Question: At what age did the person who Stevens worked under in 1929 die? Passage:Stevens grew up in Sydney and was an accountant and public servant before entering politics. He was elected to the New South Wales Legislative Assembly at the 1927 state election, as a member of the Nationalist Party. In 1929, he was appointed state treasurer under Thomas Bavin, serving until his party lost the 1930 election. In 1932, Stevens was elected as the inaugural leader of the state branch of the UAP. He became premier later that year, following the dismissal of Labor's Jack Lang, and subsequently led his party to victory at the 1932, 1935, and 1938 elections. Stevens was ousted in 1939 and replaced by Alexander Mair. He made an abortive attempt to enter federal politics at the 1940 election, and thereafter played little part in public life.
