Argument over land This dour man is nonetheless remembered for at least one example of his wit. In his memoir, recounting his failure in 1853 to reach agreement with David Swinson "Doc" Maynard over what was intended to be a joint plat of the town of Seattle, he wrote, "it was found that the doctor, who occasionally stimulated a little, had that day taken enough to cause him to feel that he was not only monarch of all he surveyed, but what Boren and I had surveyed as well."
It was later shown in a review done by a professional engineering firm on behalf of the city that it was in fact Denny that was wrong about the direction the streets should run and had actually violated the law in his plat of the city.
