1951 to present; Further moves and takeover
After the Second World War Frank Cooper's bought the site of the ice rink and Majestic Cinema west of the railway stations on the north side of Botley Road.[7] A new factory was built on the site and the company moved production there from Park End Street.
The company also manufactured mint sauce and horseradish sauce in a separate building at the side of the Bulstake stream. In the summer months, they replaced marmalade production with fruit jams, such as strawberry. Both marmalade and jam could also be purchased in “fancy jars”, two sizes of china jars with matching lids, painted with designs such as “crinoline ladies”.
Brown & Polson Ltd. bought Frank Cooper's in 1964 and moved production away from Oxford in 1967,[7] but retained the "Oxford" name for the marmalade.
Some time between 1984 and 1987[4] Frank Cooper's again leased 84 and 85 High Street, running 85 as a museum[9] and 84 as a shop until about 1990.[4] Since 2001, 84 High Street has been marked by an Oxfordshire Blue Plaque commemorating Sarah Cooper's inception of Oxford Marmalade.[10]
The former factory at 27 Park End Street (now part of Frideswide Square) survives and is a listed building.[6] It is now called "The Jam Factory" and houses an arts centre, restaurant, and bar.[11]
Heinz purchased Frank Cooper's in 1997. It was later sold to Rank Hovis McDougall which was acquired by Premier Foods in 2006. The brand was again sold in 2012, this time to Hain Celestial Group.
