ALFRED TARSKI - LIFE AND LOGIC

Alfred Tarski, one of the greatest logicians of all time, is widely thought of as 'the man who defined truth'. His mathematical work on the concepts of truth and logical consequence are cornerstones of modern logic, influencing developments in philosophy, linguistics and computer science. Tarski was a charismatic teacher and zealous promoter of his view of logic as the foundation of all rational thought, as well as a bon-vivant and a womanizer, who played the 'great man' to the hilt. Born in Warsaw in 1901 to Jewish parents, he changed his name and converted to Catholicism, but was never able to obtain a professorship in his home country. A fortuitous trip to the United States at the outbreak of World War 1 saved his life and turned his career around, even though it separated him from his family for years. By the war's end, Tarski was established as a professor of mathematics at the University of California, Berkeley, where he started a department in logic and methodology that attracted students and distinguished researchers from all over the world. From the cafes of Warsaw and Vienna to the mountains and deserts of California, this first full- length biography places Tarski in the social, intellectual and historical context of his times. It presents a vivid picture of a personally and professionally passionate man, interlaced with an account of his major scientific achievements. Anita Burdman Feferman is an author and biographer who has written on noted figures such as Jean van Heijenoort and Georg Kreisel. Solomon Feferman is a professor of Mathematics and Philosophy at Stanford University. Both authors were closely acquainted with Tarski and in a unique position to write about his life.
