Chemistry

• Nikolai Menshutkin discovers that a tertiary amine can be converted into a quaternary ammonium salt by reaction with an alkyl halide – the Menshutkin reaction.
• Emil Fischer establishes the stereochemistry and isomeric nature of the sugars by epimerization between gluconic and mannonic acids and synthesizes glucose, fructose and mannose from glycerol.

Computer science

• June 1 – The United States Census Bureau begins using Herman Hollerith's tabulating machine to record census returns using punched card input, a landmark in the history of computing hardware. Hollerith's company eventually becomes IBM.

Earth sciences

• The phosphate mineral messelite (from Messel in Germany) is first described.

Mathematics

• Philippa Fawcett is placed above the Senior Wrangler in the Mathematical Tripos at the University of Cambridge in England.
• P. J. Heawood proves the five colour theorem.
• Giuseppe Peano is the first to demonstrate a space-filling curve.

Medicine

• Discovery by Emil von Behring and Kitasato Shibasaburō that an anti-toxin for immunizing people against diphtheria can be prepared by injecting diphtheria toxin into animals.
• Curt Schimmelbusch invents the Schimmelbusch mask for the safe delivery of anesthetics to surgical patients.
• Santiago Ramón y Cajal publishes the first edition of Manual de Anatomia Pathologica General.
• Robert Koch publishes his postulates on the causal relationship between microbes and diseases.
• William James publishes The Principles of Psychology.

Technology

• May – Herbert Akroyd Stuart, in collaboration with Charles Richard Binney and Richard Hornsby & Sons, files a British patent for Improvements in Engines Operated by the Explosion of Mixtures of Combustible Vapour or Gas and Air, the first successful design of hot bulb engine, which will be produced as the heavy-oil Hornsby-Akroyd oil engine.
• August 6 – At Auburn Prison in New York, William Kemmler becomes the first person to be executed in the AC electric chair.
• October 9 – The first brief flight of Clément Ader's steam-powered fixed-wing aircraft Eole takes place in Satory, France. It flies uncontrolled approximately 50 m at a height of 20 cm, the first take-off of a powered airplane solely under its own power.
• Approximate date – British civil engineer Ernest William Moir invents the airlock while working in New York.
• Scottish American chemist William Morrison produces the first successful practical electric road vehicle in the United States.
• The precut paperboard box is invented by Robert Gair, a Brooklyn printer and packaging producer.
• The Hurter and Driffield film speed measurement system is described.
