PARIS — Henry Rousso is one of France’s most preeminent scholars and public intellectuals. Last week, as the historian attempted to enter the United States to attend an academic symposium, he was detained for more than 10 hours — for no clear reason.

On Wednesday, Rousso arrived at Houston’s George Bush Intercontinental Airport after an 11-hour flight from Paris, en route to Texas A&M University in College Station. There, he was to speak Friday afternoon at the Hagler Institute for Advanced Study.

But things did not go according to plan: Rousso — an Egyptian-born French citizen — was “mistakenly detained” by U.S. immigration authorities, according to Richard Golsan, director of the Glasscock Center for Humanities Research at Texas A&M.
