Excellent scientists that you probably haven’t heard of

There are some scientists that everyone has heard of; Darwin, Newton and Curie all spring to mind. Of course, their scientific discoveries were all legendary. But what about the people who have contributed just as much to the world of science but who maybe aren’t so famous? Here I’ve compiled a small list of some of the scientists I think have contributed just as much to our understanding of the modern world as those mentioned above. Although many of these people have been recognised in their fields and some have even won Nobel Prizes, their names have never entered the wider public consciousness.

1.       Rosalind Franklin (1920 – 1958) and Maurice Wilkins (1916  – 2004)

Whilst Franklin and Wilkins are probably the best-known names on this list, they are not as well-known as they should be.  The discovery that DNA is a double helix is now forever associated with (James) Watson and (Francis) Crick. However, there were other names involved in this remarkable achievement, including Wilkins and Franklin who were working at King’s College London at the time of the discovery. Maurice Wilkins even shared the 1962 Nobel Prize with Watson and Crick, yet somehow his name has been lost from the public consciousness. His student was Rosalind Franklin, whose work with X-Ray diffraction was the key to confirming that DNA is indeed a double helix. Much has been made of Franklin not winning the Nobel Prize along with Watson, Crick and Wilkins. But, the sad fact is that the Nobel Prize is not awarded posthumously and by the time the discovery received this honourable recognition she had sadly passed away – at the tragically young age of 37. However, what I believe to be even more scandalous, is that her contribution seems to have been entirely overlooked until a few years ago when the deserved recognition began to flow in.

As for Wilkins, Watson himself states in his autobiography ‘The Double Helix’: “I proceeded to forget about Maurice, but not his DNA photograph”1. There is no doubt that the work done by Wilkins and Franklin was instrumental in aiding Crick and Watson with their ground-breaking discovery and their names certainly deserve to be remembered!

2.       George Gey (1899 – 1970)

Although he is a figure of some controversy, I think George Gey (pronounced “guy”) deserves to be on this list. Gey was the first person to propagate the HeLa cell line – the first human cells to be successfully grown in a laboratory environment. Since then, scientists have used HeLa cells, and other cell lines created since, to make many important breakthroughs, including the discovery of a treatment for polio. And they are still used in thousands of labs across the world, including mine (see picture).

The controversy surrounding Gey2 is the fact that the HeLa cells were taken from a cervical cancer patient, Henrietta Lacks, without her permission. Gey did not ask Henrietta or her family for permission to use or distribute the cells. The cell line was later patented and has made those who patented it (incidentally, not Gey or his family) very rich. Henrietta’s family received no money for the use of her cells, and until recently, Henrietta’s contribution went unacknowledged. George Gey however, did not have such financial motives; once he managed to successfully grow the HeLa cells, he gave them away to fellow scientists.

Whilst controversy remains as to how much money the Lacks family should be entitled to, I like to remember George Gey; the man who started it all out of altruism with no financial motives, a quality that should be admired.

3.       Sir Edwin Southern (1938 – )

Here’s one for fellow biochemists. Edwin Southern is a British molecular biologist and inventor of the Southern blot. This is a method for detection of DNA, now commonly used in DNA fingerprinting and genetic profiling. The Southern blot was later developed into the cleverly-named Northern Blot – modified to detect the other form of genetic material, RNA. Even better, the development of the Southern Blot finally led to development of the Western Blot – a method used to detect proteins. These methods are probably used by every biochemistry lab across the world, including mine (see picture).

The Southern blot and its offshoots have become staple practices in the lab and have made way for many important discoveries. Yet I know few biochemists who have even heard of Edwin Southern or his contributions to the scientific methods they use on a daily basis.

4.       Dorothy Crowfoot Hodgkin (1910 – 1994)

Another British scientist, Dorothy Hodgkin, won the Nobel Prize in Chemistry in 1964 for discovering the structure of vitamin B12. She was a pioneer in the field of X-Ray crystallography, working on solving the crystal structure of proteins. Her knowledge was instrumental in the discovery of the structure of several proteins, but arguably her greatest achievement was in leading the team that solved the structure of insulin. This discovery led to the development of synthetic insulin – now widely used to treat people with type I diabetes.

Hodgkin has been recognised for her work in the scientific community. Along with the Nobel Prize she was also the first woman to win the prestigious Copley Medal. Some of her fellow recipients include Charles Darwin and Stephen Hawking. She was a true pioneer, not just for women in science but also for promoting peace and aid for developing countries. (According to her Wikipedia page, she did teach Margaret Thatcher, but I guess nobody’s perfect.)

While you could argue that most of these names are well-known in scientific circles, they have not become household names along with the likes of Darwin and Hawking. And this is by no measure an exhaustive list!

Perhaps one of the most endearing qualities of great scientists is that they rarely do what they do for fame or fortune. In fact, many actively shy away from the limelight. People like George Gey and Dorothy Hodgkin were certainly more interested in curing disease and adding to our understanding of the world than earning money or becoming famous. So this is just my way of thanking them for their tireless work and recognising the contributions they have made to modern science.

  1. Great conversation starter – back to school this week and my students are hunting for “obscure” scientists who changed the world with bonus points if no one else chooses that person. Hoping to have a wall of scientific discovery to start the year.

  2. Prescription Creams – If you call at your doctor, he’ll almost certainly often prescribed a cream or lotion for your psoriasis condition. Only use good complete clean salt; that cheap salt can be for sidewalks, to keep
    us from slipping, or a lot of people use it
    on the stove to help keep food that overflows beyond
    pans from sticking, but it mustn’t be considered real food because it has become
    altered. Nature gives an abundance of foods this time around of
    the season to keep us cool and nourished.

  3. I simply desired to say thanks yet again. I am not sure the things that I would have carried out without the type of recommendations shared by you over that
    topic. Entirely was an absolute horrifying setting in my view, nevertheless noticing the
    expert manner you processed that took me to weep for fulfillment.

    I am just happier for the support and then expect you
    really know what an amazing job you’re putting in instructing the rest via your
    websites. Probably you have never come across any of us.
