Cooper was a merchant involved in the herring trade and appears regularly in Yarmouth’s corporation books after his appointment as a member of the Forty-Eight in 1595.
Cooper was elected to his first Parliament in December 1620, and was allowed expenses of 10s. a day for the journey to the capital, and 6s. 8d. a day while in London.
Cooper frequently travelled to London on Yarmouth business. In 1622 he secured letters patent to enable Yarmouth to export 4,000 tons of beer duty free and devote the profits towards repair of the haven.
Cooper fell seriously ill in 1625, and it was not until March 1627 that he was declared to be ‘fit and capable of employment in the town’s affairs’.
