B.A. Santamaria was one of the most controversial Australians of our time. An ardent anti-Communist and devout Catholic, he was fiercely intelligent and a natural leader, polarising the community into loyal followers and committed opponents. In the 1940s Santamaria created the anti-Communist organisation 'The Movement'. In the 1950s he was a key figure in the tumultuous split of the Australian Labor Party. He subsequently enjoyed great influence as a public commentator on his television program Point of View and in his weekly column in The Australian . Santamaria had a strong social conscience and spent much of his time helping the underprivileged. Although he began as an advocate and champion of the Catholic Church, he spent much of his last decades opposing some of its activities. Published for the 100th anniversary of Santamaria's birth, Santamaria: A Most Unusual Man is an authoritative biography from Gerard Henderson, a close colleague until a disagreement saw the two men estranged and never reconciled.
