John Dewar Sr.

John Dewar (6 January 1805 – 22 January 1880), often referred to as John Dewar Sr, was a Scottish whisky distiller and businessman best known as the founder of the Scotch whisky firm John Dewar & Sons. Starting from a wine and spirits shop in Perth in the mid-19th century, he was among the first merchants to sell blended Scotch whisky in branded glass bottles, laying the foundations for the Dewar's blend that his sons later turned into an international brand.

On his death, Thomas and John took over the management of the business.

Death Dewar died in 1880, aged 74. He was interred in Perth's Wellshill Cemetery. His wife survived him by twenty years and was buried beside him.
