Elisha ( /ɨˈlaɪʃə/;Hebrew: אֱלִישָׁע, Modern Elisha Tiberian ʼĔlîšāʻ ; "My God is salvation", Greek: Ἐλισσαῖος, Elissaîos or Ἐλισαιέ, Elisaié, Arabic: الْيَسَع‎ Elyasaʻ) is a prophet mentioned in the Hebrew Bible and the Qur'an. His name is commonly transliterated into English as Elisha via Hebrew, Eliseus via Greek and Latin, or Alyasa via Arabic.

Elisha was a prophet of the Northern Kingdom of Israel who was active during the reign of Joram, Jehu, Jehoahaz, and Jehoash (Joash).

Elisha was the son of Shaphat of Abel-meholah; he became the attendant and disciple of Elijah (1 Kings 19:16–19), and after Elijah was taken up into the whirlwind, he was accepted as the leader of the sons of the prophets, and became noted in Israel. He possessed, according to his own request, "a double portion" of Elijah's spirit (2 Kings 2:9); and for sixty years (892–832 BC) held the office of "prophet in Israel" (2 Kings 5:8).

His name first occurs in the command given to Elijah to anoint him as his successor (1 Kings 19:16). After learning, in the cave on Mount Horeb, that Elisha, the son of Shaphat, had been selected by God as his successor in the prophetic office, Elijah set out to make known the Divine will. On his way from Sinai to Damascus, Elijah found Elisha "one of them that were ploughing with twelve yoke of oxen". Elisha delayed only long enough to kill the yoke of oxen, whose flesh he boiled with the very wood of his plough. He went over to him, threw his mantle over Elisha's shoulders, and at once adopted him as a son, investing him with the prophetic office. Elisha accepted this call about four years before the death of Israel's King Ahab. For the next seven or eight years Elisha became Elijah's close attendant until Elijah was taken up into heaven. During all these years we hear nothing of Elisha except in connection with the closing scenes of Elijah's life.

Elisha Gray (August 2, 1835 – January 21, 1901) was an American electrical engineer who co-founded the Western Electric Manufacturing Company. Gray is best known for his development of a telephone prototype in 1876 in Highland Park, Illinois and is considered by some writers to be the true inventor of the variable resistance telephone, despite losing out to Alexander Graham Bell for the telephone patent.

Gray is also considered to be the father of the modern music synthesizer, and was granted over 70 patents for his inventions.

Born into a Quaker family in Barnesville, Ohio, Gray was brought up on a farm. He spent several years at Oberlin College where he experimented with electrical devices. Although Gray was not a graduate of Oberlin College, he taught electricity and science at Oberlin and built laboratory equipment for Oberlin science departments.

In 1862 while at Oberlin, Gray met and married Delia Minerva Shepard.

In 1865 Gray invented a self-adjusting telegraph relay that automatically adapted to varying insulation of the telegraph line.
