Today’s Google homepage pays tribute to the inventor of the first electrical battery Alessandro Volta. The doodle marks Volta’s 270th birthday with an animated image of the world’s first electric battery powering the Google letters.
After watching a dead frog’s leg twitch when they were touched by two metals, Volta got the idea for his invention — stacking alternating metal discs separated by cardboard and seawater-soaked cloth.
The logo illustrates Volta’s battery lighting up the Google letters, and includes typographic details like Volta’s name, the elements he used, and the year he invented the battery.
“One key idea I wanted to communicate was how the voltage of the battery increased as the stack grew,” said doodler Mark Holmes who designed the logo. Holmes said he wanted the doodle to look like it could have been the first advertisement for the world’s first electrical battery.
