A brief account of an adventurous journey in the neurosciences. A tribute to the contributions of Dr. Kresimir Krnjević.

Krnjević, was an active member of the Croatian Peasant Party who, after the beginning of King Aleksandar's dictatorship and the formation of the Kingdom of Yugoslavia in 1929, moved his family to Geneva. During the 10 years that the family spent in Switzerland, Dr. Krnjevic became fl uent in French. The family returned to Zagreb in 1939, only to leave again in 1941, when the Germans invaded Yugoslavia. As a member of the Yu-goslav Government in exile, his father moved to England, but Dr. Krnjevic and his sister were sent for safety to Capetown, South Africa, where he learned the English language. After fi nishing high school, he moved to Great Britain at the beginning of 1944 and started his tertiary education in the medical school at Edinburgh University , graduating MBChB in 1949. At this point, he made the career decision to undertake PhD. training in the physiology department of the university under the supervision of David Whitteridge Dr. Krnjevic received an Honours BSc. in 1951 and PhD in 1953. His fi rst scientifi c publication was a proceedings paper in the Journal of Physiology (1952, 118 3P-4P), titled " The perfusion of the frog sciatic nerve with electro-lyte solutions " 1. This was followed by two full papers in 1954 on the perineural sheath as a diffusion barrier around peripheral nerves. All of these initial publications were under solo authorship. Post-doctoral studies took Dr. Krnjević and his wife, Jeanne, to the University of Washington in Seattle (1954-1956), where he continued his studies on Na and K ions in degenerating cat nerves; and where he also recorded age-dependent changes in somatosensory responses in the cortex of kittens. Dr. Krnjević then undertook a second post-doctoral position in the where he initiated research with R. Miledi on adrenaline and the failure of neuromuscular transmission and other publications on neuromuscu-lar transmission. Both also collaborated with D. R. Curtis on a project to record intracellularly from sacral motoneurons. While in Canberra, he
