input: By 1874, Bell's initial work on the harmonic telegraph had entered a formative stage, with progress made both at his new Boston "laboratory" (a rented facility) and at his family home in Canada a big success. While working that summer in Brantford, Bell experimented with a "phonautograph", a pen-like machine that could draw shapes of sound waves on smoked glass by tracing their vibrations. Bell thought it might be possible to generate undulating electrical currents that corresponded to sound waves. Bell also thought that multiple metal reeds tuned to different frequencies like a harp would be able to convert the undulating currents back into sound. But he had no working model to demonstrate the feasibility of these ideas.  In 1874, telegraph message traffic was rapidly expanding and in the words of Western Union President William Orton, had become "the nervous system of commerce". Orton had contracted with inventors Thomas Edison and Elisha Gray to find a way to send multiple telegraph messages on each telegraph line to avoid the great cost of constructing new lines. When Bell mentioned to Gardiner Hubbard and Thomas Sanders that he was working on a method of sending multiple tones on a telegraph wire using a multi-reed device, the two wealthy patrons began to financially support Bell's experiments. Patent matters would be handled by Hubbard's patent attorney, Anthony Pollok.  In March 1875, Bell and Pollok visited the scientist Joseph Henry, who was then director of the Smithsonian Institution, and asked Henry's advice on the electrical multi-reed apparatus that Bell hoped would transmit the human voice by telegraph. Henry replied that Bell had "the germ of a great invention". When Bell said that he did not have the necessary knowledge, Henry replied, "Get it!" That declaration greatly encouraged Bell to keep trying, even though he did not have the equipment needed to continue his experiments, nor the ability to create a working model of his ideas. However, a chance meeting in 1874 between Bell and Thomas A. Watson, an experienced electrical designer and mechanic at the electrical machine shop of Charles Williams, changed all that.  With financial support from Sanders and Hubbard, Bell hired Thomas Watson as his assistant, and the two of them experimented with acoustic telegraphy. On June 2, 1875, Watson accidentally plucked one of the reeds and Bell, at the receiving end of the wire, heard the overtones of the reed; overtones that would be necessary for transmitting speech. That demonstrated to Bell that only one reed or armature was necessary, not multiple reeds. This led to the "gallows" sound-powered telephone, which could transmit indistinct, voice-like sounds, but not clear speech.

input: In 1994 the character was adapted once again into a feature film, The Shadow, starring Alec Baldwin as Lamont Cranston and Penelope Ann Miller as Margo Lane. As the film opens, Cranston has become the evil and corrupt Yin-Ko (literally "Dark Eagle"), a brutal warlord and opium smuggler in early 1930s Mongolia. Yin-Ko is kidnapped by agents of the mysterious Tulku, who begins to reform the warlord using the psychic power of his evolved mind to restore Cranston's humanity. The Tulku also teaches him the ability to "cloud men's minds" using psychic power in order to fight evil in the world. Cranston eventually returns to his native New York City and takes up the guise of the mysterious crime fighter "The Shadow", in payment to humanity for his past evil misdeeds: "Who knows what evil lurks in the hearts of men? The Shadow knows..."  His nemesis in the film is adapted from the pulp series' long-running Asian villain (and for the film, a fellow telepath), the evil Shiwan Khan (John Lone), a descendant of Genghis Khan. He seeks to finish his ancestor's legacy of conquering the world by first destroying New York City, using a newly developed atomic bomb, in a show of his power. Khan nearly succeeds in this, but he is thwarted by The Shadow in a final psychic duel of death: Cranston, as The Shadow, imposes his will on, and defeats, Khan during a psychokinetically enhanced battle in a mirrored room, which has exploded into thousands of flying mirror shards. Focusing his mind's psychokinetic power, The Shadow flips a flying piece of jagged mirror in mid-air and then hurls it directly at a spot on Khan's forehead; this does not kill him, it renders him unconscious. To save both the warlord and the world, The Shadow secretly arranges with one of his agents, an administrative doctor at an unidentified New York asylum for the criminally insane, to have Khan locked away permanently in a padded cell; Khan's badly-injured frontal lobe, which controlled his psychic powers, having been surgically removed.  The film combines elements from The Shadow pulp novels and comic books with the aforementioned ability to cloud minds described only on the radio show. In the film Alec Baldwin, as The Shadow, wears a red-lined black cloak and a long red scarf that covers his mouth and chin; he also wears a black, double-breasted trench coat and a wide-brimmed, black slouch hat; as in the pulp novels, he is armed with a pair of Browning .45-caliber semi-automatic pistols that for the film have longer barrels, are nickel-plated, and have ivory handles. The film also displays a first: Cranston's ability to conjure a false face whenever he is in his guise as The Shadow, in keeping with his physical portrayal in the pulps and the comics.  The film was financially and critically unsuccessful.
