"Remembering a Pioneer in Endocrinology and Champion of Public Health"

Dr. Henry Kaye (Kaye) Ibbertson, who passed away on July 12, 2018, at the age of 91, was an Emeritus Professor of Endocrinology at the University of Auckland and a former Head of the Department of Endocrinology at Auckland Hospital. His career was marked by groundbreaking research, a commitment to education, and a profound impact on the healthcare landscape of New Zealand and internationally.

After graduating from the University of Otago in 1951 and gaining early experience at Auckland Hospital, Dr. Ibbertson pursued postgraduate training at prestigious institutions in London, including the Hammersmith Hospital under Professor Russell Fraser and the Royal Free Hospital with Dr. Shelia Sherlock. This advanced training equipped him with the expertise to revolutionize endocrinology upon his return to New Zealand.

Returning to New Zealand in 1963, Dr. Ibbertson took on the role of heading the Radioisotope Unit at Auckland Hospital. He then established the Department of Endocrinology in the mid-1960s. As both Head of Department and Professor of Endocrinology at the University (1970-1992), he trained numerous physicians who went on to hold prominent positions in New Zealand and across the globe.

Dr. Ibbertson's contributions to the Royal Australasian College of Physicians were substantial and long-lasting. He became a Member in 1954 and a Fellow in 1961, actively shaping the college's direction and standards in New Zealand.

His involvement included:

Convenor of the sub-committee for Medical Research (1967-1973)
Member of the New Zealand Board of Censors (1974-1979)
Councillor for the College (1972-1975)
Member of the Scientific and Continuing Education sub-committee (1973-1983)

These roles demonstrate his commitment to medical research, education, and the continuous improvement of healthcare practices within the region. Further highlighting his dedication, he also served on the Medical Research Council of New Zealand, the Child Health Research Council, and the Auckland Medical Research Foundation, solidifying his position as a key figure in advancing medical knowledge and patient care.

Impacting Lives: From Nepal to New Zealand

Dr. Ibbertson's influence extended far beyond the walls of hospitals and universities. His collaborative work with Edmund Hillary in Nepal, beginning in 1966, addressed the critical issue of iodine deficiency among the Sherpa population. These journeys, spanning until 1972, led to the implementation of an iodinization program that dramatically improved the health and well-being of this community.

Back in New Zealand, Dr. Ibbertson spearheaded the establishment of a growth hormone replacement program for children with deficiencies. He also conducted early and important research on the treatment of Paget's disease and osteoporosis using bisphosphonates, pioneering treatments that are now widely used.

His passion for medical history, demonstrated by his founding membership and leadership of the Auckland Medical History Society, and his instrumental role in establishing the Ernest and Marion Davis Memorial Library and Lecture Halls, further highlight his commitment to fostering knowledge and education. His legacy continues to inspire medical professionals in New Zealand and Australia.
