But right now, as the face of his country's effort to find Malaysia Airlines Flight 370, he is the man who has delivered more than two weeks of frustrating news about one of the most confounding searches in aviation history.
The bespectacled 52-year-old defense minister has come under fire for just about everything that's gone wrong with the unprecedented hunt from delayed radar tracking data to confusion over when police searched the homes of the missing plane's pilots.
His handling of the search could affect not only his own future but that of Malaysia's ruling party, which has been struggling to stay in power after six decades in charge.
The tech-savvy minister, who tweets regularly and has a Twitter following in excess of 600,000, tried to overcome some of that criticism Saturday when he read out a handwritten note passed to him at the end of a press briefing that bore the latest clue: A Chinese satellite had spotted debris that might belong to the jetliner.
Hishammuddin's family connections go even farther than that. His grandfather, Onn bin Ja'afar, founded the ethnic Malay party that has dominated politics here ever since Malaysia gained independence from Britain in 1957.
