question: Electrophorus was improved by an Italian physicist credited as the inventor of what?
answer: the electrical battery
context: Title: Electrophorus
  Passage: An electrophorus or electrophore is a simple manual capacitive generator used to produce electrostatic charge via the process of electrostatic induction.  A first version of it was invented in 1762 by Swedish professor Johan Carl Wilcke, but Italian scientist Alessandro Volta improved and popularized the device in 1775, and is sometimes erroneously credited with its invention.  The word "electrophorus" was coined by Volta from the Greek ήλεκτρον ('elektron'), and ϕέρω ('phero'), meaning 'electricity bearer'.
  Title: Temistocle Calzecchi-Onesti
  Passage: Temistocle Calzecchi Onesti (December 14, 1853 – November 25, 1922) was an Italian physicist and inventor born in Lapedona, Italy, where his father, Icilio Calzecchi, a medical doctor from nearby Monterubbiano, was temporarily working at the time.  His mother, Angela, was the last descendant of the ancient and noble Onesti family.  His first name is the Italian version of the Athenian general Themistocles.
  Title: Federico Faggin
  Passage: Federico Faggin (born December 1, 1941), is an Italian physicist, inventor and entrepreneur, widely known for designing the first commercial microprocessor.  He led the 4004 (MCS-4) project and the design group during the first five years of Intel's microprocessor effort.  Most importantly, Faggin created in 1968, while working at Fairchild Semiconductor, the self-aligned MOS silicon gate technology (SGT) that made possible dynamic memories, non-volatile memories, CCD image sensors, and the microprocessor.  In addition, he further developed at Intel his original SGT into a new methodology for random logic chip design that was essential to the creation of the world’s first single chip microprocessor and all other early Intel microprocessors.  He was co-founder, with Ralph Ungermann, and CEO of Zilog, the first company solely dedicated to microprocessors.  He was also co-founder and CEO of Cygnet Technologies and of Synaptics.
  Title: Theodore Harold Maiman
  Passage: Theodore Harold "Ted" Maiman (July 11, 1927 – May 5, 2007) was an American engineer and physicist credited with the building of the first working laser.  Maiman's laser led to the subsequent development of many other types of lasers.  The laser was successfully fired on May 16, 1960.  In a July 7, 1960 press conference in Manhattan, Maiman and his employer, Hughes Aircraft Company, announced the laser to the world.  Maiman was granted a patent for his invention, and he received many awards and honors for his work.  Maiman's experiences in developing the first laser and subsequent related events are described in his book, "The Laser Odyssey".
  Title: Galileo Ferraris
  Passage: Galileo Ferraris (31 October 1847 – 7 February 1897) was an Italian physicist and electrical engineer, one of the pioneers of AC power system and the inventor of induction motor.  Many newspapers touted that his work on the induction motor and power transmission systems were some of the greatest inventions of all ages.  He published an extensive and complete monograph on the experimental results obtained with open-circuit transformers of the type designed by the power engineers Lucien Gaulard and John Dixon Gibbs.
  Title: Giovanni Caselli
  Passage: Father Giovanni Caselli (8 June 1815 – 25 April 1891) was an Italian physicist, inventor and priest.  He is the inventor of the pantelegraph (a.k.a. Universal Telegraph or "all-purpose telegraph"), the predecessor of the modern fax machine.  The world's first practical operating facsimile machine ("fax") system put into use was by Caselli.
  Title: Bernd T. Matthias
  Passage: Bernd Theodor Matthias (June 8, 1918 – October 27, 1980) was a German-born American physicist credited with discoveries of hundreds of elements and alloys with superconducting properties.
  Title: Alessandro Volta
  Passage: Alessandro Giuseppe Antonio Anastasio Volta (] ; 18 February 1745 – 5 March 1827) was an Italian physicist, chemist, and a pioneer of electricity and power, who is credited as the inventor of the electrical battery and the discoverer of methane.  He invented the Voltaic pile in 1799, and reported the results of his experiments in 1800 in a two-part letter to the President of the Royal Society.  With this invention Volta proved that electricity could be generated chemically and debunked the prevalent theory that electricity was generated solely by living beings.  Volta's invention sparked a great amount of scientific excitement and led others to conduct similar experiments which eventually led to the development of the field of electrochemistry.
  Title: Shigeo Satomura
  Passage: Shigeo Satomura (里村 茂夫 , Satomura Shigeo , 1919–1960) was a Japanese physicist credited with introducing the ultrasonic Doppler techniques to practical medical diagnostics in the 1950s.  These techniques made possible non-invasive monitoring of blood flow in the human body.
  Title: Felice Fontana
  Passage: Felice Fontana (15 April 1730 – 10 March 1805) was an Italian physicist who discovered the water gas shift reaction in 1780.  He is also credited with launching modern toxicology and investigating the human eye.
