Professor John Reilly has been a keen birder all his life, visiting over fifty countries and observing nearly half the world's bird species. In the late 1970s, he led several pioneering bird and wildlife tours to the Arctic island of Spitsbergen. Since developing an interest in avian evolution, he has concentrated on tracking down and photographing species that have important evolutionary stories to tell, birds that provide the key characters for each of the book's chapters.
After graduating in biochemistry and then medicine, John worked as a consultant haematologist in Sheffield for 25 years. In addition to teaching, lecturing and clinical work, he led an active research programme into the causes and treatment of various blood cancers, authoring over 200 scientific articles in peer-reviewed journals.
John's medical and scientific career, and time spent as a bird guide, enable him to present complex scientific concepts to the non-specialist ― whether in the field of leukaemia or the evolution of birds.
In 2014, he retired from the NHS to concentrate on travelling and writing. This career change was encouraged by the success of his first book, Greetings from Spitsbergen: Tourists at the Eternal Ice (2009) published by Tapir Academic Press. In 2013 he established Svalbard Press, with the aim of publishing the histories of different countries as revealed by their early postcards. The first volume in the series, Spitsbergen's Early Postcards: an annotated catalogue, was published in 2014. Further volumes on Papua New Guinea and Greenland are in preparation.
