Krauthammer was born to Jewish parents of French citizenship.[5] He was raised in Montreal, Canada where he attended McGill University and obtained an honors degree in political science and economics in 1970. From 1970 to 1971, he was a Commonwealth Scholar in politics at Balliol College, Oxford. He later moved to the United States, where he attended Harvard Medical School. In his first year there in 1972, Krauthammer was paralyzed in a serious diving accident. Continuing medical training during his year-long rehabilitation, he graduated with his class, earning a M.D. from Harvard Medical School in 1975, and then began working as a psychiatrist at Massachusetts General Hospital. In October 1984, he became board certified in psychiatry by the American Board of Psychiatry and Neurology.
From 1975-1978, Krauthammer was a Resident and then a Chief Resident in Psychiatry at the Massachusetts General Hospital. During this time he and a colleague identified a form of mania (a part of bipolar disorder) which they named “secondary mania”[6] and published a second important paper.[7] The standard textbook for bipolar disease (“Manic Depressive Illness” by Goodwin and Jamison) contains nine citations of his work.
In 1978, Krauthammer quit medical practice to direct planning in psychiatric research for the Jimmy Carter administration, and began contributing to The New Republic magazine. During the presidential campaign of 1980, Krauthammer served as a speech writer to Vice President Walter Mondale.
In 1981, following the defeat of the Carter/Mondale ticket, Krauthammer began his journalistic career, joining The New Republic as a writer and editor. His New Republic writings won the 1984 “National Magazine Award for Essays and Criticism.” In 1983, he began writing essays for Time magazine. In 1985, he began a weekly column for the Washington Post for which he won the 1987 Pulitzer Prize for commentary.
In 2006, the Financial Times named Krauthammer the most influential commentator in America,[8] saying “Krauthammer has influenced US foreign policy for more than two decades. He coined and developed `The Reagan Doctrine’ in 1985 and he defined the US role as sole superpower in his essay, `The Unipolar Moment’, published shortly after the fall of the Berlin Wall. Krauthammer’s 2004 speech `Democratic Realism’ set out a framework for tackling the post 9/11 world, focusing on the promotion of democracy in the Middle East.”
On the other hand, left-wing commentators have been quite hostile to Krauthammer. In a 2006 column in The American Prospect criticizing The New Republic and other proponents of democratization in Arab countries, Matthew Yglesias wrote that Krauthammer is “very possibly the worst journalist working in America today, a relentlessly pernicious force, never right about anything, who feels his commentary should not be shackled by the small-minded bonds of accuracy or logic.
