The Nathan B (Beverly) Stubblefield Wireless Telephone demonstration in Belmont Park, Philadelphia in 1902 was well attended by many of Stubblefield’s contemporary inventors and scholars, including Nikola Tesla.
An excerpt from documentary video “Nathan Stubblefield Speaks“
“As I look back I recall two lines from a poem, The Inventor and the Crank, written in 1886 by the man with the irony pin, yours truly Nathan Stubblefield.
Sad sad was the life of the old time wizard; his life must have been one continuous blizzard”
