Who was the inventor of the water pump in mines?

By 1711, Thomas Newcomen completed making his first commercial engine. It could do the work of team if 500 horses! In 1712, Newcomen and John Calley built their first engine on top of a water-filled mine shaft to demonstrate its power, pumping it out in hours. Soon, orders from wet mines all over England began to pour in it. Although its first use was in a coal-mining area, Newcomen’s engine would find its greatest use pumping water out of the mineral mines in his native West Country, such as the tin mines of Cornwall. Before Newcomen died, he had installed over a hundred of his engines in the mining districts of the Britain. By 1725, this engine was in common use in collieries and it held its place without material change for about three-quarters of a century. In 1765, James Watt, the steam engine man, while working for the University of Glasgow, was asked to repair a Newcomen engine which was deemed inefficient but was the best steam engine of its time. That set the inventor to work on several improvements to Newcomen’s design.
