The historian Bernard Lewis celebrated his 100^th birthday on Tuesday.

Three quotes establish his career. Martin Kramer, a former student of Lewis, sums up his teacher’s accomplishments:

Bernard Lewis emerged as the most influential postwar historian of Islam and the Middle East. His elegant syntheses made Islamic history accessible to a broad public in Europe and America. In his more specialized studies, he pioneered social and economic history and the use of the vast Ottoman archives. His work on the premodern Muslim world conveyed both its splendid richness and its smug self-satisfaction. His studies in modern history rendered intelligible the inner dialogues of Muslim peoples in their encounter with the values and power of the West.

The University of California’s R. Stephen Humphreys notes “the extraordinary range of his scholarship [and] his capacity to command the totality of Islamic and Middle Eastern history from Muhammad down to the present day.” And, as the late Fouad Ajami of Johns Hopkins University put it on Lewis’ 90^th birthday, he is “the oracle of this new age of the Americans in the lands of the Arab and Islamic worlds.”

Lewis’ career spanned a monumental 75 years, from his first article (“The Islamic Guilds“) in 1937 to his autobiography in 2012. Midway, in 1969, he entered my life. In Israel the summer between my sophomore and junior years in college, with my aspirations to become a mathematician in doubt, I thought of switching to Middle East studies. To sample this new field, I visited Ludwig Mayer’s renowned bookstore in Jerusalem and purchased The Arabs in History, Lewis’ 1950 book.

It launched my career. Over the next 47 years, Lewis continued to exert a profound influence on my studies. Although never his formal student, I absorbed his views, reading nearly all his writings and favorably reviewing seven of his books (in 1982, 1986, 1988, 1989, 1994, 1996 and 2000), far more than those of any other author. His name appears on 508 pages of my website. Beyond numbers, he more than any one else influenced my understanding of the Middle East and Islam.

That said, he and I argued strenuously during the George W. Bush years, narrowly on Iraq policy (I was more skeptical of U.S. efforts) and broadly on the matter of bringing freedom to the Middle East (ditto).

I first met Professor Lewis in 1973 in London, when he generously invited me to his house and offered advice on my Ph.D. studies. I saw him most recently, twice, at his small apartment in the Philadelphia suburbs.

He’s impressively fit in body and mind, spending time on the computer, ever the raconteur (“What’s a Jewish joke? One which non-Jews can’t understand and Jews have heard a better version of”), and conjuring up anecdotes from a time before the rest of us were born (his 1946 discussion with Abba Eban about the latter’s career choices). It’s wonderful to see him doing well even if it’s sadly understandable that he no longer engages in scholarship nor opines on current events.

Born a mere 15 days after the Sykes-Picot agreement that defined the modern Middle East, their common May centennial finds Syria and Iraq in shreds but more than ever is an inspiration to his many self-identified disciples, including this one.
