For many, the rise of the infographic is linked to the digital age. Yet a new exhibition will show scientists and statisticians have used images to explain data for centuries, including Edmund Halley and Florence Nightingale, who used a diagram to help drive through health reform.
Beautiful Science: Picturing Data, Inspiring Insight opens tomorrow in the British Library’s Folio Society Gallery. It marks the first time the organisation has ever had a science exhibition and seeks to highlight how important a role picturing data plays in the scientific process.
Johanna Kieniewicz, lead curator of the show, said that “while the mass amount of data and abilities to animate it is much more advanced, in some ways we’re similar. Going back a long time people saw diagrams as tremendous potential to communicate scientific ideas.”
The items on display run from a 17th century illustrated diagram to a moving infographic of currents in the world’s oceans compiled by NASA.
Dr Kieniewicz said there were parallels with developments today and, in particular, the Victorian age. She said: “We are in an era of big data, but there was also an explosion in data back then, particularly related to vital statistics and climate. They too were trying to reconcile how to work with the information and communicate it to the public.”

Ernst Haeckel was inspired by the ideas of Charles Darwin and sought to devise trees organising all life on Earth
In her seminal ‘rose diagram’, Florence Nightingale demonstrated that far more soldiers died from preventable epidemic diseases (blue) than from wounds inflicted on the battlefield (red) or other causes (black) during the Crimean War (1853-56)
This unusual map of 1685 illustrates ocean currents as understood at the time based on the observations of explorers and mariners. Though necessarily conjectural in many ways, it highlights the remarkable effort made by early cartographers to make sense of an accumulation of data from such reports without the visualisation tools we have today
Epidemic Planet is based upon the Global Epidemic and Mobility model, which researchers used to accurately forecast the 2009 pandemic influenza outbreak
In these diagrams, epidemiologist and statistician William Farr plotted cycles of temperature and cholera deaths for 1840-50. He notes that the circular form and colours make ‘the diagram represent the facts in a striking manner to the eye’. At the time, Farr believed that cholera, now known to be caused by water-borne bacteria, was spread by miasma or ‘bad air,’ sourced from evaporation of the Thames. Although this hypothesis was incorrect, Farr left an important legacy. He set up the first national system for collecting statistics, advocated a data-driven approach to public health, and utilised innovative graphic methods to communicate that data.

Among the items on display is Nightingale’s “rose diagram” from 1858. “Most people know Nightingale as a nurse and the lady of the lamp, but she was also a very hard-nosed statistician,” Dr Kieniewicz said of the first woman to be elected to the Royal Statistical Society.
Her diagram showed that significantly more deaths in the Crimean War were down to poor hospital conditions than battlefield wounds.
Dr Kieniewicz said: “It was a means of communicating what was going on in the hospitals. She put it on pamphlets and sent it to government ministers and anyone who would listen to her. It showed the importance of the visual image.”
The rose diagram was “very political” the curator said. “She was using it to try and drive through health reforms.”
The curators set out to show that in the age of advancing technology that the challenge of presenting data in visually appealing ways is not a new one.
Dr Kieniewicz said: “As big data is becoming such a topic of huge interest, we wanted to show the important connections between the past and the present.” She added that centuries-old data “is now being used to inform cutting edge science”.
The earliest piece in the show is Robert Fludd’s Great Chain of Being, a visual representation of a hierarchically ordered universe from 1617.
The curator revealed that the Met Office still used data from log books used on East India Company clipper ships to test their climate models. Dr Kieniewicz said: “The idea is to understand weather patterns of the present and future we need to be tied into what has happened in the past.”
Eberhard Werner Happel drew a map in 1685 charting the oceans’ currents. Sitting opposite is Nasa’s moving infographic charted off satellite readings and buoys.
The exhibition also looks at William Farr and John Snow’s use of statistics to study a cholera epidemic and compares it to computerised models of a flu pandemic in 2009, which animates how it spread around the world.
As well as health and weather the exhibition’s third strand is the tree of life, which uses data to map evolution
“Data visualisation is a technique with a rich and surprisingly long history,” Clive Izard, head of exhibitions at the British Library, said.Reuse content
