S. S. Srikhande . His friends call him "Shrik", but he is also often referred to as SSS. The development of to-day's very strong group of Indian researchers in Combinatorics is due largely to the pioneering research of R.C. Bose and S.S. Shrikhande. One of the few times that Combinatorics made the pages of the New York Times was when Bose, Parker, and Shrikhande disproved the famous Euler conjecture that there were no pairs of orthogonal Latin squares of side 4n+2. Shrik is such an innovative research worker in Design Theory that it is difficult to single out particular achievements, but many colleagues would cite his work on the extension of quasi-residual designs for values of lambda greater than 2. From his citation as one of the first Honorary Fellows, BICA (1), 1991. From his well-cited wikipedia page: Sharadchandra Shankar Shrikhande (born 19 October 1917) is an Indian mathematician with distinguished and well-recognized achievements in combinatorial mathema...

Bernhard Hermann Neumann . One of the great researchers of our time in  the theory of groups, Professor Neumann has trained a score of other group  theorists and, as dean of Australian mathematicians, has provided strong  stimulus to the development of all areas of mathematics in Australia. A  mathematician of very broad knowledge and interests, he has always been  extremely friendly to combinatorics, serves as the Honorary Editor of the  Australasian Journal of Combinatorics, and has actively promoted and  contributed to the Combinatorial Mathematics Society of Australasia. His  work in groups has led to increased recognition of the importance of the  underlying group of a combinatorial structure. From his citation as one of the first Honorary Fellows, BICA (1), 1991. From his well-cited wikipedia page: Bernhard Hermann Neumann AC FRS (15 October 1909 – 21 October 2002) was a German-born British-Australian mathematician who was a lea...

Derrick Henry Lehmer . The wide scope of Professor Lehmer's research in Combinatorics, Number Theory, Computational Techniques, and the interconnections that exist among these areas can best be grasped by looking at the three volumes of his "Selected Papers" that appeared in 1981. Much of modern combinatorics is heavily dependent on on the computer, and Professor Lehmer, fallowing in a family tradition, has been a godfather to the development of computer algorithms, generating computational results, and getting other researchers to recognize the importance of computation. From his citation as one of the first Honorary Fellows, BICA (1), 1991. From his well-cited wikipedia page: Derrick Henry "Dick" Lehmer (February 23, 1905 – May 22, 1991) was an American mathematician who refined Édouard Lucas' work in the 1930s and devised the Lucas–Lehmer test for Mersenne primes. Lehmer's peripatetic career as a number theorist, with him and his wife taking nume...

Haim Hanani . No one has contributed more to the development of our knowledge of designs than Professor Hanani. His paper showing that the necessary conditions for the existence of Steiner Quadruple Systems are also sufficient was a landmark in design theory that settled a question that had been open for over a century, and his papers on the existence of designs with block sizes 4 and 5 are probably the most frequently cited papers in the subject His constructions of designs have combined, in a unique fashion, his talents for systematic , thorough, and careful organization with his talents for ingenious and innovative developments. From his citation as one of the first Honorary Fellows, BICA (1), 1991. From his well-cited wikipedia page: Haim Hanani (September 11, 1912 as Chaim Chojnacki–April, 1991) was a Polish-born Israeli mathematician, known for his contributions to combinatorial design theory, in particular for the theory of pairwise balanced designs and for the proof of an ...
