to identify the role of saturated fats in causing heart disease. Ancel Keys began to study chemistry at Berkeley but took time off to work as an oiler aboard the…

Theodosius Dobzhansky and the Unifying modern Evolutionary Synthesis

On January 25, 1900, American geneticist and evolutionary biologist Theodosius Dobzhansky was born. Dobzhansky was a central figure in the field of evolutionary biology for his work in shaping the unifying modern evolutionary synthesis. He made the first significant synthesis of Charles Darwin‘s theory of evolution with Gregor Mendel‘s theory of genetics in his book Genetics and the Origin of Species (1937). “[Evolution] is a general postulate to which all…

Ernst Heinkel and His Aircraft

On January 24, 1888, German aircraft designer an manufacturer Ernst Heinkel was born. Heinkel’s company Heinkel Flugzeugwerke produced the Heinkel He 178, the world’s first turbojet aircraft and jet plane, and the Heinkel He 176, the first rocket aircraft. Ernst Heinkel was apprenticed as machinist at a foundry and later studied at the Technical Academy of Stuttgart. There Heinkel became enthusiastic for aviation and fascinated by Zeppelins. Around 1910, Heinkel built his first aircraft…
Hideki Yukawa and the Existence of Mesons

Hideki Yukawa and the Existence of Mesons

On January 23, 1907, Japanese theoretical physicist and the first Japanese Nobel laureate Hideki Yukawa was born. Yukawa shared the 1949 Nobel Prize for Physics for “his prediction of the existence of mesons on the basis of theoretical work on nuclear forces.” “Reality is cruel. All of the naivete is going to be removed. Reality is always changing, and it is always unpredictable. All of the balance is going to…
Albert Neisser and the Causative Agent of Gonorrhea

Albert Neisser and the Causative Agent of Gonorrhea

On January 22, 1855, German physician Albert Ludwig Sigesmund Neisser was born. Neisser discovered the causative agent (pathogen) of gonorrhea, a strain of bacteria that was named in his honour (Neisseria gonorrhoeae). Albert Neisser was the son of the back then well known physician Dr. Moritz Neisser. He studied at St. Maria Magdalena School in Breslau where he was a contemporary of the German physician and scientist Paul Ehrlich. Neisser obtained…
