James M. Spangler
James Murray Spangler was an American inventor, salesman and janitor who invented the first commercially successful portable electric vacuum cleaner that revolutionized household carpet cleaning. His device was not the first vacuum cleaner. However, Spanglers device was the first that was practical for home use. It was the first to use both a cloth filter bag and cleaning attachments. Spangler improved this basic model and received a patent for it in 1908. He formed the Electric Suction Sweeper Company to manufacture his device. William H. Hoover was so impressed with the vacuum cleaner that he bought into Spanglers business and patents.
Spangler was one of ten children born to Mr. William Spangler amp Mrs. Elizabeth Lind Spangler on November 20, 1848. The Spangler family was originally from Plains Township, Pennsylvania and settled in Stark County, Ohio.
