Agner Krarup Erlang (1 January 1878 – 3 February 1929) was a Danish mathematician, statistician and engineer, who invented the fields of traffic engineering[1] and queueing theory.[2]By the time of his relatively early death at the age of 51, Erlang had created the field of telephone networks analysis.
