Dr. Karolis (Karl) Lederis
RSC Fellow, Academy of Sciences
Affiliation: University of Calgary
Deceased Date: 2007-03-17
Dr. Karl Lederis did pioneering studies on the brain neurohormones of the posterior pituitary gland, or neurohypophysis, in vertrabrate animals to claify the mechanisms of neurohormone storage and secretion. More recently he discovered a unique and important action of the neurohypophysial neurohormone oxytocin in energy metabolism. He has been a leading figure in determining the structure of the peptide neurohormones secreted from the tail-end or urophysis of the spinal cord of fishes. Studies on these special peptides have led to unique findings on the role of peptides in the regulation of blood pressurein fishes and mammals. Synthesis of one of the urophysial peptides (urotensin I) revealed its high potency in the secretion adrenocorticotropin, smilar to the mammalian brain peptide corticotropin releasing hormone (CRH). More recently, collaboration with Director and members of the Institute for Molecular Neurobiology at the University of Hamburg (Germany) led to the determination of precursors and genes and receptors for fish corticotropin releasing factors (CRF).

Deceased Date: 2012-04-17
Geoffrey Bosdin Leech is a Cordilleran geologist on the staff of the Geological Survey of Canada. He is noted for a breadth of interests which embraces virtually all the sciences that contribute to modern geology. His reports reflect mature comprehension of such diverse disciplines as palaeontology, structure, sedimentation, mineralogy, geochemistry, and isotope geology. Conclusions based on penetrating and balanced interpretation of all these aspects of geology are earning for Dr. Leech a reputation as a thorough and philosophical scientist. HIs keen interest in the history of Western Canada gives promise of contributions to the Society in the field of the humanities as well as in geology.

Dr. William C. Leggett
RSC Fellow, Academy of Sciences
Affiliation: Queen's University
Keywords: Marine ecology, fisheries, biological oceanography, ecosystem dynamics
Deceased Date: 2026-02-13
Dr. William Leggett, Principal and Vice-Chancellor of Queen's University at Kingston, has made important contributions in the field of the relation between the physical environment and the life and behaviour of fish, both marine and freshwater, in particular fish migration, population dynamics and production. He pioneered the emphasis on abiotic variables as first-rank determinants of annual variations in production, a considerable advance on the biotic models formerly used in prediction. His work has married the disciplines of meteorology, physical oceanography and biology, thus opening new fields of understanding and prediction.
Dr. Heinz Lehmann
RSC Fellow,
Affiliation: McGill University
Keywords: Psychopharmacology
Psychiatric neurology
Psychiatric diagnosis
Psychiatric therapy
Psychiatric history
Deceased Date: 1999-04-07
Dr. Lehmann has had probably more sustained experience of hospital psychiatry than any other psychiatrist in the Americas. He initiated the clinical investigation of chlorpromazine in this continent and his work has been largely the foundation of the revolution in psychiatric treatment and in the structure and function of mental hospitals.
For 15 years Dr. Lehmann has led in the methodology of objective and quantitative experimental studies of pschotropic drugs in relation to their physiological, psychological, and behavioural effects. He and his collaborators were awarded the McNeil Award for the best paper at the 1969 meeting of the Canadian Psychiatric Association.
Dr. Lehmann has served as Visiting Professor at many universities in the U.S.A. and Canada and takes active part in public discussions on methodological problems of psychiatric disorders. He is a former President of the American College of Neuropsychopharmacology and currently President of Collegium Internationale Neuropsychopharmacoligicum, a member of the NIMH Study Group to evaluate U.S. research grant applications, Membre de la Conseil des Recherches Médicales de Québec and member of the federal commission of inquiry into the non-medical use of drugs.
James Leith
RSC Fellow, Academy of the Arts and Humanities
Affiliation: Queen's University
Keywords: Enlightenment, revolution, allegory, symbolism, propaganda
Deceased Date: 2018-05-15
Professor Leith's principal interest is France in the eighteenth century and the dominant occurrence of that century, the Revolution. The hitherto scarcely used material he has found cast new light on the topic of which he has made his researches the focus - the place of the arts, major and minor, in revolution. This topic has drawn him to study revolution in Russia and in China, as well as to such subjects as education in eighteenth century Europe and the religious views of Voltaire.
Leith's work has earned him wide recognition among European scholars, especially in France, where he is a familiar figure at the Sorbonne and in "les Archives Nationales".
Dr. Raymond Lemieux
RSC Fellow,
Affiliation: University of Alberta
Keywords: Carbohydrate chemistry
Molecular recognition
Synthesis of oligosaccharides
Glycoproteins
Conformational analysis
Deceased Date: 2000-07-22
Dr. Lemieux has developed a widely acknowledged reputation through his work in the carbohydrate field. By applying modern electronic concepts of theoretical organic chemistry to the carbohydrates he has been able to explain plausibly certain hitherto mystifying reactions. It has also allowed him to anticipate the properties of 1,2-anhydro-oc-D-glucopyranose, and this has made it possible for him to achieve the first purely chemical synthesis of three of the most important disaccharides found in nature, i.e. maltose, trehalose and sucrose. Dr. Lemieux has also developed a novel method of oxidation of unsaturated compounds which is proving very useful and will undoubtedly find wide application in organic research.
