In 1900, together with Ho Fook, Lau Chu-Pak founded the Chinese General Chamber of Commerce, of which he later became Chairman. He was one of Hong Kong's chief philanthropists of the early 20th century.
According to Wikipedia, Lau held various public posts such as the chairman of the Po Leung Kuk and Tung Wah Hospital, member of the District Watch Committee and the Sanitary Board. He was appointed an Unofficial Member of the Legislative Council from 1913 until 1922. He helped to found the University of Hong Kong by donating to the endowment fund in 1911. He later became the member of the University's Court between 1911 and 1914 and was made a Life Member of the Court in 1914. He was a member of the University Council from 1911 until his death in 1922. Together with his fellow Legislative Councillor, Ho Fook and with the support of other Chinese community leaders, he established the Society for the Protection of the Mui Tsai. I'm sure others will wish to add to this list of Lau's posts and philanthropic gestures.
An earlier Gwulo thread finds Lau Chu-Pak living at Ardmore, 1 Babington Path in 1908. The 1918-19 Rate Book gives him as the owner of 12 Broadwood Road. After his death this house became the property of Lau Fung Shi.
