Edward Livingston Trudeau (October 5, 1848 – November 15, 1915) was an American physician who established the Adirondack Cottage Sanitarium at Saranac Lake for the treatment of tuberculosis.

[3] Trudeau’s parents divorced shortly after he was born, and he traveled with his mom and brother to Paris, where they lived for a time before returning to New York City in 1865.

After returning to America, he began preparing for enlistment in the US Navy and attended the Naval Academy Preparatory School in Newport, Rhode Island.

In 1882, Trudeau read about Prussian Dr. Hermann Brehmer's success treating tuberculosis with the "rest cure" in cold, clear mountain air.

He died in May 1904 of an embolism after a bout of pneumonia and their daughter Alice was born on 10 October 1904 in Chicago, her mother's home town, later spending much of her life in Ireland.

Trudeau had many friends and was active in the community, helping to found St. John's in the Wilderness Episcopal Church in Paul Smiths, New York, where he is interred.

The plaque honors a historic experiment of Trudeau's in which rabbits were injected with tuberculosis "to determine the effect of environment on the influence and progress" of the disease.
