No Chinese residing in the International Settlement were permitted to join the council until 1928. Amongst the many members who served on the council, its chairman during the 1920s, Stirling Fessenden, is possibly the most notable. An American, he served as the settlement's main administrator during Shanghai's most turbulent era, and was considered more "British" than the council's British members. He oversaw many of the major incidents of the decade, including the May 30th Movement and the White Terror that came with the Shanghai massacre of 1927.
