By the time of his death in 1859, he had won international fame for his scientific discoveries, his observations of Native American peoples and his detailed descriptions of the flora and fauna of the 'new continent'. The first to draw and speculate on Aztec art, to observe reverse polarity in magnetism and to discover why America is called America, his writings profoundly influenced the course of Victorian culture, causing Darwin to reflect: 'He alone gives any notion of the feelings which are raised in the mind on first entering the Tropics'.

    It was walking that first caused rifts between us in my sulky teenage years, and walking that brought us back together later on; and this ‘ghost’ of Dad has been walking at my elbow since his death, as I have ruminated on his great love of walking, his prodigious need to do it – and how and why I walk myself.”The January Man is set over one calendar year as, month by month, region by region, Christopher Somerville walks the routes that remind him of his father. As he travels the country – from the River Severn to the Lake District, the Norfolk Coast to the Isle of Foula off the west coast of Shetland – he describes the history, wildlife, landscapes and people he passes, down back lanes and old paths, in rain and fair-weather.This exquisitely written account of the British countryside both inspires us to don our boots and explore the 140,000 miles of footpaths across the British Isles, but also illustrates how, on long-distance walks, we can come to an understanding of ourselves and our fellow walkers. Over the hills and along they by-ways, Christopher Somerville finally finds the man behind his father’s modest, buttoned-up, wartime facade.
