Sir David John Cameron MacKay FRS FInstP FICE[9][7] (22 April 1967 – 14 April 2016)[1][11] was a British physicist, mathematician, and academic. He was the Regius Professor of Engineering[12] in the Department of Engineering at the University of Cambridge[13] and from 2009 to 2014 was Chief Scientific Adviser to the UK Department of Energy and Climate Change (DECC).[14] MacKay was the author of the book Sustainable Energy – Without the Hot Air.[3][15][16]

Education[edit]

MacKay was educated at Newcastle High School and represented Britain in the International Physics Olympiad in Yugoslavia in 1985,[17] receiving the first prize for experimental work. He continued his education at Trinity College, Cambridge, and received a Bachelor of Arts degree in Natural Sciences (Experimental and theoretical physics) in 1988.[1] He went to the California Institute of Technology (Caltech) as a Fulbright Scholar, where his supervisor was John Hopfield.[10] He was awarded a PhD in 1992.[18][19][9]

Career and research[edit]

In January 1992 MacKay was appointed the Royal Society Smithson Research Fellow at Darwin College, Cambridge, continuing his cross-disciplinary research in the Cavendish Laboratory, the Department of Physics of the University of Cambridge. In 1995 he was made a University Lecturer in the Cavendish Laboratory. He was promoted in 1999 to a Readership, in 2003 to a Professorship in Natural Philosophy and in 2013 to the post of Regius Professorship of Engineering.[20]

MacKay's contributions[21][22][23][24] in machine learning and information theory include the development of Bayesian methods[25] for neural networks,[26] the rediscovery (with Radford M. Neal) of low-density parity-check codes,[4] and the invention of Dasher,[5] a software application for communication especially popular with those who cannot use a traditional keyboard.[27] He cofounded the knowledge management company Transversal.[28] In 2003, his book Information Theory, Inference, and Learning Algorithms[29] was published.

His interests beyond research included the development of effective teaching methods and African development; he taught regularly at the African Institute for Mathematical Sciences in Cape Town from its foundation in 2003 to 2006. In 2008 he completed a book on energy consumption and energy production without fossil fuels called Sustainable Energy – Without the Hot Air. MacKay used £10,000 of his own money to publish the book, and the initial print run of 5,000 sold within days.[30] The book received praise from The Economist,[31] The Guardian,[30] and Bill Gates, who called it "one of the best books on energy that has been written."[32][33] Like his textbook on Information theory, MacKay made the book available for free online.[34] In March 2012 he gave a TED talk on renewable energy.[35]

MacKay was appointed to be Chief Scientific Advisor of the Department of Energy and Climate Change, United Kingdom, in September 2009.[14] In October 2014, at the end of his five-year term, he was succeeded by John Loughhead.[36]

Awards and honours[edit]

MacKay was elected a Fellow of the Royal Society (FRS) in 2009.[7] His certificate of election reads:

In the 2016 New Year Honours, MacKay was appointed a Knight Bachelor "for services to Scientific Advice in Government and Science Outreach", and therefore granted the title sir.[37][38]

Personal life[edit]

David MacKay was born the fifth child of Donald MacCrimmon MacKay and Valerie MacKay.[1] His elder brother Robert S. MacKay FRS (born in 1956) is Professor of Mathematics at the University of Warwick. David was a vegetarian.[39]

He married Ramesh Ghiassi in 2011.[1] They had a son and a daughter.[11]

Illness and death[edit]

MacKay was diagnosed with inoperable stomach cancer (malignant adenocarcinoma) in July 2015,[9] for which he underwent palliative chemotherapy, a process he documented in detail on his public personal blog.[40][41] He died in the afternoon of 14 April 2016.[42][43][44][45] He is survived by his wife and two children.[11]
