History of Meetings

The Society’s origins date back to 1971, when a Working Group led by I. Szám, D. Müting and V. Bräutigam organized an International Symposium on Ammonia Metabolism. Held in Budapest in May 1972, this first symposium featured Sir Hans Adolf Krebs’ presentation of the newly discovered urea cycle. The well-attended event provided a great opportunity to discuss different aspects of ammonia metabolism and ammonia-related disorders. From that date onwards, the meeting has become a popular triannual event.

Andy-Blei-Lectures/The Gallery of Honour


In commemoration of Dr. Andy Blei, a great clinician scientist, who contributed to ISHEN enormously and who passed away in 2008, prematurely, the ISHEN board in 2014 decided to establish the Andy-Blei-Lectures as part of the ISHEN meetings. Outstanding members of the ISHEN community are asked to give these lectures as a sign of esteem.
 
The Andy-Blei lecture was given by:
 
Roger Butterworth, 2014 in London, UK

Piero Amodio, 2019 in Williamsburg, USA
Vicente Filipo, 2021 in Padova, Italy
