JOHN HAYS HAMMOND
He signs a short sentiment on a 5x3 card.
Autograph Sentiment signed: "Very sincerely/John Hays Hammond/Washington D.C./Dec. 1930", 5x3 card. John Hays Hammond (1855-1936) was an American mining engineer and businessman who worked for British mining firms in South Africa, working for Cecil Rhodes. After the Jameson raid of January 1896, a failed attempt - not supported by Hammond - to overthrow the Transvaal government, he was arrested and sentenced to death but released after payment of a fine. Returning to London and then the U.S., Hammond traveled extensively to examine mines in the U.S. and Mexico. Between 1926 and 1929, Hammond built a medieval style mansion in Gloucester, Massachusetts, known today as Hammond Castle. It also housed Hammond's laboratory, from which he patented over 400 inventions. Hammond, second only to Thomas Edison in number of patents granted, is especially known for developing radio remote control technology. Slightly worn. Otherwise, fine condition.
