Viscount Marchwood, of Penang and of Marchwood in the County of Southampton, is a title in the Peerage of the United Kingdom. It was created in 1945 for the businessman and Conservative politician Frederick Penny, 1st Baron Marchwood. He had already been created a baronet, of Marchwood in the county of Southampton, in the Baronetage of the United Kingdom on 19 June 1933, and Baron Marchwood, of Penang and of Marchwood in the County of Southampton, in 1937, also in the peerage of the United Kingdom.
As of 2022[update] the titles are held by his great-grandson, the fourth Viscount, who succeeded his father in that year. The third Viscount was educated at Winchester College and served in the Royal Horse Guards, before a career in the drinks industry, first at Cadbury Schweppes, then as managing director of Moet et Chandon.[1]
