Christian Jacobæus
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 1933 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. 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 Royal Swedish Academy of Engineering Sciences 1957–88, serving as its vice chairman 1979–81, and a member of the ...

Stockholm, Sweden
Stockholm () is the capital and largest city of Sweden as well as the largest urban area in Scandinavia. Approximately 980,000 people live in the municipality, with 1.6 million in the urban area, and 2.4 million in the metropolitan area. The city stretches across fourteen islands where Lake Mälaren flows into the Baltic Sea. Outside the city to the east, and along the coast, is the island chain of the Stockholm archipelago. The area has been settled since the Stone Age, in the 6th millennium BC, and was founded as a city in 1252 by Swedish statesman Birger Jarl. It is also the county seat of Stockholm County. For several hundred years, Stockholm was the capital of Finland as well (), which then was a part of Sweden.

Hans Christian Jacobæus
Hans Christian Jacobaeus (29 May 1879 – 29 October 1937) was a Swedish internist born in Skarhult. In 1916 he became a professor at the Karolinska Institutet in Stockholm. From 1925 until his death in 1937, he was a member of the Nobel Prize Committee. Jacobaeus was an important figure in regards to modern laparoscopy and thoracoscopy. In 1910 he is credited with performing the first thoracoscopic diagnosis with a cystoscope, being used on a patient with tubercular intra-thoracic adhesions. In 1910, he published an article titled ''Über die Möglichkeit die Zystoskopie bei Untersuchung seröser Höhlungen anzuwenden'' (The Possibilities for Performing Cystoscopy in Examinations of Serous Cavities) in the journal ''Münchner Medizinischen Wochenschrift''. He also did pioneer work involving abdominal endoscopy, which he called laparoscopy. The term "laparoscopy" was introduced into clinical medicine and is used up to now although Jacobaeus initially called the procedur ...

Engineers From Stockholm
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professiona ...

Fellow Members Of The IEEE
A fellow is a concept whose exact meaning depends on context. In learned or professional societies, it refers to a privileged member who is specially elected in recognition of their work and achievements. Within the context of higher educational institutions, a fellow can be a member of a highly ranked group of teachers at a particular college or university or a member of the governing body in some universities (such as the Fellows of Harvard College); it can also be a specially selected postgraduate student who has been appointed to a post (called a fellowship) granting a stipend, research facilities and other privileges for a fixed period (usually one year or more) in order to undertake some advanced study or research, often in return for teaching services. In the context of research and development-intensive large companies or corporations, the title "fellow" is sometimes given to a small number of senior scientists and engineers. In the context of medical education in No ...

Queueing Theorists
Queue areas are places in which people queue (first-come, first-served) for goods or services. Such a group of people is known as a ''queue'' (British usage) or ''line'' ( American usage), and the people are said to be waiting or standing ''in a queue'' or ''in line'', respectively. (In the New York City area, the phrase ''on line'' is often used in place of ''in line''.) Occasionally, both the British and American terms are combined to form the term "queue line". Examples include checking out groceries or other goods that have been collected in a self service shop, in a shop without self-service, at an ATM, at a ticket desk, a city bus, or in a taxi stand. Queueing is a phenomenon in a number of fields, and has been extensively analysed in the study of queueing theory. In economics, queueing is seen as one way to ration scarce goods and services. Types Physical History The first written description of people standing in line is found in an 1837 book, '' The French Revo ...

Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include "Richie", "Dick", "Dickon", " Dickie", "Rich", "Rick", "Rico", "Ricky", and more. Richard is a common English, German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish.
