Florence Nightingale & Why she is important to Statistics

Florence Nightingale12 May 2020 is the 200th anniversary of Florence Nightingale’s birth. Nightingale (12 May 1820-13 August 1910) was a British social reformer and statistician, and the founder of modern nursing. She came to prominence while serving as a manager and trainer of nurses during the Crimean War, in which she organised care for wounded soldiers. In 1860, Nightingale laid the foundation of professional nursing with the establishment of her nursing school at St Thomas' Hospital in London. It was the first secular nursing school in the world and is now part of King's College London.

In her lifetime, Nightingale published work concerned with spreading medical knowledge. She was a pioneer in the development of statistical graphics to visually represent data and developed diagrams called coxcombs and used them to illustrate the various causes of death during the Crimean War.

ISI turns 135 years on 24 June 2020

Adolphe QueteletThe origins of the International Statistical Institute (ISI) can be traced back to a series of International Statistical Congresses, the first of which was convened by Adolphe Quetelet in 1853 in Brussels. The ISI was formally founded in 1885 during a meeting held to celebrate the Jubilee of the London Statistical Society. The initial 81 members were the elite of that era’s statisticians in government and academia. They established our first statutes, and our first half-century was a period of general stability. Learn more about the ISI’s history as we publish articles over the course of 2020 on a special web page dedicated to the ISI’s 135 years.


Though the ISI has a rich history, we are also very relevant in the international statistical community of the 21st century. The ISI World Statistics Congresses (WSCs) take place once every two years in a different country and are usually in partnership with the country’s National Statistics Office. The WSCs are the ISI’s flagship event when activities of the ISI, our Associations and Committees happen. About 2,500 delegates come from all corners of the world to participate in a varied scientific programme with many satellite meetings and short courses scheduled before or after the WSCs. Also read more about the ISI’s mission and objectives, as well as our many membership options. We hope you join our membership community!
