Edward R. “Ted” Hennessy Jr. ’88, a passenger on American Airlines flight 11, died when his plane crashed into the World Trade Center in Tuesday’s terrorist attack. He was 35.

Hennessy, a native of Belmont, was a consultant for Emergence Consulting and heading to Los Angeles on a business trip.

A resident of Leverett House while an undergraduate, Hennessy graduated from the College cum laude as a biology concentrator.

While a student at Harvard, Hennessy was very involved in the Hasty Pudding Theatrical Club. He played in the orchestra of the Pudding show during each of his four years at the College. He was also a co-writer of the Pudding’s 1989 show “Whiskey Business.”

Those who knew him from the Pudding describe him as a very active member of the club who spent a great deal of time at the club’s Holyoke Street theater.

However, they said even as he spent hour upon hour at the Pudding, he always managed to have fun and enjoy life.

“He was a happy-go-lucky, fun-loving guy,” said Ronald E. Corcillo ’89, who was Hennessy’s partner in writing “Whiskey Business.”

“He was the kind of guy you always wanted to hang out with,” said Cori Fisher McRae ’88, who also played in the Pudding’s orchestra. “He was truly one of the best people I’ve ever known.”
