Beginning in 1981, The Dorothy R Havemeyer Foundation began sponsoring workshops of particular interest to equine researchers and clinicians. Dr. Douglas F. Antczak, Havemeyer PI, lead the charge with a series of workshops on Lympoho Alloantigens in the horse.

The superior content and ability of the attendees led to over 145 workshops with more planned for 2022 and beyond. These workshops have enabled summer fellows, veterinary students and residents, clinicians in private practice and researchers from industry to meet on a common ground and learn from one another.

Foundation President Gene M. Pranzo Receives AAEP's Leadership Award

Mr. Gene M. Pranzo, CEO and President of The Dorothy R. Havemeyer Foundation, has been named the recipient of the George Stubbs Award for leadership of the Foundation and its mission to improve the general health and welfare of horses. The George Stubbs Award recognizes the contributions made to equine veterinary medicine by individuals other than veterinarians.

Mr. Pranzo has been instrumental in developing the Foundation from its inception in 1979 to its role in scientific research, workshops, and publications on equine reproduction, behavior, and infectious diseases and on the creation of an equine genetic map.

“I see it as an award to the Foundation rather than to me,” says Pranzo. “It is, without doubt, a tribute to the work of our Principal Investigators and the outstanding workshops the Foundation has held year after year. And I am particularly pleased that recognition comes to the Foundation in the year of its silver anniversary.”

The award was presented at the Presidents’ Luncheon during the American Association of Equine Practitioners Annual Convention on December 7, 2004, in Denver, Colorado.

Foundation Principal Investigator Sue McDonnell Receives AAEP's Prestigious George Stubbs Award

Ms. Sue McDonnell, Ph.D., a Dorothy Russell Havemeyer Foundation Principal Investigator has been named the recipient of the George Stubbs Award for her “revolutionary equine behavioral research.” The George Stubbs award recognizes the contributions made to equine veterinary medicine by individuals other than veterinarians.

Through her innovative research methods, McDonnell has provided monumental insight into the understanding of equine behavior, physiology, and welfare. As a Havemeyer Foundation Principal Investigator, she maintains a semi-feral herd of ponies at the University of Pennsylvania Veterinary School at New Bolton Center for the study of equine social behavior and development of undomesticated environment.

McDonnell’s pioneering research in reproductive physiology has enabled her to implement proven methods for resolving problematic behavior in stallions and mares. Continually promoting compassion for horses, McDonnell has worked with the AAEP to address welfare issues related to the pregnant mare urine industry in the United States and Canada.

The award was presented at the President’s Luncheon during the American Association of Equine Practitioners 57th Annual Convention on November 22, 2011, in San Antonio, Texas.

Foundation Principal Investigator Douglas F. Antczak inducted into Hall of Fame

Douglas F. Antczak, Principal Investigator and the Dorothy Havemeyer McConville Professor of Equine Medicine was inducted into the University of Kentucky Equine Research Hall of Fame on October 25th, 2009 by the Gluck Equine Research Foundation.

Dr. Antczak has served as a Havemeyer Principal Investigator since the early 1980s and has led and participated in numerous Foundation workshops. He actively participated in the Foundation’s Horse Genome Project from the very beginning. Antczak is the Dorothy Havemeyer McConville Professor of Equine Medicine at the James A. Baker Institute for Animal Health, College of Veterinary Medicine at Cornell University, where he joined the staff in 1979. In 1994, he became the director of the Baker Institute for Animal Health, a post he held for 15 years until mid-2009.

Dr. Daniela Bedenice brings a wonderful range of expertise to the Havemeyer Foundation. In addition to her camelid care, Dr. Bedenice takes great pride in her work with foals and adult horses. Dr. Bedenice grew up in rural Germany, where she trained and cared for many horses, and even accompanied her local veterinarian on nearly two years’ worth of farm calls. Soon after, she moved to the United States, became a Havemeyer fellow under Dr Mary Rose Paradis, earned her board certification in both veterinary internal medicine and emergency and critical care,  and joined the faculty at the Cummings School. Dr Bedenice was named a PI with the Foundation in 2020, following the retirement of Dr Paradis. Her primary research interest is in Non-invasive pulmonary function testing (horses, dogs, camelids).

