Apparently he was just having some trouble with the whole life/work balance.
After six weeks on the job, Lazard International chief executive officer Naguib Kheraj is stepping down, the firm announced today in an e-mailed statement.

"I am very sad to be leaving Lazard, and have not taken this decision lightly," said Kheraj in the statement. "I underestimated the difficulty of managing my external activities in a way that would enable me to be properly engaged in an executive role."
