Alfred Nobel 

Date of Birth: October 21, 1833

Notable Works: 

  • Invention of Dynamite (1866): Nobel developed dynamite by stabilizing nitroglycerin with kieselguhr, a fine sand. This invention revolutionized construction, mining, and engineering by providing a safer and more effective explosive.
  • Detonator (Blasting Cap): He invented a reliable detonator, which made the controlled use of explosives possible, ensuring precision and safety in applications.
  • Industrial Expansion: Nobel established factories in over 20 countries, creating a global industrial network to produce dynamite and other innovations. He held 355 patents by the time of his death.
  • Synthetic Materials: Beyond explosives, Nobel experimented with synthetic rubber, artificial silk, and leather, showcasing his broad interest in industrial chemistry.
  • The Nobel Prizes: Nobel’s most enduring legacy is the establishment of the Nobel Prizes. His will allocated much of his fortune to reward outstanding achievements in Physics, Chemistry, Medicine, Literature, and Peace, promoting advancements that benefit humanity.

Charles Glenn King

Date of Birth: October 22, 1896

Notable Works: 

Ascorbic acid
  • Isolation of Vitamin C (1931-1932): King successfully isolated vitamin C while studying the antiscorbutic (anti-scurvy) properties of lemon juice using guinea pigs. This work paralleled Albert Szent-Györgyi’s research on hexuronic acid, later identified as vitamin C. King and Szent-Györgyi published their findings within weeks of each other.
  • Pioneering Nutritional Science: King significantly contributed to understanding the roles of vitamins in human health, particularly vitamin B. His work helped establish the importance of a balanced diet for preventing nutritional deficiencies.
  • Development of Nutritional Standards: King contributed to creating the Recommended Dietary Allowances (RDA), ensuring adequate nutrient intake guidelines for public health.
Antonie van Leeuwenhoek

Antonie van Leeuwenhoek

Date of Birth:  October 24, 1632 

Notable Works: 

Discovery of Microorganisms:

  • Van Leeuwenhoek was the first to observe and describe microscopic organisms (which he called “animalcules”), including bacteria, protozoa, and spermatozoa.
  • He examined samples from various sources like pond water, teeth scrapings, and his own blood.

Advanced Microscopy:

  • He created over 500 optical lenses and at least 25 microscopes, some capable of magnifications up to 500x.
  • His lenses allowed unprecedented observation of tiny life forms, enabling the establishment of microbiology as a scientific discipline.

Pioneering Techniques:

  • Van Leeuwenhoek used his microscopes to describe red blood cells, muscle fibers, and the vacuole in plant cells.
  • He was among the first to document the flow of blood in capillaries and used histological stains in his studies.

Robert Stirling

Date of Birth: October 25, 1790

Notable Works: 

Rev Stirling's concept air engine, 1827, Hunterian Museum, Glasgow
  • Stirling Engine (1816):
    • Stirling invented the heat engine known as the Stirling engine, which operates on a closed-cycle regenerative heat process.
  • Economiser (Regenerator):
    • The Economiser was a key part of the Stirling engine and acted as a regenerative heat exchanger, significantly improving the efficiency of heat engines.
  • Advancements in Heat Engine Design:
    • The engines operated effectively at foundries in Dundee for several years, demonstrating their utility in industrial applications.
    • In 1840, Stirling made significant improvements to his engine, incorporating better cooling systems and materials to increase durability.

  • A foot pedal (treadle) for hands-free operation.
  • An oscillating shuttle for smoother stitching.
  • A table for fabric support and better usability.

His patented designs in 1854 revolutionized sewing by addressing the shortcomings of earlier models.

  • In 1955, Salk introduced the inactivated polio vaccine (IPV), marking a major milestone in the fight against polio.
  • Salk’s decision not to patent the vaccine ensured its widespread accessibility, reflecting his commitment to global health.
  • By 1959, the vaccine had reached over 90 countries, significantly reducing polio cases worldwide.

Adolf von Baeyer

Date of Birth: October 31, 1835

Notable Works: 

Indigo dye
  • Baeyer successfully synthesized indigo, a natural dye previously derived from plants. His method revolutionized the production of indigo, making it more accessible and affordable.
  • He discovered phenolphthalein, a compound widely used as a pH indicator in laboratories.
  • Baeyer synthesized fluorescein, one of the first synthetic fluorophores, used in applications ranging from microscopy to ophthalmology.
  • His discovery of barbituric acid in 1864 laid the foundation for the development of barbiturates, an important class of sedative-hypnotic drugs.