Dr. Douglas F. Antczak

Smiley face

Since 1981 the Havemeyer Foundation has had a strong working relationship with the Baker Institute for Animal Health, a unit of Cornell’s College of Veterinary Medicine. The Institute’s equine research program has been lead by Dr. Douglas F. Antczak, Dorothy Havemeyer McConville Professor of Equine Medicine.

Dr. Antczak developed strong research programs in equine immunology, reproduction, and genetics. For this research Dr. Antczak developed a herd of purpose-bred horses selected for homozygosity at the Major Histocompatibility Complex. These horses are a unique genetic resource – the donor horses for the Bacterial Artificial Chromosome library and the Whole Genome Sequence of the Horse Genome Project are members of this herd. The Baker Institute horse herd is stabled at the Dorothy Havemeyer McConville Barn, a historic agricultural building on the Cornell campus.

In 2009 Dr. Antczak was inducted into the University of Kentucky’s Equine Research Hall of Fame.  In 2010, Dr. Antczak was the recipient of the Distinguished Veterinary Immunologist Award, a prize awarded only once every three years by the Veterinary Immunology Committee of the International Union of Immunological Societies. In 2018, Dr. Antczak received one of the five inaugural Lifetime Achievement Awards from the International Equine Reproduction Symposium.

Dr. Mary Rose Paradis

Smiley face

The Dorothy Havemeyer Foundation chose Mary Rose Paradis to become one of their primary investigators in 1990. As primary investigator in Neonatal and Geriatric diseases of horses, her mandate was to conduct research, train summer students/fellows, and conduct workshops to expand veterinary knowledge in these fields.  Many students, fellows, interns, residents and colleagues were involved in this research. Some have stayed in academia while others have continued careers in private practice. Many patients received care through the Foundation that would otherwise have gone untreated.  We celebrated that good work with a retrospective of what was accomplished, and where the people are now in their careers. Dr Paradis has been crucial to furthering the mission of the Havemeyer Foundation.

Prof. William "Twink" Allen


Renowned equine reproduction expert “Twink” Allen died at the age of 80 after a short illness.

Allen had been a well-known figure in England’s thoroughbred hub, Newmarket, for many years and is the father of Catherine Dettori, wife of jockey Frankie.

He was particularly known for his work in assisted reproductive technologies, carrying out pioneering methods of embryo recovery and transfer in mares and studies of hormones and ultrasonography. Twink began his prolific association with the Havemeyer foundation in (need year).

Equine Veterinarians Australia described Allen as a “godfather of equine reproduction”.

“So many of our routine procedures in horse breeding are with thanks to Twink. He has left a great legacy.”

A graduate of veterinary medicine from the University of Sydney, he was a director of the Thoroughbred Breeders’ Association Equine Fertility Unit, a professor at the University of Cambridge and held numerous other research positions. He was awarded a CBE in 2002, Fellowship of The Royal College of Veterinary Surgeons (FRCVS) by thesis, elected to the Polish Academy of Sciences, Honorary Doctorates from the Universities of Krakow, Gent and Helsinki and was elected to the Hall of Fame for Equine Research in the US, and received a Lifetime Achievement Award from the International Symposia of Equine Reproduction Committee.

Allen retired from the University of Cambridge in 2007, and was the honorary director at the Paul Mellon Laboratory of Equine Reproduction in Newmarket from 2008 to 2015, when he became director of the Equine Reproduction Laboratory, Sharjah Equine Hospital, in the UAE.

In a biography on the Society for Reproduction and Fertility, Allen described several career highlights, including carrying out the first embryo transfers in horses and donkeys, and the development and practical application of both surgical and non-surgical methods of embryo recovery and transfer in the mare. He described how, in 1974, with Franseca Stewart and Alan Trownson, “the successful transport of six horse embryos in the oviducts of two rabbits by car to Krakow in Poland in 1974 for transfer to recipient mares there, with the birth of three live foals in 1975”.

Allen was also behind the early development and practical application of the technique of transrectal ultrasonography in thoroughbreds for the accurate visual assessment of follicular growth, ovulation and corpus luteum development and for the early accurate diagnosis of single and twin pregnancy and early pregnancy failure.

Allen was also among those responsible for organizing and running of the First International Symposium of Equine Reproduction in Cambridge in July, 1974
