Leonard Hayflick is Professor of Anatomy at the University of California San Francisco School of Medicine. He has been a member of the faculty there since 1988.

Dr. Hayflick earned his Ph.D. from the University of Pennsylvania. He then completed a postdoctoral fellowship in Texas, under the guidance of Prof. Charles Pomerat. After returning to Philadelphia, he worked for ten years at the Wistar Institute as an Associate member, and spent two years at the University of Pennsylvania as an Assistant Professor of Medical Research.

Dr. Hayflick’s research is well-known in many fields, including cell biology and the development of virus vaccines.

He discovered in 1962 that normal cells from humans and animals are not able to reproduce as much as was thought at the turn of this century. The Hayflick Limit was named after this phenomenon, which overturned an old dogma dating back to the early twentieth century. It also focused attention on cells as the primary location for age changes.

Dr. Hayflick serves on numerous scientific and public boards and committees at the national and international level. He has served on or is currently on the Editorial Boards for more than ten journals, including the International Journal \”EXPERIMENTAL GEOLOGY\”.

He has been a member of 20 scientific and professional organizations, where he held many high-ranking positions, including that of President of the Gerontological Society of America. He was also a founding Member of the National Institute on Aging and Chairman of the Executive Committee. He also served as Chairman of the Scientific Review Board of American Federation for Aging Research, where he also held the positions of Vice President and Member of the Board of Director.

Dr. Hayflick, author of \”How and Why we Age\”, was also a Genentech consultant for 25 years. He was responsible for developing the technology used to grow animal cells in fermentation vessels in which the majority of their blockbuster biological products worth billions of dollars were produced.
