Here are 16 scientists whose achievements made them famous and whose tragically short lives have left us wondering how much more they might have achieved had they been given more time.

Writing this piece made me appreciate the relatively healthier times we live in now. Of the 16 deaths below, 7 were linked to tuberculosis.

Like some other infections these days, tuberculosis is becoming more resistant to medication. Let’s hope medical research can stay ahead of it.

## Evariste Galois

**1811 – 1832**

At the age of 20, probably as a result of a romantic affair gone wrong, Evariste Galois fought a duel in Paris. He was shot, dying the following day.

In the days before the duel, convinced that he would be killed, he poured out his mathematical thoughts on pieces of paper and sent them to his friend, Auguste Chevalier. The papers described an entirely new, immensely important field of mathematics – group theory.

## Niels Henrik Abel

**1802 – 1829**

Niels Abel discovered group theory independently of Evariste Galois. (Group theory seems to have brought uncommonly bad luck to its discoverers!) In addition group theory, Abel discovered elliptic functions and was the first person to prove the binomial theorem for all numbers.

## Henry Moseley

**1887 – 1915**

In 1913, Henry Moseley discovered that every chemical element’s identity is determined by its number of protons. In doing so, he discovered the true basis of the periodic table.

## Gotthold Eisenstein

**1823 – 1852**

The third of our unfortunate trio of mathematicians who died before their 30th birthdays is Gotthold Eisenstein, of whom the great mathematician Carl Friedrich Gauss wrote:

[his mathematical] talent is of the type that nature bestows only a few times a century.

Eisenstein proved theorems in number theory and analysis that Gauss himself had been stymied by.

## Srinivasa Ramanujan

**Lived 1887 – 1920**

Srinivasa Ramanujan was a largely self-taught pure mathematician. Hindered by poverty and ill-health, his highly original work considerably enriched number theory and, more recently, physics.

## Johann Wilhelm Ritter

**1776 – 1810**

Johann Ritter discovered ultraviolet radiation in 1801. He detected it using a chemical reaction and called the radiation ‘oxidizing rays.’

## William Kingdon Clifford

**1845–1879**

William Clifford was a mathematician with ideas rather ahead of his time. He proposed that matter results from curvature in space and that gravity is a natural consequence of this curvature – one of the key concepts in Albert Einstein‘s general theory of relativity.

Clifford founded Clifford algebra, including geometric algebra.

## Curt Schimmelbusch

**1860 – 1895**

*Guide to the Aseptic Treatment of Wounds*describing techniques to minimize the risks of infection during medical treatment.

He also invented a sterilizer to allow surgeons’ tools to be steam cleaned before use, then carried in their own sealed box to the operating theater.

The Schimmelbusch mask, which allowed ether and chloroform anesthetics to be given to patients as vapors, was used in Germany for over six decades.

## Heinrich Hertz

**1857 – 1894**

In a series of brilliant experiments Heinrich Hertz discovered radio waves and established that James Clerk Maxwell’s theory of electromagnetism is correct. Hertz also discovered the photoelectric effect, providing one of the first clues to the existence of the quantum world. The unit of frequency, the hertz, is named in his honor.

## Ada Lovelace

**1815 – 1852**

Ada Lovelace was a pioneer of computing science. She took part in writing the first published program and was a computing visionary, recognizing for the first time that computers could output more than just calculations.

## Nicolas Léonard Sadi Carnot

**1796 – 1832**

Nicolas Carnot introduced the concepts of the heat engine and the thermodynamic system. He proved that the efficiency of a perfect engine is determined solely by the temperatures of a hotter reservoir and a colder reservoir. His work remained largely unknown until two years after his death, when Émile Clapeyron updated it, inspiring Lord Kelvin and Rudolf Clausius to make tremendous advances in the new science of thermodynamics, introducing the second law of thermodynamics and entropy.

## Rosalind Franklin

**1920 – 1958**

Rosalind Franklin carried out X-ray diffraction research into the structure of DNA. Her X-ray photography was a critical factor in the discovery of its iconic double-helix structure. Franklin also carried out ground-breaking work revealing the molecular structures of viruses.

## Bernhard Riemann

**1826 – 1866**

Bernhard Riemann was a mathematician who made a difference. He produced the first rigorous formulation of the integral; discovered Riemann surfaces; and put forward the Riemann hypothesis.

When Fermat’s last theorem was proved by Andrew Wiles in 1995, the Riemann hypothesis became probably the most famous long-lasting unsolved problem in mathematics. A prize of $1 million has been offered by the Clay Mathematics Institute to anyone who can prove the Riemann hypothesis.

Riemann considered the properties of n-dimensional space, defining a Riemannian space, and the curvature tensor. This work was visionary and decades were to pass before Albert Einstein utilized it in his general theory of relativity.

## Augustin Fresnel

**1788 – 1827**

Augustin Fresnel was a physicist whose major works dealt with the properties of light. He invented the Fresnel lens for use in lighthouses, allowing the light to be seen from farther away. Since then the Fresnel lens has found many more uses including hand-held magnifiers, traffic lights, and correcting eyesight disorders.

## Blaise Pascal

**1623 – 1662**

Blaise Pascal was a polymath who made important contributions in mathematics and physics. Among other achievements, he invented the mechanical calculator; he devised Pascal’s triangle, producing the binomial coefficients in a highly accessible way; he invented the hydraulic press; and he cooperated with Pierre de Fermat in the invention of the new mathematics of probability.

## Walter Sutton

**1877 – 1916**

Walter Sutton was a physician and geneticist. He advanced the idea that Gregor Mendel’s laws of inheritance could be applied to chromosomes. Sutton-Boveri theory correctly linked the paired factors required by Mendel’s laws with chromosomes.

## Extreme Mathematicians

If you’ve started to think mathematicians have a habit of dying young, it’s worth pointing out that 4 out of 5 of the longest lived scientists were also mathematicians.

Thanks for drawing attention to the devastation TB caused at one time in the West. The disease is still a major problem elsewhere. Last year about 5,000 people in the World died every day of TB and there are almost 30,000 new cases every day. The real worry is an epidemic of a new TB strain that’s totally resistant to all drugs and there are TB strains evolving in that direction. The World Health Organization believes $400 million more needs to be spent on TB research every year to fight it effectively. That’s about what it cost to make Pirates of the Caribbean. What good is a movie if there’s an epidemic of incurable TB?
