Agner Krarup Erlang (1 January 1878 – 3 February 1929) was a Danish mathematician, statistician and engineer, who invented the fields of traffic engineering and queueing theory. By the time of his relatively early death at the age of 51, Erlang had created the field of telephone networks analysis.
For the next two years he taught alongside his father. A distant relative provided free board and lodging, and Erlang prepared for and took the University of Copenhagen entrance examination in 1896, and passed with distinction.
He graduated in 1901 with an MA and over the next 7 years taught at several schools.
Erlang worked for the CTC (KTAS) from 1908 for almost 20 years, until his death in Copenhagen after an abdominal operation. He was an associate of the British Institution of Electrical Engineers. == Contributions == While working for the CTC, Erlang was presented with the classic problem of determining how many circuits were needed to provide an acceptable telephone service.

One researcher from Bell Telephone Laboratories is said to have learned Danish to study them. The British Post Office accepted his formula as the basis for calculating circuit facilities. In 1946, the CCITT named the international unit of telephone traffic "the Erlang".
