1905

Nobel Prize in Physics

Philipp Lenard

Lenard received the prize for his work on cathode rays — streams of electrons he could deflect, measure, and study in detail — work that genuinely advanced understanding of atomic structure. He later became an ardent Nazi and spent his final years attacking Einstein's "Jewish physics." The prize, which predated all of this, cannot be held responsible.

Nobel Prize in Chemistry

Adolf von Baeyer

Baeyer had synthesized indigo in 1880, breaking the monopoly of natural plant dye that had coloured clothing for millennia. His work on organic dyes and the ring structures of hydroaromatic compounds gave the chemical industry both the science and the tools to manufacture colour at scale. He was 72 when the prize arrived.

Nobel Prize in Physiology or Medicine

Robert Koch

Koch isolated the bacterium Mycobacterium tuberculosis in 1882, demonstrating for the first time that a specific microbe caused a specific disease — establishing what are still called Koch's postulates. Tuberculosis killed one in seven people in 19th-century Europe. His prize recognised not just the discovery but the framework that made it possible to think clearly about infectious disease at all.

Nobel Prize in Literature

Henryk Sienkiewicz

Sienkiewicz's historical novel Quo Vadis, set in Nero's Rome, had become an international bestseller translated into dozens of languages — the kind of popular success that literary committees sometimes find suspicious and sometimes reward. They rewarded it. He had also written a trilogy of historical novels about Poland at a time when Poland did not exist as a nation, which carries its own weight.

Nobel Peace Prize

Bertha von Suttner

Von Suttner's 1889 novel Lay Down Your Arms — a vivid account of war's suffering told through a woman's eyes — had become an unexpected bestseller and shaken loose a generation of pacifist sentiment across Europe. She had lobbied Alfred Nobel personally, and some believe she helped persuade him to include a Peace Prize in his will. She was the first woman to win it.

Einstein publishes special theory of relativity

The paper Einstein submitted in June 1905, "On the Electrodynamics of Moving Bodies," contained no footnotes and cited almost no prior literature — because it needed neither. It established that the speed of light is constant for all observers, that time and space are not fixed backdrops but flexible quantities, and that the laws of physics look the same no matter how fast you are moving. It was written in a spare, almost conversational style for a paper that dissolved the foundations of Newtonian mechanics.

Einstein explains the photoelectric effect

Shine light on a metal surface and electrons fly off — but only if the light exceeds a certain frequency, regardless of its brightness. Einstein explained this by proposing that light comes in discrete packets of energy (photons), each carrying a fixed amount depending on frequency. This was the paper that ultimately won him the 1921 Nobel Prize, which gives you some sense of how long Nobel committees take to think things over.

Einstein's paper on Brownian motion

Pollen grains and dust particles suspended in water jitter constantly and randomly — observed by botanist Robert Brown in 1827, unexplained for eighty years. Einstein derived the mathematics of this jitter from first principles, treating the liquid as composed of discrete molecules that were bumping into the particle. The paper was, among other things, proof that atoms existed, at a time when this was not considered obvious.

Einstein derives E=mc²

A short follow-up paper in September asked whether the energy content of a body depends on its inertia — and answered yes, in three pages, with the relation E=mc². The speed of light squared is an enormous number. Even a small mass, it followed, contains energy on a scale that would take decades to reckon with fully.
