Alexander Hesler

Using a portable darkroom, he also produced landscape scenes from nearby states and territories of what is now the American Midwest.

[1] Hesler's known portraits include photographs of the two chief Illinois political figures of his day, Lincoln and federal senator Stephen A. Douglas.

[1] Hesler's portable darkroom work included a widely circulated image of Minnehaha Falls, a waterfall located in what was to become the U.S. city of Minneapolis.
