  Alfred Bray Kempe Quick Info Born 6 July 1849 Kensington, London, England Died 21 April 1922 London, England Summary Alfred Kempe  published a false "proof" of the four colour theorem in  1879  which stood until Heawood showed the mistake  11  years later. The 'proof' is however still the basis for the computer aided proof discovered  100  years later. Full story : https://mathshistory.st-andrews.ac.uk/Biographies/Kempe/

  David Pike (Vice-President of ICA) was just elected as president-elect of the Canadian Mathematical Society (his two-year term as president will start one year from now).  David was also named as one of seven new Fellows of the CMS:  https://cms.math.ca/news-item/canadian-mathematical-societys-2021-class-of-fellows-announced/ CANADIAN MATHEMATICAL SOCIETY’S 2021 CLASS OF FELLOWS ANNOUNCED The Canadian Mathematical Society is pleased to announce the 2021 Class of Fellows consisting of 7 members from the Canadian mathematical community. The Fellowship recognises CMS members who have made excellent contributions to mathematical research, teaching, or exposition; as well as having distinguished themselves in service to Canada’s mathematical community. Induction to the 2021 Class of Fellows was based upon nominations, reception of the David Borwein Distinguished Career Award or the Graham Wright Award for Distinguished Service, or reception of any other CMS prize or award fo...

 C. R. Rao was born on  September 10, 1920, in  Huvina Hadagali, India.  He earned several degrees:  M.A. degree in mathematics at the Andhra University in Waltair, Andhra Pradesh (1941), with first class and first rank. M. A. degree in statistics from Calcutta University in Kolkata, West Bengal (1943), with first class, first rank, and record marks unbeaten till now; further with a gold medal. Ph.D. at Cambridge University, UK (1948). Sc.D. by peer review of published work, Cambridge University, UK (1965). He is most famous for his work in statistics, but he did make major contributions to design theory.   Between 1952 and 2001, he had 51 PhD students and while many are statisticians, several are design and graph theorists. He was elected an Honorary Fellow of the ICA with the citation "as the world's leading expert in statistical design theory" in 1995. In September 2020, the Indian Statistical Institute Retired Employees' Association Pays Homage to ...

 https://www.quantamagazine.org/mathematicians-answer-old-question-about-odd-graphs-20210519/ Mathematicians Answer Old Question About Odd Graphs A pair of mathematicians solved a legendary question about the proportion of vertices in a graph with an odd number of connections. For decades, mathematicians have debated a simple question about graphs and the number of connections they have. Consider a graph G and a subgraph H such that all the vertices of H have odd degree.  The minimum size of such an H is now known.  Now, using arguments an undergraduate math student could have come up with,  Asaf Ferber  of the University of California, Irvine and  Michael Krivelevich  of Tel Aviv University have finally provided the answer in the form of a proof  posted in March .
