Herman Daniel Umbstaetter (February 26, 1851 – November 25, 1913) was an American businessman and founder of the magazine The Black Cat.
[3] He worked in the United Kingdom for a while, but lost his fortune and returned to the US, spending some time in California before settling in Boston in 1891.
[3][4] He began to have health problems in 1912, and that year he sold The Black Cat to Samuel Cassino, the publisher of Little Folks.
[7] On November 25, 1913, Umbstaetter and Howard Palmer went on a hunting expedition on the shore of Kezar Lake in the Maine woods.
Umbstaetter stumbled as he tried to cross a stone wall and fell, resulting in his rifle accidentally discharging and a bullet passing through the left side of his body.
