1974

Nobel Prize in Physics

Martin Ryle · Antony Hewish

Ryle's aperture synthesis technique stitches together signals from multiple radio telescopes to mimic a single instrument far larger than any one dish — like convincing ten musicians playing the same note to sound like one enormous pipe organ. Hewish's team discovered pulsars using the resulting radio maps, though it was graduate student Jocelyn Bell Burnell who first noticed the clockwork flashes in the data.

Nobel Prize in Chemistry

Paul J. Flory

Polymers — plastics, rubber, proteins, DNA — are long chains whose physical behaviour puzzled chemists for decades. Flory built the statistical and thermodynamic framework for understanding how they coil, stretch, and interact with solvents, work so foundational that it underpins both materials science and molecular biology without always being credited for either.

Nobel Prize in Physiology or Medicine

Albert Claude · Christian de Duve · George E. Palade

Claude worked out how to spin cells apart in a centrifuge and examine the pieces; de Duve discovered that one of those pieces — the lysosome — was the cell's recycling department, full of digestive enzymes; Palade traced the path a protein takes from ribosome to endoplasmic reticulum to Golgi apparatus to the cell surface. Together they gave us the first detailed map of the cell as a working factory.

Nobel Prize in Literature

Eyvind Johnson · Harry Martinson

Two Swedish novelists sharing the prize was unusual; that both were sitting members of the Swedish Academy that chooses the prize was, let us say, a situation requiring tact. Johnson wrote sweeping historical fiction; Martinson, once a merchant seaman and farmhand, wrote Aniara — an epic poem set on a spacecraft drifting irretrievably away from a ruined Earth.

Nobel Peace Prize

Seán MacBride · Eisaku Satō

MacBride co-founded Amnesty International and spent his career documenting what governments do to people when no one is watching; Satō was Japan's longest-serving postwar prime minister and steered his country toward signing the Nuclear Non-Proliferation Treaty. Pairing a human rights lawyer with a conservative statesman was the Peace Prize at its most diplomatically ambitious.

Sveriges Riksbank Prize in Economic Sciences

Gunnar Myrdal · Friedrich von Hayek

Myrdal believed market failures and social structures required active intervention; Hayek believed that dispersed price signals carry information no central planner could replicate. Giving them the same prize in the same year was either a masterstroke of balance or an admission that economics had not yet settled some rather important questions.

ACM A.M. Turing Award

Turing Award

Donald E. Knuth

Knuth's multi-volume The Art of Computer Programming set out to be a survey of existing algorithms and became, in the writing, a rigorous mathematical discipline. He also built TeX to typeset the volumes to his satisfaction, because no existing software could, which was characteristic.

Fields Medal

Fields Medal

Enrico Bombieri · David Mumford

At the 1974 International Congress in Vancouver, Bombieri was recognised for his large-sieve methods in analytic number theory and contributions to minimal surfaces; Mumford for his work on algebraic geometry and the theory of moduli spaces, the mathematical objects that classify algebraic curves and surfaces by shape.

Discovery of 'Lucy' (Australopithecus afarensis)

On 24 November 1974, Donald Johanson and Tom Gray found 40 percent of a hominin skeleton eroding out of a hillside at Hadar in northeastern Ethiopia. Dated to 3.2 million years ago, the specimen — named Lucy after the Beatles song playing in camp that evening — had a brain the size of a chimpanzee's but knee joints unmistakably designed for walking upright, separating locomotion and intelligence in human evolution by millions of years.
