For those of us in the capital, some of the Heritage Open Day sites are much closer than you might expect (57 are within the M25). IanVisits has an excellent list of highlights in the south-east, including the Horlicks factory. As a taster for their tour (pre-booking required), here's a look back at my visit in 2010.
No night starvation in Slough
Slough, west of London, isn't really thought of as a heritage hotspot. Its reputation was hardly helped by the Betjeman poem which begins, 'Come friendly bombs and fall on Slough!' However, the
Horlicks has something of an Anglo-American heritage, although its biggest market today is India. The drink was first produced in the USA by two English brothers, William and James Horlick, in 1873. By the 1890s James had established an office in London, and the Slough factory was opened in 1908.
Initially the drink was targeted at infants (it's no longer recommended as a baby food), but by the early twentieth century it had found a new market. Compact, nutritious, and made using only water rather than hot milk, it was popular with arctic and antarctic explorers. However, its 1930s advertising campaign really shaped perceptions of the drink: promising to stave off 'night starvation', it firmly associated Horlicks with a good night's sleep.
Both boardroom and archives are treasure troves of old products and packaging, as well as photographs and other memorabilia. Among the most evocative were the staff magazines.
