U.S. Navy, Inventor
He was commissioned as an ensign in the U.S. Navy. During his ensuing naval service, he first served on the USS Richmond, then the USS Minnesota. While his ship was in Newport, Rhode Island, in 1881, Sprague invented the inverted type of dynamo. After he was transferred to the USS Lancaster, flagship of the European Squadron, he installed the first electric call-bell system on a U.S. Navy ship. Sprague took leave to attend the Paris Electrical Exhibition in 1881 and the Crystal Palace Exhibition in Sydenham, England in 1882, where he was on the jury of awards for gas engines, dynamos and lamps.

Famous quotes containing the word inventor:
“We have all heard of Young America. He is the most current youth of the age.
Some think him conceited, and arrogant; but has he not reason to entertain a rather extensive opinion of himself? Is he not the inventor and owner of the present, and sole hope of the future?”
—Abraham Lincoln (1809–1865)
