Douglas Graham Altman FMedSci (12 July 1948 – 3 June 2018) was an English statistician best known for his work on improving the reliability and reporting of medical research and for highly cited papers on statistical methodology.

His first job was in the Department of Community Medicine, St Thomas’s Hospital Medical School, London.

[7] Altman's publications on statistical education, many co-authored with his long-standing collaborator Martin Bland, are well known among the medical profession, being noted for their practical relevance and clarity.

In 2015 Altman was awarded a lifetime achievement award by the BMJ, where he was credited by the editor, Dr Fiona Godlee, with having "done more than anyone else to encourage researchers to fully report what they actually did, warts and all, rather than letting the best be the enemy of the good or, worse, pretending that research is perfect".

[13] Altman was also editor in chief of Trials, a Fellow of the Academy of Medical Sciences and the Royal Statistical Society.
