Frank Harary
Frank Harary (March 11, 1921 – January 4, 2005) was an American mathematician, who specialized in graph theory. He was widely recognized as one of the "fathers" of modern graph theory. Harary was a master of clear exposition and, together with his many doctoral students, he standardized the terminology of graphs. He broadened the reach of this field to include physics, psychology, sociology, and even anthropology. Gifted with a keen sense of humor, Harary challenged and entertained audiences at all levels of mathematical sophistication. A particular trick he employed was to turn theorems into games—for instance, students would try to add red edges to a graph on six vertices in order to create a red triangle, while another group of students tried to add edges to create a blue triangle (and each edge of the graph had to be either blue or red). Because of the theorem on friends and strangers, one team or the other would have to win. Biography Frank Harary was born in New Yo ...

Klaus Wagner
Klaus Wagner (March 31, 1910 – February 6, 2000) was a German mathematician known for his contributions to graph theory. Education and career Wagner studied topology at the University of Cologne under the supervision of who had been a student of Issai Schur. Wagner received his Ph.D. in 1937, with a dissertation concerning the Jordan curve theorem and four color theorem, and taught at Cologne for many years himself. In 1970, he moved to the University of Duisburg, where he remained until his retirement in 1978. Graph minors Wagner is known for his contributions to graph theory and particularly the theory of graph minors, graphs that can be formed from a larger graph by contracting and removing edges. Wagner's theorem characterizes the planar graphs as exactly those graphs that do not have as a minor either a complete graph ''K''5 on five vertices or a complete bipartite graph ''K''3,3 with three vertices on each side of its bipartition. That is, these two graphs are the only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Michigan Institute For Social Research
The Institute for Social Research (ISR) is the largest academic social research and survey organization in the world, established in 1949. ISR includes more than 300 scientists from a variety of academic disciplines – including political science, psychology, sociology, economics, demography, history, anthropology, and statistics. The institute is a unit that houses five separate but interdependent centers which conduct research and maintain data archives. In 2021, Kathleen Cagney became the first woman in its history to be named Director of the institute. History In 1946, the sociologist and economist Rensis Likert, creator of the Likert scale, and six colleagues from his wartime work at the Bureau of Agricultural Economics, including Angus Campbell, Leslie Kish, and George Katona, formed the Survey Research Center (SRC) at the University of Michigan. The center gained credibility in its field due to a survey conducted in October 1948, when Campbell and Robert L. Kahn a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Professor Emeritus
''Emeritus/Emerita'' () is an honorary title granted to someone who retirement, retires from a position of distinction, most commonly an academic faculty position, but is allowed to continue using the previous title, as in "professor emeritus". In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished performance (usually in the area of research) awarded selectively on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title. The term ''emeritus'' does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them. In descriptions of deceased professors emeriti listed at U.S. universities, the title ''emeritus'' is replaced by an indication of the years of their appointments, except in Obituary, obituaries, ...
