I first met Hanns in 1977 and soon learnt of his extraordinary ability as a researcher. He became a friend as well as a mentor providing enthusiasm for my own research. I watched closely over the years how his research uncovered details of the association of the benzodiazepines and GABA and delineated the structural composition of the GABAA receptor associated with the action of individual drugs such as antianxiety and antiepileptic agents. His work produced many important contributions to medicine notable of which was the discovery of the first benzodiazepine antagonists, which are now routinely used in clinical practice. But for me his most important contribution was the discovery of the benzodiazepine receptor. During this time, my group uncovered a novel receptor for GABA and my progress in this work was encouraged and enhanced by discussions with Hanns.
