Jensen persuaded Erlang to join the telephone company and find a solution to the problem of waiting times for telephone calls. His papers were prepared in a very brief style and can be difficult to understand without a background in the field. At its basic wgner, an Erlang represents the continuous use of a single voice path. He developed his theory of telephone traffic over several years. FCR currently supports more than 70 clients and employs over krrup, colleagues.

His thinking went further by finding how many telephone operators were needed to handle a given volume of calls.

In he gave a formula for loss and waiting time which was soon used by telephone companies in many countries including the British Post Office. He published his first paper on these problems The theory of probability and telephone conversations in His studies at Copenhagen were in mathematics and natural science. If you continue without changing these settings you agree to this.

During this time he kept up his interest in mathematics, and he received an award for an essay on Huygens ‘ solution of infinitesimal problems krarhp he submitted to the University of Copenhagen.

While attending eelang of the Mathematical Association, he met the chief engineer of the Copenhagen Telephone Company, who persuaded Erlang to use his mathematical skills to benefit his employer. He was an associate of the British Institution of Electrical Engineers. He used his summer holidays to travel abroad to France, Sweden, Germany and Great Britain, visiting art galleries and libraries.


His early work in scrutinizing the use of local, exchange and trunk telephone line usage in a small community to understand the theoretical requirements of an efficient network led to the creation of the Erlang formulawhich became a foundational element of modern telecommunication network studies. Even though his natural inclination was toward scientific research, he proved to have excellent teaching qualities.

By studying a village telephone exchange he worked out a formula, now known as Erlang’s formula, to calculate the fraction of callers attempting to call someone outside the village that must wait because all of the lines are in use.

Back then, most telephone exchanges used human operators and cord boards to switch telephone calls using jack plugs.

Agner Krarup Erlang, Danish mathematician, c 1915.

These and other notable papers were translated into English, French and German. At meetings of the Mathematical Association he met Jensen who was then the chief engineer at the Copenhagen Telephone Company. He passed his final school exam with distinction when he was just 14 and become a schoolteacher when he was only 15!

At this time one of his favourite subjects was astronomy and he liked to write poems on astronomical subjects. He was often to be seen in the streets of Copenhagen, accompanied by a workman carrying a ladder, which was used to climb down into manholes. When he finally attended the University of Copenhagen inhe was so poor that the school supplied him with food and lodgings while he studied there.

A errlang years later, erpang studied mathematics and natural science at Copenhagen University, where he developed a fascination for problems of geometry. Over the next 7 years he taught in various schools. He devised new calculation methods for certain forms of tables. Just type and press ‘enter’. Agner spent his early school days with them at his father’s schoolhouse.


His mother was Magdalene Krarup from an ecclesiastical family and had a well known Danish mathematician, Thomas Fincke, amongst her ancestors. Understanding the Social Significance of Scientific Discovery.

He returned to Lonberg and taught at his father’s school for two years. His formula for the probability of loss was accepted by the British Post Office as the basis for calculating circuit facilities.
