Endre Czeizel (3 April 1935 – 10 August 2015) was a Hungarian physician, clinical geneticist and university professor. Over several decades he combined clinical practice, population research and teaching to address congenital abnormalities and their prevention. He is widely remembered for research that strengthened the evidence linking periconceptional vitamin interventions with reduced risk of certain birth defects.
Career and research focus
Czeizel trained and practised as a medical doctor and later specialized in human genetics and genetic epidemiology. He held academic appointments and led clinical and population studies that examined causes of congenital anomalies and possible preventive measures. At various times he collaborated with national and international health organizations, including work with the World Health Organization, on strategies to lower birth defect prevalence.
Contributions and impact
His research emphasized primary prevention—intervening before or during early pregnancy to reduce risk. Czeizel contributed to investigations of nutritional supplementation and genetic counseling as tools to prevent neural tube and other congenital defects. Findings from his and related studies contributed to the broader evidence base used by clinicians and public health authorities when recommending folic acid and multivitamin use around conception.
Teaching, publications and legacy
As a professor he supervised clinical training and published extensively in the fields of medical genetics and epidemiology. Colleagues and students noted his role in translating genetic knowledge to practical prevention programs and in raising public and professional awareness about birth defect prevention.
Endre Czeizel died on 10 August 2015 in Budapest from leukemia at age 80. His work remains cited in discussions of congenital anomaly prevention and the role of periconceptional nutrition in reproductive health.
