David MacKay was a true polymath, whose knowledge and contributions spanned important, wide-reaching areas of engineering. He made significant developments in fields including machine learning, efficient communication, and sustainable energy.

David developed a way to correct signal interference, which is now used in digital broadcasting and magnetic storage of information, such as on computer hard drives. He also advanced the field of machine learning by improving artificial neural networks. Furthermore, he invented Dasher, an assistive software application that enables communication in any language with any muscle of the body.

In 2008, he published a book on sustainable energy, which is regarded as a go-to text for energy policy and was praised worldwide. From 2009–2014, he was the Chief Scientific Advisor to the UK Department of Energy and Climate Change.

Sir David MacKay FRS died on 14 April 2016.
