Leverett Bradley
1798 - 1875
Leverett Bradley was born on 25 Nov 1798. He died 2 on 6 Sep 1875 in Jersey City, New Jersey, USA.
In the Fall of 1869, Thomas Alva Edison operated a small shop in the electrical instrument factory of Leverett Bradley in Jersey City, New Jersey.
Dr. Bradley has been well known as an electrician of considerable ability; but he is best known from the invention which he patented in 1865, for winding helices with uncovered wire. In 1859 he secured a patent for an automatic telegraph apparatus with which, on a short circuit, he succeded in recording about 15,000 words per hour, but he was unable to practically work the apparatus on a telegraphic line of ordinary length. In 1878 he obtained a patent for an apparatus for electric measurement, being a combination of a tangent galvanometer and rheostat, which proved very successful, and is now being much used in colleges and other institutions of learning, as a means of instruction and experiment.
