“I can tell you right now that I don’t have a definitive answer as to who the high bidder is or what the intended use will be,” said Margie Philo, who is managing the auction as the real estate broker for Adirondack Premiere Properties, associated with Berkshire Hathaway Home Services. Press was not allowed inside during the course of the auction, but Philo said at its conclusion around 1 p.m. that there are five interested parties.

She said she couldn’t reveal names, but she did say that only one of the people had bought property in the Adirondacks before.

Similarly, Philo said she couldn’t reveal any of the current bids. Through the combination of in-person and online auctioning, they had yet to resolve a highest bidder.

“There’s a lot of activity,” Philo said.

The auction saw the possible sale of more than 63 acres and 27 structures. More than half of the structures on site were built before 1915. As such, the majority of the buildings on campus are minimally heated, and four structures have no electricity or heating systems.

Construction at the campus began in 1884 as the Adirondack Cottage Sanitarium, a tuberculosis treatment facility under the direction of Dr. Edward Livingston Trudeau. (Correction: An earlier version of this article had the facility’s original name wrong.) It was later renamed Trudeau Sanatorium and closed in the 1950s after a drug to cure tuberculosis was made available the decade before. AMA bought the property in 1957.

Until 1971, AMA used the site as a conference center. It is now used as an operations support center and a call center. AMA still occupies two of the buildings on site and is moving out of a third. According to its website, AMA employs 180 people on the campus.
