I. F. Stone has been a journalist since 1922, when at the age of fourteen he launched a monthly, The Progress, supporting such causes as Gandhi's moves for freedom in India, and the League of Nations. After studying philosophy at the University of Pennsylvania, he worked on various newspapers in New Jersey, Philadelphia and New York, including The Nation and the New York Post. He is best known for his notoriously radical one-man Washington news-sheet, I. F. Stone's Weekly, which he ran for nineteen years before he was forced to close it just before Watergate, due to ill health.

One of Izzy Stone's favourites among many scoops was his discovery that underground nuclear tests could be detected thousands of miles away and not, as Eisenhower's administration held, simply within a radius of 200 miles. For many years he was denied a White House press card and was still being falsely branded recently be one British political weekly as a Marxist. "You shouldn't really have a party affiliation as a journalist," Stone (an admirer of Kipling) told an interviewer in the New Statesman in 1986, "but at the same time a journalist should do whatever his conscience tells him he should."

Always a campaigner for civil liberties, he had no intention of settling into docile domesticity after the demise of I. F. Stone's Weekly. Instead he acquired a computer with letters one third of an inch high, with which to overcome failing sight caused by cataracts, and embarked on a history of free speech. He was seventy (the same age as Socrates when he was brought to trial) before he decided to teach himself classical Greek. It took ten years to complete The Trial of Socrates

Stone is the author of eleven earlier books, including In a Time of Torment and The Killings at Kent State. He has lectured at many universities, including Oxford, Harvard and Yale, and has received awards from Princeton and McGill Universities for his forays into Athenian thought and politics.
