Dr. Edward Livingston Trudeau at work in the Saranac Laboratory, c. 1895. According to Marguerite Armstrong, superintendent of the Adirondack Cottage Sanitarium and friend of Dr. Trudeau, this is the “best picture ever taken” of him. Visitors to the Saranac Laboratory Museum can see Dr. Trudeau’s office as part of their visit! (Provided photo — Historic Saranac Lake Collection, TCR 682. Courtesy of Trudeau Institute)
