CHICAGO, Sept. 27.—Attorney Lawrence J. J. Nissen was found lying dead in his office at 170 East Madison street yesterday morning. Upon a table near by stood an empty morphine bottle. At his late home, 107 Schiller street, whither the body was at once conveyed, the theory of suicide is discredited, and the confidence expressed that he died of paralysis. The deceased was for forty years a resident of Chicago, and was formerly a partner of Judge Barnum in the law business. He was fifty-nine years of age and leaves a wife and several grown children.

So I was going to put this in the “Suicide” category, but then I did additional research and found this article that made me change it to the “Accidental Death” category:

They Sought Relief from Insomnia.

An inquest was held yesterday at No. 432 West Twelfth street on the body of the lawyer, Lawrence J. J. Nissen, who was found dead in his office, No. 170 East Madison street, Sunday morning. A partly emptied bottle labeled morphine was found on a table by the side of the dead man. From the testimony of the daughter, Miss Emma Nissen, a teacher of elocution, it was learned that the lawyer had for years past suffered from insomnia, and that he was always in the habit of taking the drug to induce sleep. Some five years ago he had a narrow escape from death by taking an overdose. Judge Barnum, a former law partner of deceased, also stated that Mr. Nissen was long a sufferer from sleeplessness. The verdict was in accordance with the facts.
