Olmsted and Bove were chosen from a "very talented pool" of nine applicants, Krebs said. The positions were open to all seniors.

"They explained why they wanted to be involved in the class for the rest of their lives," Krebs said. "They were very enthusiastic, and their enthusiasm was contagious."
Olmsted said she applied because she wanted to help the senior class maintain ties to each other and Harvard.
"I really want everyone to keep in touch and not forget about the four years they had here," she said.
Bove, who is a Crimson executive, could not be reached for comment.
