Origins of telephone network theory
In the course of researching the history of applied mathematics in the US, one of the problems I came across was the problem of telephone network design. Phone calls couldn't be predicted reliably, and where one of the first industrial applications of probability theory. Below is a citation network of the early theoretical work on the subject, color-coded with yellow nodes for the USA, cyan for the UK, and red for Denmark. Gray nodes are review articles, rather than original research.
