My brother, Christopher Hoskin, who has died suddenly and unexpectedly aged 49, was both a talented mathematician and programmer as well as a keen naturalist, contributing significantly to the protection of the natural environment in Oxfordshire.
Born in Plymouth, Devon, to Colin, a shipyard supervisor and latterly civil servant, and Rosalind (nee Wakeham), a shop worker, Christopher grew up in Bearsden, Glasgow, and later in Somerset, where he progressed through the state school system, latterly at Frome community college, before accepting a place at Oxford, becoming the first member of his family to attend university.
