David Wishart gained a PhD from the School of Computer Science at the University of St. Andrews. He entered the Government Statistical Service as a statistician at the Civil Service Department, rising to Director of Statistics at the Scottish Office. He also developed a statistical package widely used and commercially available for cluster analysis called “Clustan”.
On his retirement from the Scottish Office, he returned to St Andrews as a Research Fellow at the School of Management. He used Clustan to classify single malt whiskies by flavour, and constructed ten groups in which the whiskies all taste similar. This research led to a book, published in 2002, titled: Whisky Classified Choosing Single Malts by Flavour. This book has been translated into ten languages, with the tenth anniversary edition being published in 2012
