Periscope Inventor Dead.
Atlantic City, N.J., March 24. - Morgan Robertson, one of the best-known
short story writers, and the inventor of the periscope, used on all
submarines, was found dead in his room at the Alamac Hotel this afternoon.
Physicians say he died from an overdose of protiodide.  Mr. Robertson was
sixty-five years old.  His body will be brought to this city tomorrow.
The periscope was first conceived by Mr. Robertson in his book "The
Submarine Destroyer".  When the story was first published in 1905 officials
of the Holland Submarine Co. sent for the author and asked him if he
considered the scheme practical.  "Of course I do," he replied.  "Here is
a model of it which I have already patented."  Officials of the company
were so impressed that they purchased the invention for $50,000.  A
financial appeal on behalf of Mr. Robertson was recently made through
American magazines.
