"The great fields of gerontology and geriatrics need a great and imaginative encyclopedia - and this is it!"
-Robert N. Butler, MD, President and CEO, International Longevity Center

" For two decades The Encyclopedia of Aging has provided current, authoritative accounts of what is known about the multiple dimensions of human aging. In a timely 4th edition of this pioneering work, hundreds of scientists and scholars update the rapidly evolving knowledge of how and why adults age and the factors that affect their aging well."
-George Maddox, PhD, Duke University Center for the Study of Aging and Human Development

"It is indeed a privilege to give this hearty endorsement to this latest edition of The Encyclopedia of Aging a resource for anyone who wants up-to-date, dependable information about any aspect of our ever-increasing knowledge about aging."
-T. Franklin Williams, MD, Professor of Medicine Emeritus, University of Rochester, and Former Director, National Institute on Aging, National Institutes of Health

"This is a mighty book...a treasure-house of knowledge...a must for every medical library."
-The Lancet

Richard Schulz, PhD, is Professor of Psychiatry, Psychology, Epidemiology, Sociology, and Health and Rehabilitation Sciences, and Director of the University Center for Social and Urban Research, at the University of Pittsburgh. He is also Associate Director of the Institute on Aging at the University of Pittsburgh. He received his AB in Psychology from Dartmouth College and his PhD in Social Psychology from Duke University. He is the recipient of several honors, including the Kleemeier Award for Research on Aging from the Gerontological Society of America, and the Developmental Health Award for Research on Health in Later Life from the American Psychological Association. He also served as Editor of the Journal of Gerontology: Psychological Sciences. He has spent his entire career doing research and writing on adult development and aging. Funded by numerous NIH institutes for more than two decades, his research has focused on social-psychological aspects of aging, including the role of control as a construct for characterizing life-course development, and the impact of disabling late life disease on patients and their families. This body of work is reflected in publications, which have appeared in major medical (JAMA, NEJM), psychology (Psychological Review, Psychological Bulletin, JPSP), and aging (Journal of Gerontology, Psychology and Aging, JAGS, AJGS) journals.

Linda S. Noelker, PhD, joined the Benjain Rose Institute in 1974 as an applied aging researcher and is currently the Senior Vice President for Planning and and Organizational Resources. In that capacity, she oversees the Research Institute and the Institutional Advancement and the Advocacy and Public Policy Departments. She received her MA and PhD from Case Western Reserve, where she is an Adjunct Professor of Sociology. She is also the Editor-in-Chief of The Gerontologist, the leading journal in applied aging research, practice, and policy. Dr. Noelker holds leadership positions in the American Society of Agin and the Gerontological Society of American and recently received the 2005 American Society on Aging Award for exemplary contributions to the field of aging.

Kenneth Rockwood, MD, FRCPC, is Professor of Medicine (Geriatric Medicine & Neurology), Kathryn Allen Weldon Professor of Alzheimer Disease Research, and the Director of the Geriatric Medicine Research Unit at Dalhousie University. He is a Canadian Institute of Health Research (CIHR) Investigator and a member of the CIHR Institute of Aging Advisory Board. He has a longstanding interest in delirium, dementia, and frailty.

Professor Rockwood is author of more than 200 peer-reviewed scientific publications, and five books. He is a staff physician in the Department of Medicine at the Queen Elizabeth II Health Sciences Centre, Halifax, Nova Scotia.

Currently, he is the principal investigator in the Video Imaging Synthesis of Treating Alzheimer's disease (VISTA) study, an investigator-initiated national, multi-center project to identify and track novel treatment effects in patients with mild to moderate Alzheimer's disease who are treated with galantamine, an anti-dementia medication.

Kenneth Rockwood is a native of Newfoundland and became a Doctor of Medicine at Memorial University in 1985. He is married to an internationally recognized scientist in the Faculty of Medicine - Susan Howlett, Professor of Pharmacology, and together they have two teenage sons, Michael and James.

Richard L. Sprott, PhD, is Executive Director of the Ellison Medical Foundation. He began his undergraduate studies at Franklin and Marshall College and- completed them at the University of North Carolina at Chapel Hill, earning a BA with honors in Psychology. After receiving his PhD in Experimental Psychology (Behavior Genetics) at UNC he went on to a postdoctoral fellowship in Behavior Genetics at the Jackson Laboratory in Bar Harbor, Maine. Following two years of teaching at Oakland University, Dr. Sprott returned to The Jackson Laboratory where he conducted a research program on single gene influences on behavior and the interaction of aging variables with those genes.

After a decade in Maine, Dr. Sprott moved to the National Institute on Aging where he directed the Institute's programs on the Biology of Aging. A major focus of his career has been the development of animal models for aging research. He developed a nationwide research program on biomarkers of aging and the effects of dietary restriction on longevity. He is the author of a large number of books and articles. He is an internationally recognized expert on animal model development and plays an active role in model development in countries around the world. He is the Past President of the International Biogerontological Resource Institute (IBRI) in Friuli, Italy.

Dr. Sprott left the National Institute on Aging in 1998 to become the first Executive Director of the Ellison Medical Foundation, created to support basic biological and biomedical research on aging, and recently expanded to provide similar support for basic research on infectious diseases of importance in the developed and developing worlds. The Ellison Medical Foundation is the largest private foundation source of funding for the biology of aging, providing about $28,000,000 per year in grant funds for aging research, and $12,000,000 for infectious disease research.
