    Hermona Soreq President of The Scientific Advisory Board of The International Symposia on Cholinergic Mechanisms informed us of the loss of Alexander George Karczmar ('Niki' to many), our elected ISCM Honorary President, who passed away peacefully at his Chicago home at the age of 100. For many of us Alex was the essence of cholinergic signalling, and personified its versatile power to send messages between tissues and organs and to connect between body and soul. Born and raised in Poland, he immigrated to the United States as a young person, and spent the bulk of his research career at the Loyola University Medical Centre in Chicago. Alex initiated his studies on the cholinergic system shortly after the second world war. His work at that time focused on the mechanism of action and damage to organs and tissues of the highly toxic anti-cholinesterase nerve agents, and he served as a consultant to the US military in developing therapeutic approaches to protect both soldiers and civilians against them. Subsequently, Alex's research interests widened, and much of his work was devoted to studying the meaning of 'self' and its association with the cholinergic signaling pathways..He made seminal contributions to cholinergic research, won numerous honours and awards, and was always outspoken and decisive in expressing his views. Alex's key efforts focused on the impact of the cholinergic system on what and who we are, and he attributed great value to his role in instigating and maintaining the triennial series of International Symposia on Cholinergic Mechanisms. He was a founding member of these meetings, an active participant for over 30 years, and, in recognition of his seminal role, was elected Honorary President of the International Advisory Board in our China meeting several years ago. Alex called his colleagues in cholinergic research 'cholinergikers', and he himself was the ultimate 'cholinergiker'! His many friends and colleagues will cherish his memory, and remember him fondly.

Doctor Travel Awards from scientific colleagues and family friends of "Doc." can fund five young investigators at $1,000 each, which will cover their registration funds, housing and perhaps a bit of travel for the next Cholinesterase meeting in Elche, Spain next September. The stipulations are that the investigators are young: student, postdoc, beginning faculty without funds. There must also be a reasonable geographic distribution of the awardees with attention accorded to those applicants without access to funding.

    The tribute to Buphendra P Doctor by Palmer Taylor is available here: BPDoctor.pdf. He added: After consultation with Ellen Doctor and past associates of B. P. Doctor at Walter Reed Army Institute of Research and elsewhere, we feel that an appropriate memorial in his name would be the development of a fund for travel of young investigators attending International Meetings of the Cholinesterases. Priority would be accorded to students, fellows and beginning faculty lacking grant funds or other means for travel to scientific meetings. Those awarded travel funds would be expected to present at either poster sessions or workshops scheduled for the meeting. B.P. Doctor had an abiding interest in international meetings, and believed that research on the cholinesterases and related targets required global perspectives and cooperation. He felt that research in cholinesterases should meet the needs of third world countries where misuse and accessibility to pesticides are high, as well as in built environment locations with controlled ventilation systems where substantial populations of individuals could be exposed through terrorist activities. Those colleagues wishing to contribute should send checks to: Pharmacology Education and Research Foundation, P.O. Box 144, 9700 Gilman Drive,La Jolla, CA 92093-5010. Individual checks and accompanying letters should be labeled as the B. P. Doctor Memorial Travel Award Fund. The Pharmacology Education and Research Foundation has been categorized as a foundation by the United States Internal Revenue Service. All donations will be acknowledged as support for a tax-free foundation. The Organizing Committees of the respective International Cholinesterase Meetings shall award funds to the applicants in relation to the funds available. The Doctor family will be apprised of the fund donors, the fund financial base, and the awardees.

Being in an avian science department, he worked extensively with bird cholinesterases. His larger endeavors toward environmental protection were at the forefront.
