Sanford Quest

Origin
Sanford Quest - A criminologist and scientific detective who uses a wide variety of gadgets of his own invention, including an “electric mind-reader," a viewphone, a pocket bomb made of a super-powerful explosive, and a "pocket wireless telephone," to fight against crime. He was also an expert in hypnosis.  He was athletic, an exceptional fighter and extremely brave and level headed.  He is described by one characters as, "the greatest master in criminology the world has ever known. He is a magician, a scientist, the Pierpont Morgan of his profession.”

Quest investigated the mystery of the black box and brought down Lord Professor Ashleigh, a mad scietist who has created a suit which renders the wearer invisible when charged with electricity. Ashleigh’s reign of terror was brought to an end when he was killed in a fight to the death with Quest.
