A true Yorkshireman, Pyrah graduated in Medicine from Leeds University in 1924, followed by an MSc in Physiology, and was elected to the Honorary Consultant Staff of the Leeds General Infirmary in 1934. His rather reserved and unassuming manner belied an extremely competent and respected general surgeon. In addition to his general work, Pyrah maintained an interest in surgical research, and later urological research, trying to combine basic science, in particular biochemistry, with clinical practice, and in 1938 was appointed Director of Surgical Research at Leeds University.
An important turning-point in Pyrah's career came in 1950 when he decided to forsake general surgery and to concentrate his efforts in urology, again with a particular emphasis on urological research. In 1956 he was appointed to the first Professorial Chair in Urological Surgery in Britain, at Leeds University, setting a standard of excellence that attracted urological trainees and scientists from around the globe. His personal enthusiasm led to the Medical Research Council's establishing in the same year a research unit, of which he became Honorary Director, into the chemical pathology and causation of renal stone disease.
Further study into bladder malignancy was followed by pioneering work on renal dialysis and the creation of a successful artificial kidney. Under his guidance the Wellcome Wing was established at the General Infirmary in 1959, dedicated to clinical research, which was founded on grants from the Wellcome Foundation, the University and the Endowment Fund of the United Leeds Hospital together with significant local support.
Pyrah was appointed Weild Lecturer at the Faculty of Physicians and Surgeons in Glasgow in 1955, the Ramon Guiteras Lecturer to the American Urological Association in 1957 and the Litchfield Lecturer at Oxford University in 1959. Also in 1959 he was awarded the St Peter's Medal by the British Association of Urological Surgeons and in 1975 the Honorary Gold Medal of the Royal College of Surgeons of England, in recognition of his immense surgical achievements.
Outside medicine Pyrah was an avid reader, a more than useful tennis player and a keen ornithologist. In addition he was an accomplished pianist who had considered turning professional in earlier years. British urology can only be thankful that the course he took has left us with such an exciting future.
