PERSONALITY OF THE MONTH Jeff Dinitz Professor, University of Vermont
The Bulletin has to start this vignette with an apology to Jeff. By a fluke, Jeffs name was left off the list of members of the Council of the ICA. This omission has now been corrected - see page 1 of this issue of the Bulletin.  Jeff is a member of Council for a three-year term from 1993 to 1996.

In 1992, Jeff Dinitz and Doug Stinson, published Contemporary Design Theory, A Collection of Surveys (John Wiley and Sons, Inc.). This book was reviewed in Volume 9 of the Bulletin (page 9), and continues to receive a lot of well deserved acclaim; Jeff and Doug seem to have filled a real need
with this timely and outstanding work.

Last year, graph theorists received electrifying news from Jeff on the famous problem of the number of one factorizations of K_12 . Here is an extract from the email message of Monday, September 20, 1993 at 16:04:28.

Theorem. There are 526,915,620 non-isomorphic one-factorizatio…

EULER MEDALS FOR 1993
In announcing the Euler Medallists for 1993, a reminder about the qualifications for the Medals is in order. Up to two Euler Medals per year may be awarded. A recipient must be a Fellow of the ICA and must have made a particularly distinguished lifetime career contribution to research in Combinatorics; the Euler Medal is not meant to recognize one specific achievement. Furthermore, a recipient should still be active in research.

By majority vote of the ICA Council, 1993 Euler Medals have been awarded to Claude Berge, one of the world's most distinguished graph theorists, and Ronald Graham, a research combinatoricist of enormous breadth, depth, and influence. Members of the ICA may be interested in the extremely brief summaries of their research careers that follow.

Ronald L. Graham. Ph.D., University of California (Berkeley), NSF Fellow and Woodrow Wilson Fellow.

STEFAN ZNAM 1936-1993 Alex Rosa, J. Siran
Štefan Znám, Professor of Mathematics at Comenius University in Bratislava and a leading Slovak graph theorist and number theorist, passed away suddenly July 17, 1993.

After obtaining his first degree in mathematics in 1959, Štefan Znám started his scientific career working in number theory. His results on covering systems of congruences have become a classic. Later in the sixties, partly through working on Zarankiewicz's problem, he became more and more interested in graph theory which was at the time becoming a rapidly expanding discipline. His main interest was in extremal problems, but very soon he was contributing substantial papers in other areas, such as graph decompositions. He was an author or co-author of well over 50 original papers· on these and various other subjects. Several of these papers, including one which settles completely the spectrum problem for maximal partial Steiner triple systems, are yet to a…

1993 Annual General Meeting of The Institute of Combinatorics and its Applications
The 1993 Annual General Meeting of the Institute of Combinatorics and its Applications took place at 8:00 p.m. on Wednesday, July 7, in the Westminster Theatre of Keele University, during the Fourteenth British Combinatorial Conference. Since the Conference organizers had graciously scheduled the meeting into the Conference agenda, there was a large attendance of members of the ICA, as well as additional visitors.

Professor Ronald Read, from the Council of the Institute, took the chair.

Financial Report for the Year 1992.
This report was presented by Professor R.G. Stanton. The Financial Report was accepted (motion by Nash-Williams, seconded by Grannell). A copy of the report is appended to this account of the AGM.
