Who was John Graunt?

Robert Friis (Chair, Health Sciences Department, California State University, Long Beach ) gives expert video advice on: How did John Snow impact epidemiology?; How did John Graunt change epidemiology? and more...

John Graunt is important to epidemiology because he is known as the father, the Columbus, of biostatistics. What he did was to examine vital statistics, date, births and deaths in London. And he was able to show certain regularities in the data, for example the excess of male births over female births that can be observed today in modern vital statistics records. He was among the first to do this and to make this particular contribution.
