In 1866, Porter was given a gift of
$20,000 by his father, which changed the course of his life. He invested that money with a partner,
John Y. Smith, and formed the Smith & Porter Machine works. They opened a small shop in
Pittsburgh, Pennsylvania, which grew to become
H.K. Porter, Inc. Porter served as president of the company. He was President of the Pittsburgh YMCA from 1868 to 1887, and was President of the
Western Pennsylvania Institute for the Blind in 1904. He served in the
United States House of Representatives in the
58th United States Congress from 1903 to 1905 as an Independent Republican. Porter represented
Pennsylvania's 31st congressional district. == Later life and death ==
