Alfred Krupp |
, Germany |
The inventor was "principal of the house of Frederick Krupp, of Essen, in the Kingdom of Prussia, Germany, but now of Leicester Square, in the county of Middlex, a subject of the King of Prussia". What is intriguing is that by 1876 Thomas Prosser & Son was the U.S. representative of Fried. Krupp Works of Essen.
From a website (see link) on the Prosser mansion in Brooklyn: "Prosser was born in England, in 1829. His family came to America when he was a child, and eventually settled in New Jersey, where his father started a steel manufacturing company in Paterson, in 1851. Over in Germany, Alfred Krupp was growing his father's steel works in to a large successful company, with much of its revenue stream coming from the sale of iron rail for trains, as well as a growing armaments business. ... In a fateful meeting at the London Crystal Palace Exhibition in 1851, Thomas Prosser and Alfred Krupp met, and struck up a friendship and business partnership, so that in 1852, the Prosser Ironworks became the American agents for Krupp, and a very profitable relationship for both companies began that would continue until right before World War I." |
