Elijah Bond was best known for filing the first United States patent for the Ouija board. Born in Harford County, MD in 1847, Bond became a successful lawyer in Baltimore City, starting his own practice in the 1870s. He filed the Ouija patent on behalf of the Kennard Novelty Company in 1891. Elijah Bond died in 1921 and was anonymously buried in his family’s plot at Green Mount Cemetery. Robert Murch, America’s foremost Ouija historian, after fifteen years of searching, located the ambiguous grave. Murch erected the Ouija-themed headstone in 2008. The cemetery’s mausoleum is nearby.
