Havel's plays were banned as hard-liners installed by Moscow snuffed out every whiff of rebellion. But he continued to write, producing a series of underground essays that stand with the work of Soviet dissident Andrei Sakharov as the most incisive and eloquent analyses of what communism did to society and the individual.
One of his best-known essays, "The Power and the Powerless" written in 1978, borrowed slyly from the immortal opening line of the mid-19th century Communist Manifesto, writing: "A specter is haunting eastern Europe: the specter of what in the West is called 'dissent.'"
In the essay, he dissected what he called the "dictatorship of ritual" — the ossified Soviet bloc system under Leonid Brezhnev — and imagined what happens when an ordinary greengrocer stops displaying communist slogans and begins "living in truth," rediscovering "his suppressed identity and dignity."
Havel knew that suppression firsthand.
Born Oct. 5, 1936, in Prague, the child of a wealthy family which lost extensive property to communist nationalization in 1948, Havel was denied a formal education, eventually earning a degree at night school and starting out in theater as a stagehand.
His political activism began in earnest in January 1977, when he co-authored the human rights manifesto Charter 77, and the cause drew widening attention in the West.
Havel was detained countless times and spent four years in communist jails. His letters from prison to his wife became one of his best-known works. "Letters to Olga" blended deep philosophy with a stream of stern advice to the spouse he saw as his mentor and best friend, and who tolerated his reputed philandering and other foibles.
