The Hon. Sidney Waterson, born 1896 in England, came to South Africa and served with the South African Forces in World War I. He became a Member of Parliament for the South Peninsula in 1929, was High Commissioner for the London Union from 1938, and was a Member of Parliament for Claremont from 1943 to 1953 and for Constantia until 1970. In 1935, he bought a home on the corner of Moselle Rd and Westray Steps in St James.

He married Hilda – known as ‘Betty’ – in 1924. She was a nurse with the Anglo-French Red Cross and helped establish the First RC Voluntary Aid Detachment No.122 in 1936. At the outbreak of war in 1939 she was active in the South Peninsula and founded the SA Voluntary Service to the Armed Forces and to channel gifts from SA to Britain. In later years they moved to Kenilworth, where Waterson died aged 80 and Betty four years later.
