area, nurseries were prominent in the local economy; the Cox's Orange Pippin apple was first raised in Colnbrook (not then within Slough) around 1825, and the dianthus "Mrs Sinkins Pink" was first raised at some point between 1868 and 1883 by John Sinkins, the master of the Eton Union Workhouse, which lay in Slough. In the mid-19th century, the only major employer apart from the brickfields was James Elliman, who started as a draper in Chandos Street. In 1847, he changed business and manufactured his Elliman's Embrocation and Royal Embrocation horse liniment at factories in Wellington Street and Chandos Street. Elliman became a major benefactor to the town, and is remembered today in the names of local roads and schools. In September 1851, William Thomas Buckland, an auctioneer and surveyor from nearby Wraysbury, began livestock sales in a field near the Great Western Road Railway Station belonging to the North Star Inn. Originally held on the first Tuesday of every month, the Cattle Market's popularity soon saw this increased to every Tuesday. A move to Wexham Street was necessitated by the postwar redevelopment of the town. The Slough Cattle Market was run by Messrs Buckland and Sons until its final closure in 1988. In 1906, James Horlick, one of the founders of the eponymous malted milk company, opened a purpose-built red-brick factory near Slough Railway Station to manufacture his malted milk product. In 2015, the business was sold by Glaxo Smith Kline and in 2017, manufacturing at the site ceased altogether. The site is currently proposed to become residential making use of the original buildings as much as possible. Starting in the 1920s, Slough Estates Ltd, the operator of the original Slough Trading Estate, created and operated many more estates in the UK and abroad. The Slough Trading Estate meant that the town was largely insulated from many of the effects of recession. For many years, Slough's economy was mainly manufacturing-based. In the last 20 or so years, there has been a major shift from a manufacturing to an information-based economy, with the closure of many factories (some of which had been in Slough for many decades). The factories are rapidly being replaced by office buildings. Hundreds of major companies have sited in Slough Trading Estate over the years, with its proximity to London Heathrow Airport and good motorway connections being attractive. In the 1960s, Gerry Anderson's film company was
