John Adams Whipple (September 10, 1822 – April 10, 1891) was an American inventor and early photographer. He was the first in the United States to manufacture the chemicals used for daguerreotypes. He pioneered astronomical and night photography. He was a prize-winner for his extraordinary early photographs of the moon and he was the first to produce images of stars other than the sun. Among those was the star Vega and the Mizar-Alcor stellar sextuple system, which was thought to be a double star until 2009.
