Mr. and Mrs. Louis Duennisch


Louis Duennisch was born in Saxony, Germany on September 4, 1842. In 1857 he and his widowed mother emigrated to the United States, settling in Sandusky, Ohio. For thirty five years, he was employed by the Sandusky Sash, Door & Blind Company, and its successors. Mr. Duennisch was made foreman of the shop when he was only nineteen years old. 

On July 2, 1867, Louis Duennisch took Margaret Newman as his bride; she passed away in 1875. He married Margaret Ebert in 1878, the daughter of Conrad Ebert, a native of Bavaria.. 


Between 1895 and the early 1900s, the couple traveled extensively in the United States and Europe. Descendants of the Duennisch and Ebert families bequeathed a photograph album to the Sandusky Library Research Center, which contains many pictures from their travels.  Below is a picture of Mr. and Mrs. Duennisch in Madeira (part of Portugal, despite the caption).


For many years, Mr. Duennisch served as a trustee of Oakland Cemetery. The front page of the Sandusky Sunday Register of October 10, 1886 featured a story which reported on an electrical device which he had invented. Having heard of cases of “suspended animation,” in which a living person had been buried alive, Louis wanted to provide an escape method for an individual finding oneself in this unfortunate situation.  Insulated rings were to be attached to the body in the coffin, and these were wired to an alarm bell in the bedroom of the cemetery superintendent. At the slightest movement of an individual’s fingers, an alarm would ring loudly in the superintendent’s room. We do not know if this invention was actually implemented by Oakland Cemetery, but on October 10, 1888, it was lauded as “one of the grandest triumphs of electrical science.” 

Louis Duennisch died on October 4, 1918. He was buried in the North Ridge section of Oakland Cemetery.
