Eleazer was one of the many dentists in Stephen's branch of the family -- there were 13 of them in two generations.

He was schooled in Montreal, was a reporter for the Canadian Courant during the War of 1812, lived in London and then returned to the United States in 1821, settling in New York City where he practiced at 297 1/2 Broadway.at the corner of Duane Street.

In November, 1826, he stopped in at the White House to introduce himself to John Quincy Adams and extracted some of the president's bad teeth. You can read JQA's diary entries for those dates.
