Marian H. Smith ’04, a product of an upbringing that spanned continents who drew unlikely personalities together through her warmth, vibrancy and love of different cultures, died in an apparent suicide Friday. She was 19.

The official cause of death has not yet been determined.

Born in Kenya but raised in Somalia and Luxembourg, the Winthrop House resident spoke six languages and was learning a seventh. Her desire to develop a greater understanding of humanity led her to study social anthropology.

She kept up a packed calendar of engagements, often scheduling lunch dates on the fly as she walked to the Yard. Her frequent trips exploring Boston took her to many restaurants and clubs.

Recognized for her sense of style, Smith looked equally at home in high fashion and in finds from the Salvation Army. Friends often complimented her on the Hanes t-shirts she decorated with feathers in her dorm room.

Thought to be the unifying force in her blocking group, Smith brought an intense personality to her many friendships and a charm that made people feel special in her company.

“Everyone who knew her felt like she was one of their closest friends,” said one of her friends. And “everyone knew her.”

Cell phones messages to Smith’s friends were constantly interrupted by her stopping to talk with acquaintances who happened to be passing by.

Even at clubs in Boston, she carried on serious conversations with people she had just met.

“A conversation with Marian was never a surface conversation,” said Deanna E. Barkett ’03.

Friends said men were frequently drawn to Smith’s “bubbly” personality, but that she was too humble to realize how many admirers she had.

Seven of Smith’s closest friends, who met to speak about her yesterday, said Smith could turn strangers into best friends. They asked that their names not be used because they wanted to make clear the scope of Smith’s impact on those she knew without drawing attention to a single person’s grief.

“She wasn’t like any of the students here at all,” one friend said. “And yet she got along with everyone.”

Peter J. Giordano ’04, a friend since the two were first-years, said when he and Smith lived across the hall last year, they spent hours “just crashing at each others’ rooms, hanging out and laughing.”

“She was just a really, really outgoing and fun, friendly person,” Giordano said.
