On November 27, a little over two weeks before Washington's death, Dr. Craik delivered Nellie Custis, wife of Washington's nephew and private secretary, Lawrence Lewis, of a daughter, her first child.

December 12, 1799, was a bad day. General Washington, making the usual rounds of his farms, was not deterred by snow, sleet, nor the cold rain that followed. Coming in late to dinner, which was awaiting him, his clothes soaked, snow clinging to his hair, he did not take time to change his wet things. The next day he had a sore throat and was very hoarse. During the night he felt ill and awoke his wife. As soon as it was daylight, Mrs. Washington sent a messenger posthaste for Dr. Craik. Before he arrived, Washington insisted upon being bled, and his secretary, Tobias Lear, sent across the river to Port Tobacco for Dr. Gustavus Brown. When Dr. Craik arrived he was alarmed at the condition of his friend, bled him twice, and asked to have Dr. Dick called for consultation. The three doctors battled with their primitive knowledge as best they knew how. Dr. Craik rarely left the room, sitting by the fire, his hand cupped over his eyes. Mrs. Washington sat at the foot of the bed, while Tobias Lear noted every passing moment for posterity and gave what aid he could to make the patient comfortable. About five o'clock Washington said to Craik, "Doctor, I die hard but I am not afraid to go. I believed from my first attack that I should not survive it. My breath cannot last long." Life dragged five hours more, and when the end came Dr. Craik closed the eyes of him who was his best friend.[156] The watch which ticked off these awful moments is preserved in the Museum at Mount Vernon. When the General's will was opened one of the clauses read:

To my compatriot in arms, and old & intimate friend, Doctr Craik, I give my Bureau (or as the Cabinet makers call it, Tambour Secretary) and the circular chair—an appendage of my Study.[157]

Mantel in the house at 209 Prince Street which John Harper rented to Dr. Craik from 1790 to 1795 at £60 per annum and which bears a plate erroneously marking the domicile of Dr. Dick, who lived next door

This desk and chair migrated with a later generation of Craiks to Kentucky and afterward the heirloom chair was presented as a token of esteem to General Andrew Jackson. Happy to relate, both pieces are again united in the library at Mount Vernon.

There remained for Dr. Craik one more duty to perform at Mount Vernon. In May 1802, two and a half years after the death of her husband, Martha Washington fell ill. This old friend of her married life of forty years watched over her for the seventeen days that remained and was with her, too, when she breathed her last.

Doctor Craik lived for fifteen years after the death of his friend and patron, hale and hearty to the end. In 1810 he put up his Alexandria house as security for a loan and it was sold at public auction March 23, 1810, to Rebecca Taylor.

Doctor Craik died on February 6, 1814, in his eighty-fourth year at his country estate, Vauclause, near Alexandria. He lies in the graveyard of the old Presbyterian meetinghouse.

His house in Alexandria, at 210 Duke Street, was fittingly enough in 1943 made habitable once again by another physician, Dr. Laurence A. Thompson, and Mrs. Thompson.
