David Lamar (circa 1877 - January 12, 1934) was a con man known as the "Wolf of Wall Street".
During 1915, Lamar acted as an agent for Franz von Rintelen, an agent for the German Navy intelligence in New York City. He promoted strikes and work slowdowns in munitions plants by means of the Labor's National Peace Council. From offices at 55 Liberty Street, von Rintelen spent US$500,000, most of which went to Lamar, whose reports of success were exaggerated.
Lamar died in 1934.
- Hearings. United States Congress. 1913. "Very well; I desire to testify now, then, that two years ago, when I first used the name of Riordan, I told the man I used it with at the end of, say, three conversations, that were all within a period of two days, that I was David Lamar. That man was Mr. Charles Steele. Mr. Ledyard has testified here, and the committee will see it—I can call their attention to it—Mr. Ledyard says he knew of these conversations between Mr. Riordan and Mr. Steele. So that two years ago, if my testimony is to be believed, Steele knew it was not David Lamar he was talking with but that it was Riordan"
