Sir Matthew Decker, 1st Baronet (1679 – 18 March 1749) (Dutch: Mattijs Decker) of Richmond Green in Surrey, was a Dutch-born English merchant and economist who served as a Member of Parliament for Bishop's Castle in Shropshire from 1719 to 1722. He was a governor of the South Sea Company from 1711 to 1712, and a Director of the East India Company from 1713 to 1743. His published works show him as "such a strong supporter of the doctrine of free trade as to rank as one of the most important forerunners of Adam Smith",[3] proposed amongst other measures, to abolish customs duties and replace them with a tax upon houses, to abolish the duty on tea replacing it with a licence duty on households wishing to consume it, and to repeal import duties and bounties in general. At his house in Richmond, he amassed a large collection of art, including many Dutch paintings, which later formed the core of the collection of the Fitzwilliam Museum, founded by his grandson. He was a pioneer in the growing of exotic fruits in England, including pineapple and lemon, in his heated greenhouses at Richmond.
