The smell of cocoa was unforgettable for Queenstown residents living in Tanglin Halt during the 60s and the 70s. Chocolate making factories such as Sheng Huo and Van Houten were two of the 38 factories that lined up Tanglin Halt Road. These factories were located conveniently for women so that they could join the workforce and support the industrialisation project in the 1960s. Tanglin Halt is also home to South East Asia's first assembly line producing television sets. Setron, which was opened in 1964, rolled out the first black and white television sets. It had a very special roof top that shaped like an inverted pyramid which navigated drivers into Tanglin Halt district. All of these would not be possible without one man-Dr Goh Keng Swee.
