The crowd booed. “I am not defensive,” he said.

According to people in attendance and a recording of the meeting obtained by The New York Times, one member accused Mr. Holland of sending misleading emails. People clapped when a person called for the club’s leadership to resign. Still others questioned why a change was necessary given the club’s overall financial health.

Depending on whom one talks to, the proposed change to Harvard Hall is either a vast conspiracy to turn the esteemed club into a catering-venue-for-hire or an attempt by the leadership to stem losses in its food and beverage business.

It is not uncommon in the genteel world of New York private clubs for members to weigh profit and convenience. But the members of the Harvard Club seem to be taking this proposal personally.

Ivan Shumkov, an architect, called it one of the most sacred spaces in New York, having been created by an architectural icon, the Harvard alumnus Charles McKim. “If we destroy Harvard Hall,” he said that night, “I think it will be the worst thing ever.”
