Memorial Page for Gazi Yaşargil (née Mahmut Gazi Yaşargil)

Mahmut Gazi Yaşargil (born 6 July 1925 in Lice, Turkey; died 10 June 2025 in Stäfa, Switzerland) was a Turkish-Swiss neurosurgeon and medical researcher. He decisively advanced microneurosurgery and changed the treatment of aneurysms, vascular malformations, brain tumours and other diseases of the brain.

Education in Turkey, Germany and Switzerland

Yaşargil grew up in the young Turkish Republic and went to Germany for medical studies after school. The Second World War interrupted this path; in 1945 he continued his studies at the University of Basel and graduated in 1950. Switzerland became the centre of his professional life. In Zurich he began neurosurgical training under Hugo Krayenbühl in 1953.

Zurich and the view through the microscope

At the University Hospital Zurich, Yaşargil worked for decades as a physician, researcher, teacher and later head of neurosurgery. In the 1960s he deepened his microsurgical work on fine blood vessels in the United States. Back in Zurich, he systematically used the operating microscope, new instruments and precise routes of access in brain surgery. This made operations possible that had previously seemed barely reachable or too risky.

Method and attitude

Yaşargil understood brain surgery as close observation of anatomical structures. The microscope showed him sulci, spaces, vessels and natural corridors that could spare healthy tissue. His instruments, techniques and textbooks shaped generations of neurosurgeons. His multi-volume works on microneurosurgery became working foundations for the field.

Teaching and international work

After decades in Zurich, Yaşargil moved to the United States and joined the University of Arkansas for Medical Sciences, where he continued to operate, research and teach. He trained many physicians from different countries and remained a reference figure in neurosurgery into old age. In 1999 the Congress of Neurological Surgeons recognised his work across the period from 1950 to 1999.

Farewell

Gazi Yaşargil died in Stäfa on Lake Zurich on 10 June 2025, a few weeks before his 100th birthday. He was 99 years old. His name remains connected with surgery centred on precision, patience and respect for the structure of the brain.
