Volta got electrical battery idea from dissection of a frog
Alessandro Volta, credited with electrical battery's invention, got the idea when fellow Italian physicist Galvani observed that frog's legs twitched when touched by two metal rods, interpreting it as 'animal electricity'. However, Volta, who was born on February 18, 1745, considered electricity to be 'metallic' and piled metal disks between brine-soaked paper to make the first battery, in 1800.
