Christian Jacobaeus

Anton Christian Jacobæus (1911 in Stockholm, Sweden–1988) was a Swedish electrical engineer, known for his contributions to teletraffic engineering, especially in the design of the modern crossbar switch used for telephone switching.

Jacobæus graduated from the Royal Institute of Technology (KTH) in 1934 with a master's degree in electrical engineering. In 1935 he went to work for L. M. Ericsson, where he would spend his entire professional career. [K. V.

Ericsson] In 1950 he received his doctorate in electrical engineering, also from KTH. His dissertation entitled "A study of congestion in link systems" became instrumental in the efficient design of crossbar switches. He became technical director in 1950, then senior vice president from 1963 until his retirement in 1976. He then continued to serve as a consultant to the company's management.He was a member of the Swedish Academy of Sciences 1957–88, serving as vice chairman 1979–81.In 1979, he was awarded the IEEE Alexander Graham Bell Medal.
