By her 30s, Scottish virologist June Almeida had already developed new techniques to better visualize and identify viruses using an electron microscope.
She was not only a pioneer of virus imaging: Almeida also played a pivotal role in identifying the first human coronavirus, the same type of virus with tiny spokes as SARS-CoV-2, the virus that is causing the COVID-19 pandemic.
In 1964, while Almeida was working at St. Thomas's Hospital Medical School in London, she started to collaborate with other scientists on research about the common cold. One sample of a nasal swab, known as B814, was of particular interest to researchers. They found that type of virus could transmit common cold symptoms to volunteers, but researchers were unable to identify it and grow it in routine cell culture.
The research team sent samples of B814 to Almeida to study. With virus imaging, she described it as an influenza-like virus, but not exactly the same. Under a microscope, the B814 had a halo-like structure and was eventually named corona, the Latin word for crown.

Almeida identified the first coronavirus — and produced first visualizations of other viruses like rubeola, or measles. But her work in the field of virology has gone largely uncelebrated.
Now, 13 years after her death, the COVID-19 pandemic has made her work more relevant than ever.
Hugh Pennington, an emeritus professor of bacteriology at the University of Aberdeen in Scotland, used to work with Almeida at St. Thomas' Hospital Medical School in London. He spoke with The World's host Marco Werman about Almeida’s research and legacy.
Oh, I knew her very well. We were good friends. June spent most of her time at the electron microscope down in the medical school basement in the dark. She got into this kind of empire very jealously. I was working on quite different things upstairs, but we published a paper together on models of viruses and how you could simulate them using X-rays. I knew June very well, and I regard her as one of my most important scientific mentors. She was really a very interesting person to collaborate with and somebody who gave me an enormous start in my career.
She was really very good at having a network of people that she collaborated with, like David Tyrrell from the Common Cold Research Unit in Salisbury, who was trying to isolate common colds and identify them. He had this virus and he said, "Well, June is the obvious person to see what it is." So that's where her breakthrough occurred when she saw the virus and she said, "A-ha, here is a new group of viruses," identified by the spikes with the knobs that we're all very familiar with now.
Of course, thereafter, coronaviruses didn't seem to be terribly important. They didn't cause serious illnesses, so they remained as curiosities for years until SARS came along and now, of course, COVID-19. She had a hand in giving the virus the name coronavirus.
And she would have been amused that her name is now common currency everywhere. I don't think she would be going around claiming credit. She would just say, "Well, that was a piece of work I did. How nice."

I don't know. She'd done some really good work on other viruses. I suppose she didn't seek publicity. She didn't need to. She had the links that she developed with other scientists. So people came to see her, bringing her material to look at.
What June was doing was really important work, but it wasn't the sort of work that gets on the news in the evening on television or anything like that. She was just discovering things.
I have a scar on my arm, which is one of my June Almeida legacies. She and I agreed that it would be worth trying to grow a human wart virus, which was a virus she was interested in. And so she persuaded me to have a bit of my skin taken off on my arm to try and grow the human wart virus in a rather similar way to the way that the coronavirus is being grown.
Unfortunately, we were not successful. But I have this badge of honor, which, you know, I guess, I see June Almeida every morning. She was good at persuading people to do things. She persuaded me to have a hole cut on my arm. So suppose that tells the story really quite nicely, what June was like.
