The Daniell cell (var. sp. Daniel cell), also called the gravity cell or crowfoot cell was invented in 1836 by John Frederic Daniell, who was a British chemist and meteorologist. The Daniell cell was a great improvement over the voltaic pile used in the early days of battery development. The Daniell cell's theoretical voltage is 1.1 volts and the chemical reaction is Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s).

"Then the king arose very early in the morning, and went in haste unto the den of lions. And when he came near unto the den to Daniel, he cried with a lamentable voice; the king spake and said to Daniel, O Daniel, servant of the living God, is thy God, whom thou servest continually, able to deliver thee from the lions? Then said Daniel unto the king, O king, live for ever. My God hath sent his angel, and hath shut the lions' mouths, and they have not hurt me; forasmuch as before him innocency was found in me; and also before thee, O king, have I done no hurt. Then was the king exceeding glad, and commanded that they should take Daniel up out of the den. So Daniel was taken up out of the den, and no manner of hurt was found upon him, because he had trusted in his God." Daniel 6:19-23 ASV
