A Celebration of Life service for Alexander Capelluto ’07 will be held Sept. 10 in Battell Chapel, Yale College Dean Peter Salovey said in an e-mail sent to all Yale undergraduates on Tuesday.

Nearly four months ago, the 20-year-old Capelluto was struck and killed by a 10-wheel truck at the intersection of Derby Avenue and Forest Road in West Haven while biking to campus from the Gilder Boathouse. According to the West Haven Police Department, no one has been charged in the incident, but the accident is still under investigation.

Capelluto was described by those who knew him as a fun-loving and outgoing instructor, student and friend — an energetic young man whose dedication and zeal spilled over into those around him, whether he was organizing Hurricane Katrina relief efforts, participating in FOOT or gearing up for the Habitat for Humanity bike challenge.

“He ‘got’ everyone he met; he understood them and helped them understand each other,” Capelluto’s sister, Katherine Capelluto ’04, said in an e-mail. “Losing Alexander leaves a hole in all our lives.”

The memorial service will begin at 2:30 p.m., with a reception to follow in the Berkeley Common Room.
