It is with great sadness that we report that Dan Brown, who had been battling cancer for some time, died on Tuesday April 24, 2012, aged 89.
Dan was an outstanding nucleotide chemist who in 1951, with the future Nobel Laureate Alexander Todd, determined definitively the chemical linkage in DNA and RNA and who was one of the pioneers in the chemistry of nucleic acids. He was made a Fellow of the Royal Society in 1982.
