This week marks the fourth annual UA Conference on the Holocaust, a series of events geared to educate the campus community about the millions of people killed during the Holocaust and the few who survived.

Organizers handed out origami butterflies attached to black ribbons on the UA Mall yesterday, while names of Holocaust victims were read aloud.

The butterflies, crafted by the UA Conference on the Holocaust committee, symbolize life or hope, and the ribbons, donated by Evergreen Mortuary, symbolize the death of the millions of people killed, said Jason Kaufman, co-chair of the committee and business and public administration senior.

More than 20,000 names will be read during the 25-hour vigil that ends today at 1 p.m. University of Arizona students and community members provided the names of family members and friends for the vigil.

Arash Feyzjou, business management and marketing senior, said he felt students were too "happy-go-lucky" and needed to be brought "back into reality" through the vigil.

"Just think that six million people were killed," he said.

Other members of the committee agreed the campus needed to be enlightened about the Holocaust.

"It's important to have this out in the public like this," said Michael Jeser, committee member and psychology sophomore. "Otherwise the only people who know about it will be the ones who already know."

Committee co-chair Alisha Eisenstock said, "This is what happened. Let's come together and remember and not let it happen again."
