Alternatively, "ang moh" may refer to John Turnbull Thomson, a British civil engineer and artist who played an instrumental role in the development of the early infrastructure of late 19th century Singapore and New Zealand. Thomson, who had distinctive red-coloured hair, was responsible for building a bridge during the colonial days of Singapore, to facilitate logistic transportation to the nearby British military bases at Seletar until the British military withdrawal in the 1970s. The bridge no longer exists, but according to local historians, was previously located at the junction of Ang Mo Kio Avenue 1 and Upper Thomson Road.
