Father Roberto Landell de Moura (January 21, 1861–June 30, 1928) was a Brazilian Roman Catholic priest and inventor who publicly demonstrated a radio broadcast of the human voice on June 3, 1900.
De Moura was ordained to the priesthood in 1886 in Rome. He also studied the physical sciences, and following his radio broadcast over 8 km in São Paulo, he was granted a Brazilian patent on March 9, 1901. De Moura then travelled to the United States and secured three patents there, for a "Wave Transmitter" (October 11, 1904), a "Wireless Telephone" and "Wireless Telegraph", both dated November 22, 1904. His subsequent requests to the Brazilian government for assistance in developing his invention were denied, and his efforts then languished.
