Marking Otto Maurer's grave

I am historian Tom Klem and I am raising money to mark the grave of magician and magic dealer Otto Maurer who died in 1900. He ran a magic shop on the Bowery for 28 years and taught Hermann, Houdini, T. Nelson Downs, Howard Thurston and many others magic in his wonderful shop. There is no marker for his grave in Queens, NY. All the money donated will go to the cost of the survey, footing and headstone. I will be paying the GoFundme costs. He deserved to be remembered. No amount is too small to give.  I would like to do this soon while the ground is soft and winter sets in. His grave will be marked and this man and magician will be honored. Thank you.
